  • The social construction of a health controversy. The case of electricity
           smart meters in France
    • Authors: Laura Draetta
      Pages: 5 - 15
      Abstract: This article presents a sociological study of the public controversy over electricity smart meters in France. It asks how this controversy has emerged nationally and how, rather than waning as a result of expertise produced to dispel uncertainty, it has instead grown stronger. Drawing on an in-depth cross-analysis of the French press published over the period 2015–2016 and a heterogeneous corpus of institutional documents, the study highlights the public, multidimensional, and health-focused nature of the controversy, as well as its origin from scares imported from abroad. Above all, it reveals how this controversy extends beyond discussion of the intrinsic qualities of the technical object itself (the smart meter) to fuel reflection on the anti-democratic dimension of the rollout project.

  • Setting exposure guidelines and product safety standards for
           radio-frequency exposure at frequencies above 6 GHz: brief review
    • Authors: Akimasa Hirata; Daisuke Funahashi; Sachiko Kodera
      Pages: 17 - 24
      Abstract: Two international guidelines/standards for human protection from electromagnetic fields are on-going revision. Most attention has been paid to the revisions above 3 or 10 GHz where the new fifth generation wireless communication system will be deployed soon. The frequency of 3 or 10 GHz is the transition frequency at which the metric of the basic restriction is changed from the specific absorption rate to the power density. Rationales for the metrics above 3 or 10 GHz were not well established when the current guidelines/standards were published. In this review, we focused on three issues to be considered in the next revision of the exposure guidelines: (i) the averaging area of the power density, (ii) the transition frequency at which the metric is changed from the specific absorption rate to the power density, and (iii) the exposure averaging time. In addition, some remarks and trends on related product safety will also be reviewed and discussed briefly.

  • RF-EMF exposure induced by mobile phones operating in LTE small cells in
           two different urban cities
    • Authors: Taghrid Mazloum; Sam Aerts; Wout Joseph; Joe Wiart
      Pages: 35 - 42
      Abstract: With the huge growth in data traffic, the densification of the macro cell (MC) layer with low-powered small cell (SC) base stations (resulting in a heterogeneous network) will improve network performances in terms of radio coverage and capacity. However, this may influence the human exposure to radiofrequency electromagnetic fields (RF-EMFs). Through measurement campaigns in two different urban cities (in France and the Netherlands), the authors characterized the RF-EMF exposure induced by LTE (Long-Term Evolution) MC and SC networks, while considering radio emissions from both base stations (downlink or DL) and user equipment (uplink or UL). For an internet data usage and with respect to an MC connection, results showed that an SC connection may increase the DL exposure while decreasing the UL exposure (with a factor of 5 to 17), mainly due to the lower mobile phone emitted power and depending on whether the throughput is limited or not. Furthermore, the city with a dense network is characterized by low UL exposure and high DL exposure.

  • A new extrapolation expression for exposure evaluation inside a
           human-equivalent liquid phantom in the vicinity of wireless power transfer
    • Authors: Satoshi Shimoyama; Jerdvisanop Chakarothai; Kanako Wake; Takuji Arima; Soichi Watanabe; Toru Uno
      Pages: 53 - 65
      Abstract: To ensure human safety against electromagnetic exposures from wireless power transfer (WPT) systems operating at MHz-band frequencies, a compliance test must be conducted using either numerical simulations or measurements. In practice, measurements of the specific absorption rate (SAR) inside a human-equivalent liquid phantom are required for exposure evaluation. However, accurate measurements of SAR are difficult, especially at a location close to the phantom boundary, owing to the boundary effect, caused by the field disturbance due to the SAR probe itself. Hence, it is necessary to use an extrapolation method to determine the internal electric field or SAR. In this study, we propose a new extrapolation expression based on the characteristic of electromagnetic fields inside the phantom in order to estimate internal electric field strength or SAR. The validity of the proposed expression was demonstrated both numerically and experimentally. From the results, we confirmed that the difference in the internal electric field strength inside a liquid phantom was less than 3% between our proposed extrapolation expression and the method of moments (MoM). For SAR measurements using two types of actual WPT systems, i.e., solenoid and flat-spiral types, we found that the proposed expression can be used to evaluate the spatial peak 10-g average SAR with a difference of less than 30% compared with those numerically obtained by MoM.

  • Experimental analysis of individual EMF exposure for GSM/UMTS/WLAN user
    • Authors: Milica Popović; Mladen Koprivica; Jelena Milinković; Aleksandar Nešković
      Pages: 79 - 91
      Abstract: Individual exposure to electromagnetic field (EMF) originating from a user device when using different services over WLAN (Wireless Local Area Network), GSM (Global System for Mobile communications), and UMTS (Universal Mobile Telecommunications Service) technologies in different radio conditions is analyzed. The most common types of traffic were chosen (voice, Skype, web browsing, download, upload, video, audio, TV) and tested in areas of good, medium, and bad radio conditions, per wireless technology. Exposure is evaluated using triggered network reports and external measurements performed in a live network, and also using predetermined simulation results. The analysis shows strong dependence of individual EMF exposure on wireless technology, radio conditions, and service used. For all technologies and services, exposure increased with deterioration of radio conditions, except for file upload over UMTS where in bad radio conditions exposure decreased due to impact of higher layer protocols. GSM technology generated highest exposure in all radio conditions and for all services, except file upload service in good radio conditions where WLAN generated higher exposure. File upload service generated highest exposure for all technologies and radio conditions, except for GSM in good radio conditions where video streaming and voice were ahead.

  • Children exposure to femtocell in indoor environments estimated by sparse
           low-rank tensor approximations
    • Authors: Emma Chiaramello; Marta Parazzini; Serena Fiocchi; Marta Bonato; Paolo Ravazzani; Joe Wiart
      Pages: 113 - 121
      Abstract: The exposure of an 8-year-old child to a femtocell operating at 2600 MHz, both (child and source) freely located in random positions in an indoor environment, was assessed. In order to develop surrogate models of the exposure, stochastic dosimetry based on sparse low-rank tensor approximation method (sparse LRA) was used. The surrogate models were used for fastly estimating the specific absorption rate (SAR) in all the possible positions of femtocell and child. Results showed that, for all the possible positions in the room, the exposure values were significantly below the International Commission of Non-Ionizing Radiation Protection (ICNIRP) guidelines for general public and that the probability of reaching SAR values higher than 1% of the ICNIRP guidelines value was lower than 0.006. The variation of the distance between femtocell and child influenced greatly the exposure, resulting in quartile coefficient of dispersion values always higher than 48%.

  • Recovering SQLite data from fragmented flash pages
    • Abstract: As a small-sized database engine, SQLite is widely used in embedded devices, such as mobile phones and PDAs. Large amounts of sensitive personal data are stored in SQLite. Any unintentional data deletion or unexpected device damage can cause considerable loss to the owners of the data. Therefore, in these cases, it is necessary to be able to recover and extract SQLite data records from the flash memory of portable devices. However, most existing SQLite recovery studies take the database file as the research subject, while it is not possible to acquire an intact database file when the flash memory controller is damaged. This paper presents a new method to recover SQLite data records from fragmented flash pages. Instead of investigating the whole *.db file or the journal file, the suggested method focuses on the analysis of B-Tree leaf page structure, which is the basic storage unit, to locate and extract existing and deleted data records based on the structures of the page header and cells in the leaf page, and then uses the SQLite_master structure to translate hex data records into meaningful SQLite tables. The experimental results show that this new method is effective regardless of which file system is used.

  • Popularity prediction–based caching in content delivery networks
    • Authors: Nesrine Ben Hassine; Pascale Minet; Dana Marinca; Dominique Barth
      Abstract: In content delivery networks (CDNs), caches are resources that must be allocated. For that purpose, videos’ popularity knowledge helps to make efficient decisions about which videos should be cached. Thus, we must be able to anticipate future needs in terms of requested videos. To do this, we rely on the requests history. This paper focuses on predicting the videos’ popularity: the daily number of requests. For that purpose, we propose a two-level prediction approach. At the first level, the experts compute the videos’ popularity, each expert using its own prediction method with its own parameters. At the second level, the forecasters select the best experts and build a prediction based on the predictions provided by these experts. The prediction accuracy is evaluated by a loss function as the discrepancy between the prediction value and the real number of requests. We use real traces extracted from YouTube to compare different prediction methods and determine the best parameter tuning for experts and forecasters. The goal is to find the best trade-off between complexity and accuracy of the prediction methods used. Finally, we apply these prediction methods to caching. Prediction methods are compared in terms of cache hit ratio and update ratio. The gain brought by this two-level prediction approach is compared with that obtained by a single prediction level. The results show that the choice of a two-level prediction approach is justified.

  • Isolation in cloud computing infrastructures: new security challenges
    • Authors: Mohammad-Mahdi Bazm; Marc Lacoste; Mario Südholt; Jean-Marc Menaud
      Abstract: Cloud computing infrastructures share hardware resources among different clients, leveraging virtualization to multiplex physical resources among several self-contained execution environments such as virtual machines or Linux containers. Isolation is a core security challenge for such a computing paradigm. It may be threatened by side-channels, created due to the sharing of physical resources like processor caches, or by mechanisms implemented in the virtualization layer. Side-channel attacks (SCAs) exploit and use such leaky channels to obtain sensitive data such as kernel information. This paper aims to clarify the nature of this threat for cloud infrastructures. Current SCAs are performed locally and exploit isolation challenges of virtualized environments to retrieve sensitive information. This paper also clarifies the concept of distributed side-channel attack (DSCA). We explore how such attacks can threaten isolation of any virtualized environments such as cloud computing infrastructures. Finally, we study a set of different applicable countermeasures for attack mitigation in cloud infrastructures.

  • Lattice-based dynamic group signature for anonymous authentication in IoT
    • Authors: Run Xie; Chanlian He; Chunxiang Xu; Chongzhi Gao
      Abstract: Anonymous authentication is one of the most critical tools for the privacy protection in Internet-of-Things (IoT). The primitive of group signature has been widely applied to achieving anonymous authentication. Any mobile device is able to prove its privilege of the access control to a remote server which is an authenticated device with valid attestation. However, the traditional group signature schemes cannot support dynamic authentication efficiently. Furthermore, they are insecure against quantum attack. To tackle the abovementioned challenges, a new lattice-based dynamic group signature scheme is proposed. The new scheme allows any user to dynamically join the group while achieving efficient revocation. Furthermore, it is shown that the new scheme can achieve the security of non-frameability. The security of non-frameability guarantees that any user’s signature can not be forged by other users in the system. In addition, the scheme based on the hardness of lattice problem in the random oracle model is provably secure. The efficiency analysis demonstrates that the scheme is effective in practice.

  • Statistical network protocol identification with unknown pattern
    • Authors: Yu Wang; Hanxiao Xue; Yang Liu; Waixi Liu
      Abstract: Network traffic classification is an enabling technique for network security and management for both traditional networks and emerging networks such as Internet of Things. Due to the decreasing effectiveness of traditional port-based and payload-based methods, lots of research attentions are devoted to an alternative approach based on flow and packet-level traffic characteristics. A variety of statistical classification schemes are proposed in this context, but most of them embody an implicit assumption that all protocols are known in advance and well presented in the training data. This assumption is unrealistic because real-world networks constantly witness emerging traffic patterns and protocols that are previously unknown. In this paper, we revisit the problem by proposing a learning scheme with unknown pattern extraction for statistical protocol identification. The scheme is designed with a more realistic setting, in which we assume that the training data only consists of labeled samples from a limited number of protocols, and the goal is to identify these known patterns out of arbitrary traffic mixture of both known and unknown protocols. Our experiments based on real-world traffic show that the proposed scheme outperforms previous approaches by accurately identifying both known and unknown protocols.

  • Fine-grained multi-authority access control in IoT-enabled mHealth
    • Authors: Qi Li; Hongbo Zhu; Jinbo Xiong; Ruo Mo; Zuobin Ying; Huaqun Wang
      Abstract: With the popularity of Internet of Things (IoT) and cloud computing technologies, mobile healthcare (mHealth) can offer remote, accurate, and effective medical services for patients according to their personal health records (PHRs). However, data security and efficient access of the PHR should be addressed. Attribute-based encryption (ABE) is regarded as a well-received cryptographic mechanism to simultaneously realize fine-grained access control and data confidentiality in mHealth. Nevertheless, existing works are either constructed in the single-authority setting which may be a performance bottleneck, or lack of efficient user decryption. In this paper, we propose SEMAAC, a secure and efficient multi-authority access control system for IoT-enabled mHealth. In SEMAAC, there are multiple independently worked attribute authorities (AAs). A new entity could be an AA without re-building the system. To reduce the user decryption overhead, most decryption is executed in cloud server, which whereafter returns a partial decryption ciphertext (PDC). The AAs can help the user to check if the PDC is correctly computed. Additionally, a restricted user can delegate his/her key to someone to outsource the decryption and check the returned result, without exposing the plaintext PHR file. The proposed SEMAAC is proved to be adaptively secure in the standard model. The numerical analysis and extensive experiments illustrate the efficiency and advantage of our scheme.

Resource-limited devices outsource the processing and storage of massive numbers of sequential elements to cloud-based servers, and security protection is of primary importance for the outsourced streams. The streaming authenticated data structure schemes and verifiable data streaming schemes are introduced to provide data owners and verifiers with the ability to verify streaming elements. However, due to their enormous numbers of key parameters, expensive updating overheads, signature revocation, and other security and application problems, few of the existing schemes are feasible when massive numbers of streaming elements are involved and allowed to be updated. In this paper, we define and construct a new primitive, namely, dimension-increasing vector commitment (DIVC). Then, we present the definition of constant verifiable data streaming (CVDS), which is an extension of the original verifiable data streaming (VDS) scheme. Moreover, with the proposed DIVC scheme, which is based on the CDH assumption in bilinear pairings, we construct two concrete CVDS schemes, namely, the probabilistic verifiability CVDS (P-CVDS) scheme and the deterministic verifiability CVDS (D-CVDS) scheme, by respectively employing the counting Bloom filter and a dynamic accumulator, which is based on the q-SDH assumption in bilinear pairings. The analyses prove that both the P-CVDS and D-CVDS schemes satisfy the security requirements that are formulated in the CVDS definition. Finally, the efficiency and performance evaluation demonstrate that the proposed schemes are feasible in practical applications.

  • Mitigation of human EMF exposure in downlink of 5G
    • Authors: Imtiaz Nasim; Seungmo Kim
      Abstract: While cellular communications operating at higher frequencies (i.e., above 6 GHz) have been attracting significant research interest, their potentially harmful impacts on human health are not studied as significantly. Few existing studies discussing the human health impacts above 6 GHz paid attention to uplink only, due to close contact of a transmitter to a human body. This paper claims the necessity of thorough investigation in downlink on human exposure to electromagnetic fields (EMFs). Our simulation results suggest the downlink of a Fifth Generation Cellular Mobile Communications (5G) system can generate significantly higher power density (PD) and specific absorption rate (SAR) than the previous generations of wireless systems. Our study also highlights the significance of considering SAR as a metric in evaluation of the EMF exposure at high frequencies. Moreover, this paper proposes a downlink protocol that guarantees the EMF exposure level under a threshold while keeping the data rate above the 5G requirements.

  • Statistical model of the human RF exposure in small cell environment
    • Authors: A. Chobineh; Y. Huang; T. Mazloum; E. Conil; J. Wiart
      Abstract: Small cells are one of the solutions to face the imperative demand on increasing mobile data traffic. They are low-powered base stations installed close to the users to offer better network services and to deal with increased data traffic. In this paper, the global exposure induced in such networks as a whole from user equipment and base stations has been investigated. As the small cell is close to the user, the propagation channel becomes highly variable and strongly susceptible by environmental factors such as the road traffic. An innovative statistical path loss model is constructed based on measurements on two French commercial LTE small cells, operating at LTE 1800 MHz and 2600 MHz. This statistical path loss model is then used to assess global exposure of the adult proportion of a population in a scenario composed of a street lined with buildings and indoor and outdoor data users.

  • Whole-body average SAR measurement using flat phantoms for radio base
           station antennas and its applicability to adult and child human models
    • Authors: Takahiro Iyama; Teruo Onishi; Kensuke Sasaki; Tomoaki Nagaoka; Lira Hamada; Soichi Watanabe
      Abstract: The specific absorption rate (SAR) measurement procedure for radio base station antennas using flat phantoms has been investigated and standardized by the International Electrotechnical Commission (IEC). This paper discusses the effectiveness of this procedure for considering Japanese human models based on numerical simulations with validation of whole-body average SAR (WBSAR) measurement. The WBSAR in two Japanese anatomical human models (adult male and 3-year-old child) and two box-shaped phantoms (large and small) using a standardized SAR measurement procedure are compared at 788 MHz and 3.5 GHz. Computational results show that the SAR measurement procedure in the IEC leads to overestimated WBSAR compared to those in Japanese anatomical human models. These results imply that the SAR measurement procedure above is applicable to not only some commonly used but Japanese human models. The WBSAR obtained using SAR estimation formulae in the IEC is also overestimated compared to those in Japanese anatomical human models. In addition, to reduce the measurement time and simplify the post-processing, this paper introduces a SAR measurement procedure based on the two-dimensional SAR distribution around the surface of the bottom of the phantom and the one-dimensional exponential decay of the SAR distribution in the direction of the phantom depth. SAR measurement examples of antennas for small radio base stations are also presented.

  • The effect of antenna polarization and body morphology on the measurement
           uncertainty of a wearable multi-band distributed exposure meter

      Abstract: This paper studies the effect of antenna polarization on measurement uncertainty of a multi-band body-worn distributed exposure meter (BWDM). The BWDM is a device for assessing electromagnetic fields in real environments accurately. The BWDM consists of 8 nodes and is calibrated on the body for simultaneous measurement of the incident power density in four frequency bands. Each node contains an antenna that can have two potential antenna polarizations.The BWDM is calibrated on four human subjects in an anechoic chamber to determine its measurement uncertainty in terms of 68% confidence interval (CI68) of the on-body antenna aperture. The results show that using a fixed polarization of the antennas on body can lead to a different CI68 up to maximum 4.9 dB when worn by another person which is still 9.6 dB lower than the measurement uncertainty of commercial exposure meters.

  • Numerical evaluation of human exposure to 3.5-GHz electromagnetic field by
           considering the 3GPP-like channel features
    • Authors: Congsheng Li; Chunying Xu; Ruixin Wang; Lei Yang; Tongning Wu
      Abstract: Human exposure to 3.4–3.6-GHz radiofrequency (RF) electromagnetic field (EMF), which is the frequency band utilized by trial test of the fifth-generation mobile communication systems (5G), has been numerically analyzed in the study. The study evaluated the EMF exposure of this frequency band by taking into account of the channel features. Two exposure scenarios were reconstructed according to the technical specification on channel modeling from the 3rd Generation Partnership Project. The channel features of the reconstructed EMF were numerically validated. The equivalent source principle and the finite-difference time-domain method were applied to calculate the RF energy specific absorption (SA) using three human models. The results revealed that the exposure scenarios with various channel features affected whole-body SA (WBSA) by about 50–70%. The variation was mainly introduced by the configuration of the incident waves defined by the channel models. Dosimetric difference between the two exposure scenarios for some tissues has been presented and discussed. The results demonstrated that the anatomy of the model was also a factor influencing SA.
