  • Needle in a Haystack: Detecting Subtle Malicious Edits to Additive
           Manufacturing G-Code Files

      Abstract: Increasing usage of digital manufacturing (DM) in safety-critical domains is increasing attention on the cybersecurity of the manufacturing process, as malicious third parties might aim to introduce defects in digital designs. In general, the DM process involves creating a digital object (as CAD files) before using a slicer program to convert the models into printing instructions (e.g., g-code) suitable for the target printer. As the g-code is an intermediate machine format, malicious edits may be difficult to detect, especially when the golden (original) models are not available to the manufacturer. In this work, we aim to quantify this hypothesis through a red team/blue team case study, whereby the red team aims to introduce subtle defects that would impact the properties (strengths) of the 3-D printed parts, and the blue team aims to detect these modifications in the absence of the golden models. The case study had two sets of models, the first with 180 designs (with two compromised using two methods) and the second with 4320 designs (with 60 compromised using six methods). Using statistical modeling and machine learning (ML), the blue team was able to detect all the compromises in the first set of data, and 50 of the compromises in the second.

      Abstract: Fiber-reinforced composite parts used in drones, automobiles, and sports equipment are now being manufactured by additive manufacturing (AM), where the material parameters such as fiber direction can be changed within a layer or from one layer to the other. Nondestructive evaluation methods are required to assess the quality of such customized printed parts. In this work, a microcomputed tomography ( $mu $ CT) dataset is analyzed to determine the fiber content in a 3-D printed composite material part using a digital binary image processing method. The existing literature on binary image analysis methods to measure the fiber volume fraction is limited to continuous fiber reinforced composites. Discontinuous fiber reinforced 3-D printing filaments are popular in manufacturing parts with increased strength. The methods developed in this work expands the binary image process to scans that show fibers embedded lengthwise in different directions in the 3-D printed layers. An optimized thresholding method is trained on the filament sample and then applied to 3-D printed samples. The results show fiber volume fraction measurements with standard deviations below 0.15%. The results in this work will be useful for product quality validation.

  • Supporting Safe Priority Adjustment for Software-Defined Real-Time
           Networking

    • Free pre-print version: Loading...

      Authors: Sangeun Oh;Kilho Lee;
      Pages: 119 - 122
      Abstract: It is essential to support real-time communication in networked control systems, such as automotive systems or smart factories. Several studies have been conducted to schedule real-time flows by adjusting their priorities using software-defined networking (SDN). However, because its architecture was not initially designed for real-time communication, unexpected challenges may occur if it is not utilized carefully. In particular, because SDN does not provide an atomic method for priority adjustment, some flows may violate their timing constraints by receiving additional interference during priority adjustment. In this letter, we propose novel schemes to update the flow priorities safely in SDN-based real-time systems. To this end, we first analyze such problems through two types of cases. Then, we develop schemes that determine a safe procedure for priority adjustment and synchronize the priority settings of all switches. By network emulations, we demonstrate that the above problem occurs in 149 out of 300 flow sets, but our schemes can effectively prevent all of them.

  • Optimizing Learned Bloom Filters: How Much Should Be Learned'

      Authors: Zhenwei Dai;Anshumali Shrivastava;Pedro Reviriego;José Alberto Hernández;
      Pages: 123 - 126
      Abstract: The learned Bloom filter (LBF) combines a machine learning model (learner) with a traditional Bloom filter to improve the false positive rate (FPR) that can be achieved for a given memory budget. The LBF has recently been generalized by making use of the full spectrum of the learner’s prediction score. However, in all those designs, the machine learning model is fixed. In this letter, for the first time, the design of LBFs is proposed and evaluated by considering the machine learning model as one of the variables in the process. In detail, for a given memory budget, several LBFs are constructed using different machine learning models and the one with the lowest FPR is selected. We demonstrate that our approach can achieve much better performance than existing LBF designs providing reductions of the FPR of up to 90% in some settings.

  • Secure Register Allocation for Trusted Code Generation

      Authors: Priyanka Panigrahi;Vemuri Sahithya;Chandan Karfa;Prabhat Mishra;
      Pages: 127 - 130
      Abstract: In this letter, we investigate the inherent vulnerability of register allocation (RA) in which the variables of a source program are mapped to the registers in hardware. This letter makes three important contributions. Specifically, we show that RA is secure if there is no spilling. Next, we show that RA with spilling does not preserve the security properties of the source program. Our experimental evaluation using a wide variety of benchmarks demonstrates that RA in LLVM is not secure. Finally, we propose a secure RA in LLVM that will not introduce additional information leaks in the generated code due to spilling.

      Authors: Rijoy Mukherjee;Rajat Subhra Chakraborty;
      Pages: 131 - 134
      Abstract: Deep neural network (DNN) hardware accelerators are being deployed widely to accelerate the inference process. Security of such accelerators is a major challenge, especially when being deployed in safety-critical systems such as autonomous vehicles. In this letter, we present novel Hardware Trojan (HT) attacks on two DNN hardware accelerators, which modifies the activation parameters of the DNN in a field-programmable gate array-based accelerator implementation. The proposed HT is agnostic to the detailed architecture of the DNN. Experimental results demonstrate that the proposed HT is extremely stealthy, and when activated can result in significant degradation in inference accuracy.

      Abstract: Discarded consumer electronics are a significant and growing source of hazardous waste. Repurposing smartphones has the potential to reduce the rate of disposal. However, reusing smartphones for general computational tasks is difficult due to the variety and domain specificity of the mobile software stack, and the relatively low computational power of these devices. We present the design and proof-of-concept implementation of Renée, a smartphone-based cluster built from used phones that provides function-as-a-service (FaaS) capabilities. Our experience indicates that reusing decommissioned smartphones for general computational tasks is not only feasible but also that a local cluster built from these devices has the potential to provide faster response times than commercial FaaS while reducing the yearly global warming potential of the reused devices.

      Authors: Ebelechukwu Esimai;Marly Roncken;
      Pages: 139 - 142
      Abstract: By means of a simple buffer design, we show that active versus passive and push versus pull settings in asynchronous communication protocols, also known as handshake protocols, can be controlled by initialization. We advocate postponing initialization until run time and show that postponement simplifies the design and design process and serves test, debug, and analysis. We design the buffer as a network of communication channels with storage, called Links, and storage-free computation modules, called Joints. We describe the behaviors of Links and Joints using a shared variable model presented here for the first time.

      Authors: Yong Zheng;Haigang Yang;Yi Shu;Yiping Jia;Zhihong Huang;
      Pages: 143 - 146
      Abstract: The network on chip (NoC) used in the AI chip is required to be able to deliver data to multiple destination endpoints simultaneously. The existing solutions, such as hierarchial mesh (HMESH) and FATTREE all modify the connection between routers to achieve multicasting. Although this method can achieve delivering data to multiple destination endpoints at the same time, it significantly increases the number of routers used and, therefore, brings a huge additional area and power consumption overhead. In order to solve this problem, this work designed a customized multicast-enabled tree-based NoC, named mTREE, by modifying the microarchitecture of the router, including the routing calculation unit, credit counter, and switch allocator. When implemented on Arria10 FPGA, mTREE only brings a 1% increase in resource utilization compared with the traditional tree-topology NoC. Compared with two other multicast-enabled NoCs: 1) FATTREE and 2) HMESH, mTREE can reach a $3.19times $ – $3.50times $ and $1.67times $ – $3.02times $ reduction in resource utilization, respectively, and a $4.81times $ – $8.01times $ and $2.85times $ – $3.03times $ reduction in energy consumption, respectively.

      Authors: Kris Nikov;Marcos Martínez;Simon Wegener;Jose Nunez-Yanez;Zbigniew Chamski;Kyriakos Georgiou;Kerstin Eder;
      Pages: 147 - 150
      Abstract: This letter a novel approach to event-based power modeling for embedded platforms that do not have a performance monitoring unit (PMU). The method involves complementing the target hardware platform, where the physical power data is measured, with another platform on which the CPU performance data, that is needed for model generation, can be collected. The methodology is used to generate accurate fine-grain power models for the Gaisler GR712RC dual-core LEON3 fault-tolerant SPARC processor with onboard power sensors and no PMU. A Kintex UltraScale field-programmable gate array (FPGA) is used as the support platform to obtain the required CPU performance data, by running a soft-core representation of the dual-core LEON3 as on the GR712RC but with a PMU implementation. Both platforms execute the same benchmark set and data collection is synchronized using per-sample timestamps so that the power sensor data from the GR712RC board can be matched to the PMU data from the FPGA. The synchronized samples are then processed by the Robust Energy and Power Predictor Selection (REPPS) software in order to generate power models. The models achieve less than 2% power estimation error when validated on an industrial use case and can follow program phases, which makes them suitable for runtime power profiling during development.

      Pages: 151 - 154
      Abstract: IoT systems are used for performing a variety of essential tasks in wide-ranging sectors, such as healthcare, smart cities, agriculture, and industrial automation. Most of these systems incorporate smartness for intelligent decision making using artificial intelligence (AI) approaches. To reduce the network bandwidth usage and load on the cloud server, there is a push to relegate most of these AI-related computations to edge IoT devices/systems. Hence, to ensure good performance, the edge devices must be systematically designed with an emphasis on the respective AI requirements from exploration to deployment. State-of-the-art IoT device and system design practices place little importance on the AI specifications during the early stages of the system development resulting in systems, which are unable to meet the AI specifications without additional redesigning and optimization efforts. In this letter, we propose an automated framework for AI-rooted IoT system design approach, where the AI specifications play a vital role in deciding the system components, design, and implementation from a very early stage of the design life cycle. The proposed framework employs an expert system and a machine-readable knowledge-base to automate the design process. Using a set of case studies, we demonstrate the benefits of the proposed framework.

  • Fast and High-Accuracy Approximate MAC Unit Design for CNN Computing

    • Free pre-print version: Loading...

      Authors: Hang Xiao;Haobo Xu;Xiaoming Chen;Yujie Wang;Yinhe Han;
      Pages: 155 - 158
      Abstract: Multiply and accumulate (MAC) composed of a set of multipliers and one reduction dominates the latency and power of convolutional neural network (CNN) accelerators. Existing approximate multipliers reduce latency and power at a tolerable drop in accuracy, without considering the data distribution (implicitly assuming that data are uniformly distributed). This letter discloses that practical CNNs’ activations and weights are usually Gaussian-like distributed, and the bits of quantized activations and weights are typically not with a probability of 0.5. Thus, we propose an approximate MAC unit design by taking into account the statistical features of input data, to achieve a balanced tradeoff among latency, power, and accuracy. The extensive experiments show that our proposed MAC unit design provides much higher accuracy than state-of-the-art approximate circuits, while the latency, area, and power are similar.

      Abstract: Dynamic voltage and frequency scaling (DVFS) has been the subject of extensive study for the past two decades. DVFS has been shown to dramatically reduce power consumption and thermal stress and is now routinely used in both embedded and general-purpose systems. However, DVFS research has largely focused on independently controlling voltage and frequency for individual cores. Less well studied is the case of global DVFS (GDVS), where multiple cores share the same voltage and clock. A very simple GDVS heuristic is presented in this letter; it is lightweight and effectively exploits task profiling information to appropriately sequence task executions. Simulation studies show its effectiveness.
