In this paper, a SET pulse width model derived from SPICE simulations is presented. The model expresses the SET pulse width in terms of particle’s LET, target inverter’s drive strength and supply voltage. A bias-dependent current source was employed to model the SET current pulse, thus providing better accuracy compared to similar approaches based on the widely used double-exponential current source. Evaluation was done for standard inverters in IHP’s 130 nm CMOS process. The average relative error of the proposed model with respect to the results from SPICE simulations is below 10 % for analyzed cases.

Computer Standards and Interfaces 65, 1 (2019)
DOI: 10.1016/j.csi.2019.01.005, (e-balance)
This paper presents a data-centric middleware responsible for real-time communication and data storage in smart grids. The middleware offers a high level programming model that provides ways of storing/getting information from/to the grid and encrypts messages thus providing a secure message exchange. The design has taken into account the heterogeneity of devices, software platforms and stakeholders involved in this kind of scenario. A modular vision is followed in such a way that middleware components can be easily adapted to different platforms and a simple data interface is provided by means of REST (Representational State Transfer) web services and a high level asynchronous API. The middleware is currently being used in the context of a European project (e-balance) where soft real-time requirements, security and low capacity devices are some of the requirements in an example Cyber-physical System (CPS). The demonstration scenarios are detailed in this paper together with the validation tests that show that the use of this programming abstraction is feasible.

(7) Design of Robust Quantizers for Low-Bit Analog-to-Digital Converters for Gaussian Source
M.R. Dincic, Z.H. Peric, D.B. Denic, Z. Stamenkovic
Journal of Circuits, Systems, and Computers (JCSC) 28(1), 1940002 (2019)
DOI: 10.1142/S0218126619400024
This paper considers the design of robust logarithmic µ-law companding quantizers for the use in analog-to-digital converters in communication system receivers. The quantizers are designed for signals with the Gaussian distribution, since signals at the receivers of communication systems can be very well modeled by this type of distribution. Furthermore, linearization of the logarithmic µ-law companding function is performed to simplify hardware implementation of the quantizers. In order to reduce energy consumption, low-resolution quantizers are considered (up to 5 bits per sample). The main advantage of these quantizers is high robustness - they can provide approximately constant SNR in a wide range of signal power (this is very important since the signal power at receivers can vary in wide range, due to fading and other transmission effects). Using the logarithmic µ-law companding quantizers there is no need for using AGC (automatic gain control), which reduces the implementation complexity and increases the speed of the analog-to-digital converters (ADC) due to the absence of AGC delay. Numerical results show that the proposed model achieves good performances, better than a uniform quantizer, especially in a wide range of signal power. The proposed low-bit ADCs can be used in MIMO and 5G massive MIMO systems, where due to very high operating frequencies and a large number of receiving channels (and consequently a large number of ADCs), the reduction of ADC complexity and energy consumption becomes a significant goal.

DOI: 10.1109/ACCESS.2019.2907156, (fast spot)
In this paper, we show our 165 Gbps data link layer processor for wireless communication in the terahertz band. The design utilizes interleaved Reed-Solomon codes with dedicated link adaptation, fragmentation, aggregation, and hybrid-automatic-repeat-request. The main advantage is the low chip area required to fabricate the processor, which is at least 2 times lower than the area of low-density parity-check decoders. Surprisingly, our solution loses only ~1 dB gain when compared to high-speed low-density parity-check decoders. Moreover, with only 2.38 pJ/bit of energy consumption at 0.8V, one of the best results in the class of comparable implementations has been achieved. Alongside, we show our vision of a complete 100 Gbps wireless transceiver, including radio frequency frontend and baseband processing. For the baseband realization, we propose parallel sequence spread spectrum and channel combining at the baseband level. Challenges to high-speed wireless transmission at the terahertz band are addressed as well. To the authors’ best knowledge, it is one of the first data link layer implementations that deal with a data rate of ≥100 Gbps.

(maximumMIMO)
In this paper, we show a novel algorithm for strong line-of-sight (LoS) multiple-input-multiple-output (MIMO) channel equalization. With optimally spaced antennas under specific arrangements, the LoS channels can be made spatially orthogonal. In practice, antenna displacements are expected. Conventional algorithms like zero-forcing (ZF) do not consider the special properties of the LoS MIMO channel and result in high complexity. We show that the LoS MIMO channel can be factorized into a product of three matrices. Thereby, the two diagonal matrices at the outer product positions are the most varying terms and should be compensated dynamically. Being a good tradeoff between complexity and robustness, the proposed sequential channel equalization is applied in a reverse order of the factorization. The algorithm can be applied to LoS MIMO systems with uniform linear or rectangular arrays, which are making use of digital or analog equalization. By considering the usage of the Winograd butterfly and Butler matrices, the number of multiplications in both digital and analog implementations of the proposed solution is increasing approximately linearly with respect to the number of antennas, while the complexity of the state-of-the-art designs grows quadratically. As found numerically and verified experimentally, the proposed method performs nearly as well as the ZF-based algorithms with near-optimal arrangements, while having significantly lower complexity.

(22) Noise Performance of Orthogonal RF Beamforming for THz Radio Communications

DOI: 10.1109/CCWC.2019.8666546, (WORTECS)
Ultra wide-band terahertz (THz) radio links are envisaged for high throughput and low latency radio communication from server to virtual reality (VR) head mounted display (HMD). Orthogonal radio frequency (RF) beamforming is suitable for such extremely high frequency radio links owing to the propagation characteristics. For RF beam training, the transmit-receive (Tx-Rx) beam combination yielding maximum received signal strength indication (RSSI) is selected. For typical complex signals employed in IQ architecture receivers,  RSSI is Rayleigh distributed. Receiver noise can cause false beam selections manifesting in communication rate loss. In this paper, analytically derived closed-form expressions and preliminary Monte Carlo (MC) simulation results for such noise performance evaluation have been presented.

With the growing number of wireless devices in the IoT, maintenance and management of these devices becomes a key issue. In particular, the capability for wireless code updates is a must in order to fix security issues, software bugs, and extend firmware functionality in the field. Thereby, code update mechanisms in WSNs have to deal with limited resources. On top of that, the capability of wireless code updates also opens new security vulnerabilities. The chapter presents a general overview about various approaches for OTA code update techniques for WSNs. Distribution protocols as well as techniques for improving the reliability of these updates are presented, too. Based on this overview about existing OTA techniques their security flaws are presented along with some existing attacks and possible countermeasures. Therefore, a classification of security threats is presented and which of them can be used more easily with code update functionality. Finally the state of the art countermeasures are presented and compared if they secure the mentioned weakened security objectives.

Implementing cryptographic algorithms in a tamper resistant way is an extremely complex task as the algorithm used and the target platform have a significant impact on the potential leakage of the implementation. In addition the quality of the tools used for the attacks is of importance. In order to evaluate the resistance of a certain design against electromagnetic emanation attacks – as a highly relevant type of attacks – we discuss the quality of different electromagnetic (EM) probes as attack tools. In this paper we propose to use the results of horizontal attacks for comparison of measurement setup and for determining the best suitable instruments for measurements. We performed horizontal differential electromagnetic analysis (DEMA) attacks against our ECC design that is an im-plementation of the Montgomery kP algorithm for the NIST elliptic curve B-233. We experimented with 7 different EM probes under same conditions: attacked FPGA, design, inputs, measurement point and measurement equipment were the same, excepting EM probes. The used EM probe influences the success rate of performed attack significantly. We used this fact for the comparison of probes and for determining the best suitable one.
