Design Trade-offs in Threshold Implementations

2019 26th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2019
With the expansion of the IoT and the emergence of vast amounts of remote hardware devices side-channel attacks pose a serious threat, requiring adequate protection. Among the hardware countermeasures, Threshold Implementations (TI) is one of the most used ones. It is designed to avoid the leakage of sensitive data from hardware designs.

Design and Implementation of a Parallel Markowitz Threshold Algorithm

SIAM Journal on Matrix Analysis and Applications, 2020
This paper focuses on a novel algorithm for the parallel factorization of a non-symmetric sparse matrix using a Markowitz threshold algorithm. To solve the system of linear equations $Ax = b$, where $A$ is a sparse matrix, the authors consider dense vectors $x$ and $b$.

On minimum error thresholding and its implementations

Pattern Recognition Letters, 1988
Abstract In this paper we discuss the thresholding methods [1] due to Kittler and Illingworth. Two methods are suggested in [1], namely, 1) minimizing a criterion function aand 2) iterative search of the minimum error threshold. We have tested the two methods.

Thresholding implemented in the frequency domain

IEEE Transactions on Image Processing, 2001
Image processing procedures are usually carried out in the spatial domain where the images are acquired and presented/utilized. The linear nature of the Fourier transform allows only those operations that are linear to be mapped into the frequency domain.

Review of Capacitive Threshold Gate Implementations

2003
This is an in-depth survey paper on capacitive hardware implementations of threshold logic gates. The different VLSI solutions include the switched capacitor and the floating gate and their variations. It will be shown how the distinct original proposals from both categories have evolved to become quite similar.

On Non-Completeness in Threshold Implementations

Proceedings of ACM Workshop on Theory of Implementation Security Workshop, 2019
In this note we study non-completeness, the key property of Threshold Implementations (TIs). TIs have proved to be a popular method for mitigating side-channel leakage of sensitive information in hardware implementations of cryptographic algorithms. In particular, we provide a reformulation of non-completeness in terms of set coverings with constraints,

VLSI implementations of threshold logic- a comprehensive survey

IEEE Transactions on Neural Networks, 2003
This paper is an in-depth review on silicon implementations of threshold logic gates that covers several decades. In this paper, we will mention early MOS threshold logic solutions and detail numerous very-large-scale integration (VLSI) implementations including capacitive (switched capacitor and floating gate with their variations), conductance ...

CMOS Implementation of Generalized Threshold Functions

2003
Threshold Logic (TL) gates can evaluate any linearly separable function via the computation of a weighted sum over the input variables. In this paper we generalize this mechanism and introduce the novel concept of k-order Generalized Threshold Logic (GTL) gates.

Uniform First-Order Threshold Implementations

2017
Most masking schemes used as a countermeasure against side-channel analysis attacks require an extensive amount of fresh random bits on the fly. This is burdensome especially for lightweight cryptosystems. Threshold implementations (TIs) that are secure against first-order attacks have the advantage that fresh randomness is not required if the sharing ...

Information Cascades and Threshold Implementation

SSRN Electronic Journal, 2019
Economic activities such as crowdfunding often involve sequential interactions, observational learning, and project implementation contingent on achieving certain thresholds of support. We incorporate endogenous all-or-nothing thresholds in a classic model of information cascade. We find that early supporters tap the wisdom of a later "gate-keeper" and
