On minimum error thresholding and its implementations
Pattern Recognition Letters, 1988Abstract 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, 2001Image 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.

Design and Implementation of a Parallel Markowitz Threshold Algorithm
SIAM Journal on Matrix Analysis and Applications, 2020We develop a novel algorithm for the parallel factorization of an unsymmetric sparse matrix using a Markowitz threshold algorithm. Our algorithm uses a significant extension of a maximum independent set algorithm of Luby to select a block of independent pivots in parallel. We then use this block to update the matrix again in parallel.

On Non-Completeness in Threshold Implementations
Proceedings of ACM Workshop on Theory of Implementation Security Workshop, 2019In 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,

Affine Equivalence and Its Application to Tightening Threshold Implementations [PDF]
Lecture Notes in Computer Science, 2016 Motivated by the development of Side-Channel Analysis SCA countermeasures which can provide security upi¾?to a certain order, defeating higher-order attacks has become amongst the most challenging issues. For instance, Threshold Implementation TI which nicely solves the problem of glitches in masked hardware designs is able to avoid first-order ...

CMOS Implementation of Generalized Threshold Functions
2003Threshold 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.

Threshold Implementations in Industry
Proceedings of the 2016 ACM Workshop on Theory of Implementation Security, 2016Implementing efficient countermeasures against side-channel attacks is a challenge since two decades. Especially in hardware, many masking countermeasure implementations failed due to first-order leakages caused by glitches or other effects such as early evaluation and unbalanced routing.

Dividing the threshold: Multi-probe localized EM analysis on threshold implementations
2018 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2018Cryptographic implementations typically need to be secured to retain their secrets in the presence of attacks. As a countermeasure to prevent side-channel attacks, threshold implementations are a commonly encountered concept. They resemble a multi-party computation, where the value is split in independent shares and processed separately.

A JCA-based implementation framework for threshold cryptography
Seventeenth Annual Computer Security Applications Conference, 2005The Java Cryptography Architecture, JCA in short, was created to allow JCA-compliant cryptography providers to be plugged into a JCA-aware application at run time. This configurable feature makes JCA widely used and assures its success. However, the public key cryptographic service interfaces defined by JCA are based on the conventional public key ...

Design and implementation of a sub-threshold BFSK transmitter
2009 10th International Symposium on Quality of Electronic Design, 2009Power Consumption in VLSI circuits is currently a major issue in the semiconductor industry. Power is a first order design constraint in many applications. However, a growing class of applications need extreme low power but do not need high speed. Sub-threshold circuit design can be used for these applications.
