Cryptanalysis of the Compression Function of SIMD [PDF]
, 2011 SIMD is one of the second round candidates of the SHA-3 competition hosted by NIST. In this paper, we present the first attack for the compression function of the reduced SIMD-256 and the full SIMD-512 (the tweaked version) using the modular difference method. For SIMD- 256, we give a free-start near collision attack on the compression function reduced

Function-on-Function Linear Regression by Signal Compression
Journal of the American Statistical Association, 2017 We consider functional linear regression models with a functional response and multiple functional predictors, with the goal of finding the best finite dimensional approximation to the signal part of the response function. Defining the integrated squared correlation coefficient between a random variable and a random function, we propose to solve a ...

On Network Functional Compression [PDF]
IEEE Transactions on Information Theory, 2014 In this paper, we consider different aspects of the network functional compression problem where computation of a function (or, some functions) of sources located at certain nodes in a network is desired at receiver(s). The rate region of this problem has been considered in the literature under certain restrictive assumptions, particularly in terms of ...

Construction and Analysis of SHA-256 Compression Function Based on Chaos S-Box
IEEE Access, 2021 To further improve the security of SHA-256, a compression function construction scheme based on chaotic S-box is proposed. Through the reasonable design of the iteration mode and using the nonlinearity, confusion, and anti-difference of chaotic S-box ...

Compressed Static Functions with Applications [PDF]
Proceedings of the Twenty-Fourth Annual ACM-SIAM Symposium on Discrete Algorithms, 2013 Given a set of integer keys from a bounded universe along with associated data, the dictionary problem asks to answer two queries: membership and retrieval. Membership has to tell whether a given element is in the dictionary or not; Retrieval has to return the data associated with the searched key.

Compressing Functional Tests for Microprocessors [PDF]
14th Asian Test Symposium (ATS'05), 2005 In the past, test data volume reduction techniques have concentrated heavily on scan test data content. However, functional vectors continue to be utilized because they target unique defects and failure modes. Hence, functional vector compression can help alleviate the cost of functional test. Scan vector compression techniques are generally unsuitable
