Construction and Analysis of SHA-256 Compression Function Based on Chaos S-Box [PDF]
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 ...

Theory compression with elliptic functions [PDF]
Symposium - International Astronomical Union, 1996 Introduction of Jacobi elliptic functions in planetary, satellite and cometary problems of celestial mechanics is a transformation of variables to present the analytical theories of motion in the more compact form as compared with the traditional series in multiples of mean longitudes or mean anomalies.

Network Functional Compression [PDF]
IEEE Transactions on Information Theory, 2021 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 ...

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.
