On the Performance of Hyperelliptic Cryptosystems [PDF]
, 1999 In this paper we discuss various aspects of cryptosystems based on hyperelliptic curves. In particular we cover the implementation of the group law on such curves and how to generate suitable curves for use in cryptography. This paper presents a practical comparison between the performance of elliptic curve based digital signature schemes and schemes ...

Properties of Cryptosystem PGM [PDF]
, 2007 A cryptographic system, called PGM, was invented in the late 1970's by S. Magliveras. PGM is based on the prolific existence of certain kinds of factorization sets, called logarithmic signatures, for finite permutation groups. Logarithmic signatures were initially motivated by C. Sims' bases and strong generators.

Cryptanalysis of the CFVZ cryptosystem
Advances in Mathematics of Communications, 2007 The paper analyzes CFVZ, a new public key cryptosystem whose security is based on a matrix version of the discrete logarithm problem over an elliptic curve. It is shown that the complexity of solving the underlying problem for the proposed system is dominated by the complexity of solving a fixed number of discrete logarithm problems in the group of an ...

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field
Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.

A Generalization of Gaussian Balancing and Gaussian Balancing‐Lucas Numbers With Applications
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.In this paper, we study a generalization of Gaussian balancing and Gaussian Lucas‐balancing numbers, we find their generating functions, Binet formulas, related matrix representation, and many other properties. Also, we provide some applications in cryptography.

Cryptanalysis of the Square Cryptosystems [PDF]
, 2009 Following the cryptanalyses of the encryption scheme HFE and of the signature scheme SFLASH, no serious alternative multivariate cryptosystems remained, except maybe the signature schemes UOV and HFE*** ***. Recently, two proposals have been made to build highly efficient multivariate cryptosystems around a quadratic internal transformation: the first ...

Strengthening McEliece Cryptosystem [PDF]
, 2000 McEliece cryptosystem is a public-key cryptosystem based on error-correcting codes. It constitutes one of the few alternatives to cryptosystems relying on number theory. We present a modification of the McEliece cryptosystem which strengthens its security without increasing the size of the public key.

Cryptanalysis of the TTM Cryptosystem [PDF]
, 2000 In 1985 Fell and Diffie proposed constructing trapdoor functions with multivariate equations [11]. They used several sequentially solved stages that combine into a triangular system we call T. In the present paper, we study a more general family of TPM (for "Triangle Plus Minus") schemes: a triangular construction mixed with some u random polynomials ...
