Deciphering a novel image cipher based on mixed transformed Logistic maps [PDF]
, 2015 Since John von Neumann suggested utilizing Logistic map as a random number generator in 1947, a great number of encryption schemes based on Logistic map and/or its variants have been proposed. This paper re-evaluates the security of an image cipher based

Differential Cryptanalysis and Boomerang Cryptanalysis of LBlock [PDF]
, 2013 LBlock is a lightweight block cipher proposed in ACNS 2011. It has a 64-bit block size and 80-bit key size which is the typical parameter setting accepted by most of the recent proposed lightweight block ciphers. It has fast hardware implementation efficiency and it still remains rather secure considering the recent results and the security margin it ...

Wave-Shaped Round Functions and Primitive Groups [PDF]
, 2018 Round functions used as building blocks for iterated block ciphers, both in the case of Substitution-Permutation Networks and Feistel Networks, are often obtained as the composition of different layers which provide confusion and diffusion, and key ...
