We answer the question of Reyhanitabar et al. from FSE’09 of constructing a domain extension scheme for enhanced target collisionresistant (eTCR) hash functions with sublinear ke...
In this paper we analyze the security of systems based on modular additions, rotations, and XORs (ARX systems). We provide both theoretical support for their security and practical...
In this paper, we improve the recent rebound and start-from-the-middle attacks on AES-like permutations. Our new cryptanalysis technique uses the fact that one can view two rounds ...
This paper presents new software speed records for AES-128 encryption for architectures at both ends of the performance spectrum. On the one side we target the low-end 8-bit AVR mi...

Abstract. JH, designed by Wu, is one of the 14 second round candidates in the NIST Hash Competition. This paper presents the first analysis results of JH by using rebound attack. ...
