The pervasiveness of wireless communication recently gave mobile ad hoc networks (MANET) a significant researcher's attention, due to its innate capabilities of instant commu...
In this paper we study the substitution-permutation network (SPN) on which AES is based. We introduce AES∗ , a SPN identical to AES except that fixed S-boxes are replaced by ran...
A family of permutations in Sn is k-wise independent if a uniform permutation chosen from the family maps any distinct k elements to any distinct k elements equally likely. Effici...
Watermark resistance to geometric attacks is an important issue in the image watermarking community. Most countermeasures proposed in the literature usually focus on the problem of...
We study the phenomenon of cognitive learning from an algorithmic standpoint. How does the brain effectively learn concepts from a small number of examples despite the fact that e...
