We construct a functional encryption scheme secure against an a-priori bounded polynomial number of collusions for the class of all polynomial-size circuits. Our constructions req...
HTTP session-id’s take an important role in almost any web site today. This paper presents a cryptanalysis of Java Servlet 128-bit session-id’s and an efficient practical predi...
We study cryptographic attacks on random Feistel schemes. We denote by m the number of plaintext/ciphertext pairs, and by k the number of rounds. In their famous paper [3], M. Luby...
KISS (‘Keep it Simple Stupid’) is an efficient pseudo-random number generator originally specified by G. Marsaglia and A. Zaman in 1993. G. Marsaglia in 1998 posted a C versio...
In this paper, we propose a mutual authentication scheme using nonce variable instead of Mac address and accompanying with token updates to improve the functionality. Lee et al. (2...
