Evaluating Two Determinants
Shujun Li
This article evaluates the determinants of two classes of special matrices, which are both from a number theory problem. Applications of the evaluated determinants can be found in…
Permutation Polynomials modulo m
Shujun Li
This paper mainly studies problems about so called "permutation polynomials modulo ", polynomials with integer coefficients that can induce bijections over Z_m={0,...,m-1}. The…
On the security of the Yen-Guo's domino signal encryption algorithm (DSEA)
Chengqing Li, Shujun Li, Der-Chyuan Lou +1
Recently, a new domino signal encryption algorithm (DSEA) was proposed for digital signal transmission, especially for digital images and videos. This paper analyzes the security o…
Estimating short-time period to break different types of chaotic modulation based secure communications
Gonzalo Alvarez, Shujun Li
In recent years, chaotic attractors have been extensively used in the design of secure communication systems. One of the preferred ways of transmitting the information signal is bi…
On the Security of the Yi-Tan-Siew Chaos-Based Cipher
Shujun Li, Guanrong Chen, Xuanqin Mou
This paper presents a comprehensive analysis on the security of the Yi-Tan-Siew chaotic cipher proposed in [IEEE TCAS-I 49(12):1826-1829 (2002)]. A differential chosen-plaintext at…
Baptista-type chaotic cryptosystems: Problems and countermeasures
Shujun Li, Guanrong Chen, Kwok-Wo Wong +2
In 1998, M. S. Baptista proposed a chaotic cryptosystem, which has attracted much attention from the chaotic cryptography community: some of its modifications and also attacks have…
