Cryptanalysis of the Two-Dimensional Circulation Encryption Algorithm

EURASIP Journal on Advances in Signal Processing volume 2005, Article number: 968795 (2005) Cite this article

Abstract

We analyze the security of the two-dimensional circulation encryption algorithm (TDCEA), recently published by Chen et al. in this journal. We show that there are several flaws in the algorithm and describe some attacks. We also address performance issues in current cryptographic designs.
