Cryptanalysis of the Two-Dimensional Circulation Encryption Algorithm
Christophe De Cannière, Joseph Lano, Bart Preneel · EURASIP Journal on Advances in Signal Processing · 2005
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.
