In this paper we examine one of the recently proposed chaotic image encryption algorithms, based on chaotic map lattices (CML). We also study and examine another algorithm that could satisfy expectations of efficiency and security in the case of digital colour image encryption. The proposed algorithm provides more security and secrecy to the colour digital images as compared to the security provided by the existing CML based algorithm suggested by Pisarchik. At the end, we show the results of a security analysis and a comparison of both schemes.
