摘要：In some previous research works, it has been
theoretically proven that RC5-CBC encryption algorithm behaves
as a Devaney topological chaos dynamical system. This unpredictable
behavior has been experimentally illustrated through
such sensitivity tests analyses encompassing the avalanche effect
phenomenon evaluation. In this paper, which is an extension of
our previous work, we aim to prove that RC5 algorithm can
guarantee a much better level of security and randomness while
behaving chaotically, namely when embedded with CBC mode of
encryption. To do this, we have began by evaluating the quality
of such images encrypted under chaotic RC5-CBC symmetric
key encryption algorithm. Then, we have presented the synthesis
results of an hardware architecture that implements this chaotic
algorithm in FPGA circuits.
