Abstract
This paper analyzes the security of a new multistage encryption system (MES) recently proposed in ISCAS´2004. It is found that MES is insecure against a differential chosen-plaintext/ciphertext attack. Experiments are given to support the proposed attack. It is also pointed out that the security of MES against brute-force attacks is not sufficiently high.
