Editing On the Security of the Yi-Tan-Siew Chaotic Cipher

Title: On the Security of the Yi-Tan-Siew Chaotic Cipher

Research Question: Can the Yi-Tan-Siew chaotic cipher withstand cryptanalytic attacks?

Methodology: The researchers analyzed the Yi-Tan-Siew chaotic cipher and proposed a comprehensive analysis on its security. They suggested two types of attacks: differential chosen-plaintext attack and differential chosen-ciphertext attack. They also pointed out some design flaws in the cipher.

Results: The researchers found that the sub-key K can be removed by the suggested attacks, and the security of the cipher is independent of the chaotic map but depends on the mixture of three operations from different algebraic groups. They also noted that the noise vectors do not have a uniform distribution, limiting the value of the sub-key α. Moreover, the sub-key β should not be part of the secret key due to its poor contribution to the cipher's security.

Implications: The findings indicate that the Yi-Tan-Siew chaotic cipher may not be as secure as previously thought. The researchers' suggestions for attacks and design flaws can help improve the security of similar ciphers in the future. The results also emphasize the importance of cryptanalytic studies in evaluating the security of chaotic ciphers.
