A. B. Orue, G. Alvarez, F. Montoya, C. Sanchez-Avila

摘要:

本文研究了一种基于蔡氏电路的混沌密码系统的安全性,并用状态控制细胞神经网络实现。结果表明,在接收机参数错误的情况下,经过不完全解码后,可以通过密文带通滤波恢复明文。它还表明,该系统的密钥空间可以显着减少缓解暴力攻击。通过分析接收机和发射机参数失配产生的译码误差,高精度地确定了系统参数。

英文摘要:

This paper studies the security of a chaotic cryptosystem based on the Chua circuit and implemented with State Controlled Cellular Neural Networks. It is shown that the plaintext can be retrieved by ciphertext band-pass filtering after an imperfect decoding with wrong receiver parameters. It is also shown that the key space of the system can be notably reduced easing a brute force attack. The system parameters were determined with high precision through the analysis of the decoding error produced by the mismatch between receiver and transmitter parameters.
