最近，提出了一种基于感知器模型的混沌图像加密算法。本文分析了该算法的安全性，发现只需一对已知的明文/密文就可以重构出等价的密钥，并给出了数学证明和实验结果。此外，还报告了另外两个安全缺陷。
Recently, a chaotic image encryption algorithm based on the perceptron model was proposed. The present paper analyzes the security of the algorithm and finds that the equivalent secret key can be reconstructed with only one pair of known-plaintext/ciphertext, which is supported by both mathematical proof and experiment results. In addition, two other security defects are also reported.
