| Abstract: | 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. |
