Recently, a chaotic image encryption algorithm based on perceptron model was
proposed. The present paper analyzes 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, some other security defects are also reported.Comment: 5 page
