Abstract
From the perspective of optical cryptanalysis, we propose a method of chosen-plaintext attack against the optical encryption scheme based on joint transform correlator (JTC) architecture. By implementing this attack, an opponent can access the encryption key with the help of the pre-knowledge of a special chosen plaintext and the corresponding ciphertext. It indicates that the optical encryption scheme based on the JTC architecture is vulnerable to chosen-plaintext attack, even though introducing a nonlinear operation into the encryption transform. The validity of this attack is verified by numerical simulations.
