Abstract: We propose collision in asymmetric cryptosystem based on phase-truncated Fresnel transform. An arbitrary image can be generated from ciphertext or watermark embedded in a host image with the help of phase retrieval algorithm. Computer simulation results support the idea of the proposed collision.
