|Title:||Collision in Phase Truncation Based Asymmetric Cryptosystem in Fresnel Domain|
Rajput, S. K.
Nishchal, N. K.
|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.|
