Generate random image-key using hash technique

Abstract EN

Random image is very useful to be used as a source for clipping randomness session keys in cryptography.

In this paper a new algorithm is proposed to generate random image .The random image is generated by mixing initialization vector with normal digital image ; the mixing process is applied in the same way as HASH technique.

A special cryptography algorithm for generating random numbers is used to generate initialization vector.

This proposed algorithm is capable of generating random image that can meet security requirements of cryptographic algorithms.
