Abstract

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.
