A New Idea in Cryptography for Information Security

In this paper, we introduce a new hash structure. It is suggested to have a pre-processing step on the input message by code transformer. we also show that our suggested structure has a suitable security against different attacks. this suggested hash structure can be use for the multi-purpose goals similar Digital signature, Message Digest, Passwords Saving, Message Authentication, Random Bits Generation.
