Ambiguous Multi-Symmetric Cryptography (AMSC) that hide multiple plain-texts in a cipher same number of keys.The goal of this method is to overcome the problem of symmetric cryptography failure when the shared key is exposed.The proposed method AMSC is a cryptographic primitive that preserves plausible deniability after a cryptographic key is discovered.We evaluate AMSC in terms of security and complexity.The security analysis shows that our scheme withstands all security attack models with different knowledge of the adversary.In terms o time complexity, AMSC produces the cipher polynomial time with respect to the number and size of the plaintexts and keys.AMSC has two main applications: a) It sends multiple messages for multiple receivers through one cipher-text.b) It sends one real message and multiple decoys to defeat attacks by providing security beyond conventional brute-force bounds.For both applications, AMSC can be used to deny encryption.
