Abstract

In this paper, we improve the security of an id based key exposure free chameleon hashing scheme based on RSA assumption for this purpose we have contribute two random integer to compute chameleon hashing by doing so, prevent some signature from collision resistant active attack and also make it security scheme.

Keywords

Signature, Chameleon Hashing, Key Exposure, Gap Diffiehellman Group, RSA Assumption.
