Deterministic Identity Based Signature Scheme and Its Application for Aggregate Signatures
The revolutionary impact offered by identity based cryptography is phenomenal. This novel mechanism was first coined by Adi Shamir in 1984. Since then, several identity based signature schemes were reported. But surprisingly, none of the identity based signature scheme is having the property of determinism and does rely on bilinear pairing. The authors think positively in answering this long standing question of realizing deterministic identity based signature in composite order groups and they succeed in developing a signature scheme based on RSA assumption and is deterministic. It is indeed helpful in devising variants of signature primitive.
