Provably Secure Self-Certified Signature Schemes with Message Recovery
To solve the key escrow problem of the identity-based cryptosystem,Girault introduced the notion of a self-certified public key,which not only eliminates the need to authenticate a public key but also solves the key escrow problem.This paper proposes a Self-Certified Signature (SCS) scheme with message recovery and two variants without using bilinear pairings:one is the authenticated encryption scheme in which only the designated receiver can verify the signature,and the other is the authenticated encryption scheme with message linkage that deals with large messages.These three SCS schemes are provably secure in the random oracle model and are more efficient than previous schemes.
