Abstract:Identity based(ID-based) public key cryptosystem gives an efficient alternative for key management as compared to certificate based public key setting. Proxy signature is a signature scheme that an original signer delegates his/her signing capability to a proxy signer, and then the proxy signer creates a signature on behalf of the original signer. Due to various application of the bilinear pairings in cryptography, many identity based signature scheme have been proposed. In this paper, we propose an identity b… Show more
