Abstract:
A proxy blind signature scheme is a special form of blind signature which allows a designated person called proxy signer to sign on behalf of two or more original signers without knowing the content of the message or document. It combines the advantages of proxy signature and blind signature scheme and satisfies the security properties of both proxy and blind signature scheme. This paper describes an effcient simple proxy blind signature scheme. The security of the scheme is based on Elliptic Curve Discrete Logarithm Problem(ECDLP). ECC offers security equivalent to RSA and DSA while using far smaller key sizes. The benefits of this higher-strength per-bit include higher speeds, lower power consumption, bandwidth savings, storage effciencies, and smaller certificates. This can be implemented in low power and small processor mobile devices such as smart card, PDA etc.
