Abstract: A forward secure short threshold proxy signature scheme from bilinear pairing is proposed by combining the concept of forward security with threshold signature from bilinear pairing.In this scheme,the key updating algorithm is used by the original signer,so the security of the proxy signature key is promoted to a higher level.The performance of the scheme is also analyzed,and it is shown that this proposed scheme is secure and effective.

Key words: bilinear pairing, forward secure, short signature, threshold signature, proxy signature
