Abstract
By applying the concepts of double threshold technology to signcryption theory, a new double-threshold proxy signcryption scheme from bilinear pairings is proposed.In this new scheme, the first (k, n) threshold technology is adopted in the key sharing,the original signcrypter entrusts this key to n secretaries for escrow,at least k secretaries cooperate can recover the key.lt greatly reduces the risk of key-compromise.The (t, m) threshold technology is adopted in the process of proxy signcryption,it gives the right of signcryption to entrust m proxy signcrypters sharing,no less than t proxy signcryp-ters with no right can receive the correct cipher text.To a great extent, it enhances the security.Analysis shows that the scheme is secure,and it is suitable for many applications in practice.关键词
