Self-certified Blind Signcryption Scheme Based on ECC
Yi Wei · Jisuanji gongcheng · 2010
Elliptic Curve Cryptography(ECC) is based on the hardness of elliptic curve discrete logarithm problem,and it has higher security and shorter operands than other cryptographs. Aiming at these advantages,this paper designs a self-certified blind signcryption scheme based ECC. Legal user blinds the signed message,and it is difficult for illegal user to analyze the plaintext without blind factor. This scheme can prevent the illegal user from repudiation,forging and juggling the message,and it satisfies correctness,blindness,enforceability and intractability for blind signcryption.
