Self-certified Signcryption Scheme Based on Elliptic Curve
Zhicang Wang · Microcomputer Information · 2010
On the basis of analysis of elliptic curve cryptosystem (ECC),a new selfcertified sigcryption scheme based on elliptic curve is designed under the hardness of elliptic curve discrete logarithm problem. In the new scheme,no public key certificate is required for validating the public key; the user generates his own private key; however,be able to guarantee the confidentiality and Authenticity simutaneously when the message is transmitted. Compared with the previous schemes,the proposed can get higher security with lower cost,and it has good practicability.
