A Signature Scheme with Message Recovery Based on Elliptic Curves
Yuanping Kan · Computer Engineering and Science · 2010
In accordance with the concept of digital signature and the elliptic curve cryptosystem,this paper puts forward a signature scheme with message recovery based on elliptic curves. Analysis shows that the scheme realizes digital signature,and its security equals finding the solution to a discrete logarithm problem. Moreover,it bears the function of identifying the sender and the recipient of the message. Compared with the scheme proposed by paper [4],the presented scheme has no inverse operation and less calculation of the point multiplication on the elliptic curve,thus simplifying the computing complexity and optimizing the performance.
