Authenticated encryption scheme with message recovery based on ECC
Jianhua Ge · Computer Engineering and Applications Journal · 2009
A new digital signature encryption scheme with message recovery based on elliptic curve cryptography is presented. Shao proposes an improved digital signature scheme with message recovery based on ECC.It has overcome the weakness of Tzeng’s scheme that lacks nonrepudiation and forward security.But Shao’s algorithm which tries to achieve the hash value of a point on elliptic curve and an integer,cannot be realized.It has improved the weakness of Shao’s scheme.Furthermore,the new scheme appends time stamp to signature,and it can resist against replay attack.
