New Message Recovery Signature Schemes and its Security
LU Jian-zhu · Mini-micro Systems · 2003
In this paper, two schemes for digital signature with message recovery are presented. The security of these schemes is based on factorization and discrete logarithms. The parameter of the signatures in the schemes are randomly selected, hence the schemes are highly security. Moreover, the key assignment of the schemes is simple, and they have better performance and lower communication costs than a previous digital signature with message recovery, therefore the schemes are practical.
