摘要：This paper first introduces the foundational knowledge on the digital signature and digital signcryption. Based on the comprehensive analysis on existing digital signature scheme and signcryption scheme, to reduce the inverse operation in the signature validation, this paper proposes an improved digital signcryption algorithm based on the directional ellipse curve by using difficulty in solving the discrete logarithm of the ellipse curve. The direction indicates that only specified receiver can decrypt the signcryption. The experiment indicates that this improved algorithm can speed up computing speed and can achieve remarkable optimization effect.
