摘　　要：论文首先介绍了数字签名及数字签密的相关基础知识,在综合分析现存各类数字签名方案和签密方案的基础上,以减少签名验证过程中的求逆运算为优化目标,利用椭圆曲线离散对数问题的难解性,该文提出了一类基于有向性椭圆曲线的改进数字签密算法,有向性即只有指定的接收者才能解签密,通过实验证明,该改进算法能够加快运算速度,具有显著的优化效果。This article expounds basic information related to digital signature and digital signcryption. Based on the integrated analysis on various existing digital signature programs and signcryption programs, and utilizing the difficulty of oval curve discrete logarithmic problem, this paper proposes the improved digital signcryption algorithm on the basis of aeoplotropism ellipitc curve so as to meet the optimized target of reducing seeking inverse operation in the process of signcryption proof procedure. Aeoplotropism means only the specipient can make the signcryption. Experiments show that this improved algorithm has a significant effect of accelerating operation.
