一种基于身份的广义签密方案
An Identity-based Generalized Signcryption Scheme
摘要
Abstract
For meeting the requirements of security in unstable network environment,generalized signcryption is proposed. It has flexible features,and can achieve signcryption,encryption and signature within one cryptographic module. In order to improve the computational efficiency and security,analysis of the proposed schemes,a new identity-based generalized signcryption program is put forward. The se-curity of this scheme is proved from all aspects,then it is in contrast with the proposed schemes which has high computational efficiency. An application example of the scheme is given and the process of applying the program is described in mail system. The results show that the new scheme reduces the numbers of computation of the pairing and scalar multiplication.关键词
