摘 要: 针对电子邮件安全问题,提出一种基于身份密码体制的无可信第三方数字签名方案.该方案避免了可信第三方伪造系统内所有用户签名的问题,运行分析表明,该方案安全有效,适合在电子邮件系统中使用. To solve the security problem in the e-mail trusted PKG was proposed. This scheme was based on system, a new scheme of identity-based signature without a identity-based cryptography. In this scheme PKG, could not forge the signature of anyone in the e-mail system. The simulation results demonstrate that this scheme is safe, efficient and suitable for the e-mail system, and the performance is batter in operation efficiency.
