【摘要】 在常规的数字签名方案中,密钥的管理由一个权威认证机构负责,系统的正常运行以该机构的诚实、可靠为前提,系统极易遭受主动攻击和假冒攻击。为此,我们提出了基于自证明公钥认证的数字签名方案,有效地抵制了这一安全漏洞,提系统处理效率。更多还原

【Abstract】 A basic presumption of the conventional digital signature is that the authorities should be reliable enough to be responsible for the public key management. Thus, the system is vulnerable to the active counterfeit attacks. A digital signature scheme based on self- certified public key authentication is proposed to resist such security flaws and to improve the system’s efficiency.更多还原
