一种基于身份一次性公钥的构造
Construction of the One-Off Public Key Based on Identity
-
摘要: 该文利用基于身份的密码系统,构造一个一次性公钥,来解决Internet通信的匿名性问题。在该系统中,用户只需由可信中心颁发一次私钥,而在每次活动时自己生成不同的公钥,通过与之对应的签名方案,在认证用户身份的同时,保证用户的匿名性和多次活动之间的不可联系性。另外,在必要时,可以联合可信中心揭示用户的真实身份,以防止用户的恶意活动。Abstract: In order to resolve the problem of Internet communication anonymity, the paper constructs one-off public key using identity-based cryptography. In this system, user only needs TC(Trust Center) issuing the private key one time, and he can generate his different public keys when uses it. So it can ensure the users anonymity and the disconnection among the users actions. And TC can reveal the users identity to preventing the user committing when occasion requires.
