Construction of the One-Off Public Key Based on Identity
一种基于身份一次性公钥的构造

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 user’s anonymity and the disconnection among the user’s actions. And TC can reveal the user’s identity to preventing the user committing when occasion requires.
