Embodiment Construction
[0042] The present invention will be further described below with reference to the drawings and embodiments, but it is not intended to limit the present invention.
[0043] The present invention integrates three technologies: blinding technology, multi-party authorization mechanism and password-based authentication mechanism. The function of blinding is to remove the dependence on the secure channel, and the function of multi-party authorization mechanism is to overcome the impact of a separate key generator on users. The escrow of the private key, based on the password authentication mechanism, is to prevent an attacker from imitating the user or a certain key generator.
[0044] The scheme of the present invention is specifically as follows:
[0045] See figure 1 The present invention provides an identity-based key generation method, the method steps are as follows:
[0046] Step A: Set system parameters; the specific implementation steps are as follows:
[0047]Step 101: Set t...
