Title:
TWO-FACTOR COMBINED PUBLIC KEY GENERATION AND AUTHENTICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2009/143713
Kind Code:
A1
Abstract:
A two-factor combined public key system and authentication method for compounding the identification key and random key are provided. The identification key is generated by using the number-sequence generated by the user identification to select and combine the seed key set; the random key is generated based on the one-way function principle that usual common public keys rely on. The many compound modes of the random key and the identification key not only can meet the requirement of the centralized management, but also can endow the user with the exclusive right for the private key. The authentication system based on this key generation method has the both advantages that the identification authentication does not need the certificate proof of the third party and the random private key of the common public key is randomized and privatized highly. The system can be widely applied in all kinds of scale, especially super-large scale public system authentication, which includes the fields of credibility access, credibility loading, electronic banking, credibility transaction, and credibility logistics etc..
