Information technology security technology entity authentication
Part 5. Mechanisms using zero-knowledge technology
1 range
This part of GB/T 15843 details three entity authentication mechanisms using zero-knowledge techniques. All in GB/T 15843
The mechanisms described in this section all provide one-way authentication. These mechanisms are constructed using the principle of zero knowledge, but are strictly based on Appendix A.
Righteousness, the choice of all parameters, these mechanisms are not zero-knowledge themselves.
The first mechanism is called an identity-based mechanism. A trusted accreditation body provides private endorsement information for each claimant.
The information is calculated as a function of the claimant's identification data and the authorized institution's private key.
The second mechanism is called a certificate-based mechanism based on the use of discrete logarithms. Every claimant has a pair of publics for this mechanism
Open key and private key pair. The verifier of each claimant must have a trusted copy of the claimant’s public verification key;
The method of taking is beyond the scope of this standard, but it can be obtained through the distribution of certificates signed by trusted third parties.
The third mechanism is called a certificate-based mechanism based on the use of asymmetric cryptosystems. Every claimant has a pair for non-pair
The public key and private key pair of the encryption system. The verifier of each claimant must have the claimant’s public verification key
Trusted copy; the method of obtaining it is beyond the scope of this standard, but can be distributed through a certificate signed by a trusted third party.
