Abstract :
We suggest a systematic way to design secure password-based authentication protocols, which is the password verifier model. The method makes use of zero-knowledge interactive proof (ZKIP), which has been known not to be useful for the protection of passwords. For the proper usage of ZKIP, we introduce a specialized form of ZKIP, which has a secret coin tossing stage
