Method for distributing and authenticating public keys using time ordered exchanges

A method to exchange and authenticate public cryptographic keys between parties that share a common but secret password. The parties exchange public keys, where the public keys are accompanied by hashed values based on the keys, the password, and random numbers. Each party then encrypts its random n...

Zusammenfassung:	A method to exchange and authenticate public cryptographic keys between parties that share a common but secret password. The parties exchange public keys, where the public keys are accompanied by hashed values based on the keys, the password, and random numbers. Each party then encrypts its random number using the public key of the other party, and the encryptions are exchanged. Based on the received encryptions and the known password, each party then re-computes the hashed value received from the other party, and compares the re-computed hashed value with the received hashed value. If the two are the same, the public key that accompanied the hashed value is judged authentic.
