Authentication method for telephone subscriber identity

Abstract

This invention relates to an authenticating method for telephone subscriber identities, which sets a system for distinguishing identity of a phone call and short message of a telephone subscriber, judges if the caller or dispatcher of the short message is allowed to dial or send the short message to the user including distribution of identity cards and identitity differentiation based on it to judge the validity of the incoming and the short message: 1, applying a public key algorithm to generate an authentication code: Kpub and Kpri needed by the Kpub algorithm are generated by Krooi set by each phone subscriber, 2, when callerB dials the phone of subcriberA, the system first of all gets phone numberNB of B and looks it up in an access list of A and triggers the identity authentication process, 3, differentiating identity based on the authentication card.
