<P>PROBLEM TO BE SOLVED: To transmit a secure message in a telecommunications system, utilizing public encryption keys. <P>SOLUTION: All authentication parameters of each of the users, including each user's decryption key about which only the user is told, are used to verify, by public key methods, the identity of a user sending a communication message. During the authentication process, encryption key for use in communications between the two users may also be generated. The generated encryption key may be a private session key. Once the initial authentication is completed, the session key can be used. Two users may use the method, to authenticate each other and generate two encryption key that is used to encrypt subsequent communication. A first encryption key is used only in the authentication process and a second encryption key is used in both the authentication process and as the key for encrypting subsequent communications. <P>COPYRIGHT: (C)2009,JPO&INPIT |
