SYSTEM AND METHOD FOR SECURE TWO-FACTOR AUTHENTICATED ID-BASED KEY EXCHANGE AND REMOTE LOGIN USING AN INSECURE TOKEN AND SIMPLE SECOND-FACTOR SUCH AS A PIN NUMBER

摘要

A system and method of authenticated ID-based key exchange and remote login with insecure token and PIN number can provide an authenticated key agreement protocol based on an elliptic curve bilinear type-3 pairing. A server acts as an Authentication Service to Clients and a Trusted Authority (TA) issues identity based secret numbers to Clients and Authentication Services. Included in the system and method is the capability for the Client to split their secret number into two parts, a Client selected PIN number, and the larger number, the Token.
