Abstract
A system and method for verifying the identification of a user and securely establishing an encryption key for a communication between the user and a verifying entity, such as a bank, which makes use of the numeric value of the user's personal identification number (PIN) known only to the user and the bank and resolves the man-in-the-middle problem. The system and method replaces a public parameter with the customer's PIN to provide an encryption mechanism that is less complex than existing protocols. Use of the protocol enables new products and improvement of existing products using a service access device and service access device interface, including, for example, self-service terminals.
