ABSTRACT:
The invention comprises a method for encrypting data for communication between a host computer and each of a plurality of remote terminals in a network. A method is provided for periodically generating a unique dynamic encryption key for each of said plurality of terminals using a system seed key residing only in the host computer. The dynamic encryption key generated for use by said terminal in encrypting data transmitted to said host computer and for decrypting data received from said host computer. The method includes storing at said terminal the dynamic key previously generated by said host for said terminal.
