Abstract
An encrypting transponder provides data security for transmissions between a terminal and a remote computer, network or terminal. The transponder provides positive user and terminal identification before access to a remote computer file is permitted, and further provides for secure message authentication during the course of data transmission. The transponder is passive and operates in response to interrogation from a remote host computer, thus making it useful with many different operating system and hand-shake protocols.
