Abstract: The present invention relates to an electronic module having at least a microprocessor and co-processor on a single integrated circuit. The electronic module can be contained in a small housing. The electronic module provides secure bidirectional data communication via a data bus. More specifically, the present invention relates to an electronic module which includes an integrated circuit comprising a microprocessor, and a co-processor adapted to handle 1,024-bit modulo mathematics primarily aimed at RSA calculations. The electronic module is preferably contained in a small token-sized metallic container. The present invention will preferably communicate via a single wire data bus which uses a one-wire protocol.
