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.

Abstract: A secure electronic data module containing a monolithic semiconductor chip of the type having a memory that is protected by a combination of hardware and software mechanisms such that unauthorized access to the data stored in the memory is prevented. The monolithic semiconductor chip comprises a plurality of solder bumps for attaching the chip to a substrate that my be a printed circuit board or another chip; a multi-level interlaced power and ground lines using minimum geometries; and a detection circuit block for detecting an external trip signal that my be produced by a prespecified change in an operating condition brought on by unauthorized accessing, or an internal trip signal that may be produced by shorting of power and ground lines or by a change in an oscillator's frequency, also associated with or appurtenant to unauthorized accessing of the secure memory.
