Abstract: A data processing system, which is particularly useful for carrying out modular multiplication, especially for cryptographic purposes, comprises a plurality of independent, serially connected processing elements which are provided with data in a cyclical fashion via a control mechanism that is capable of transferring data from a set of registers to earlier ones in the series of the serially connected processing elements, at the end of a predetermined number of cycles.

Abstract: In a communications channel coupled to multiple duplicated subsystems, a method, interposer and program product are provided for verifying integrity of subsystem responses. Within the communications channel, a first checksum is calculated with receipt of a first response from a first subsystem responsive to a common request, and a second checksum is calculated for a second response of a second subsystem received responsive to the common request. The first checksum and the second checksum are compared, and if matching, only one of the first response and the second response is forwarded from the communications channel as the response to the common request, with the other of the first response and the second response being discarded by the communications channel.

Abstract: A method for embedding tamper proof layers and discrete components into a printed circuit board stack-up is disclosed. According to this method, a plating mask is applied on a base substrate to cover partially one of its faces. Conductive ink is then spread on this face so as to fill the gap formed by the plating mask. To obtain a uniform distribution of the conductive ink and then gel it, the conductive ink is preferably heated. A dielectric layer is applied on the conductive ink layer and the polymerization process is ended to obtain a strong adhesion between these two layers. In a preferred embodiment, conductive tracks are simultaneously designed on the other face of the base substrate to reduce thermo-mechanical strains and deformations.
