Abstract: Techniques for tamper detection of a memory module having non-volatile memory devices resident on a printed circuit board (PCB) by circuitry of a controller also resident on the PCB. Examples include determining resistance values of a character pattern sprayed on a side of a cover facing the non-volatile memory devices using conductive ink following first and second boots of the memory module and asserting a bit of a register to indicate tampering of the memory modules based on a comparison of the resistance values. Tamper policy actions may be initiated based on detection of tampering.

Abstract: A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

Abstract: Tamper-respondent assemblies and methods of fabrication are provided which include at least one tamper-respondent sensor and a detector. The at least one tamper-respondent sensor includes conductive lines which form, at least in part, at least one tamper-detect network of the tamper-respondent sensor(s). In addition, the tamper-respondent sensor(s) includes at least one interconnect element associated with one or more conductive lines of the conductive lines forming, at least in part, the tamper-detect network(s). The interconnect element(s) includes at least one interconnect characteristic selected to facilitate obscuring a circuit lay of the at least one tamper-detect network. In operation, the detector monitors the tamper-detect network(s) of the tamper-respondent sensor(s) for a tamper event.

Abstract: An apparatus comprises a plurality of conductive elements arranged within at least a first conductive layer and a dielectric layer comprising a plurality of microcapsules. The first conductive layer is arranged on a first side of the dielectric layer. The apparatus further comprises monitoring circuitry coupled with the plurality of conductive elements and configured to detect a change in an electrical parameter for at least a first conductive element of the plurality of conductive elements. The change in the electrical parameter indicates a physical intrusion of the dielectric layer that causes a rupture of one or more microcapsules of the plurality of microcapsules.

Abstract: A dynamic transaction card that is manufactured using conductive plastic jumpers that will dissolve when in contact with a solvent used to tamper with the dynamic transaction card. Internal components of a dynamic transaction card may be manufactured using a synthetic or semi-synthetic organic material, such as, for example, plastics. These materials may be conductive to provide functionality to a dynamic transaction card, such as a connection between an integrated circuit and other card components such that when the materials dissolve, the connections are broken and the dynamic transaction card may be inactive due to the loss of various connections.
