Anti-tamper for JTAG boundary scan ports

LIT Proposed development of a Secure Test/Programming Interface (STPI) that provides both Access Control and Tamper Detection. Phase I achievements include: Probe/Connection Detect Low Component Impact Through-the-System Protection Around-the-System Protection Layered Authentication In Phase II, LIT will advance the STPI AT technology by developing STPI product concepts and by demonstrating the use of these AT products on tactical hardware. The goals of this approach are to: Develop straightforward methods for incorporating LIT STPI technology into tactical systems. Provide multiple options for incorporating LIT STPI technology. Improve the LIT STPI through prototyping, analysis, and independent test and evaluation. LIT produced a functional prototype in Phase I that demonstrated all the proposed Technical Objectives. Because of the success of Phase I, LIT plans to incorporate STPI into tactical hardware for demonstration, test, and analysis in Phase II. LMCO MS2 is identifying candidate systems for use in STPI demonstrations. Several candidate systems have already been identified that contain IP and Critical Technology that requires effective protection from unauthorized access.
