The mission of Anti-Tamper (AT) is to deter reverse engineering of critical military technology in order to impede technology transfer and alteration of system capability, and to prevent development of countermeasures. Weapons that are vulnerable to tampering can weaken a military advantage, shorten the expected combat life of a system, and erode technological competitiveness. AT is now required in all new military programs per the 5000-series directives from the U.S. Department of Defense (DoD).

This paper outlines the requirements of a complete AT solution and discusses specific requirements for different types of applications. It also discusses the solutions Altera offers that meet the AT requirements of the military market and explains how Altera continues to enhance AT features in current and future products.
