Test & Evaluation

Testing for Anti-Tamper

Anti-Tamper (AT) is tested and verified during Developmental Test and Evaluation (DT&E) and Operational Test and Evaluation (OT&E). The Program Manager (PM) develops the validation plan and provides the necessary funding for the AT Verification and Validation (V&V) on actual or representative system components.

Definition: Anti-Tamper is the systems engineering activities intended to deter and/or delay exploitation of critical technologies in a system in order to impede countermeasure development, unintended technology transfer, or alteration of a system.

When is Testing for Ant-Tamper

The V&V plan, which is developed to support Milestone C, is reviewed and approved by the AT Executive Agent, or any DoD Component-appointed AT Agent, prior to the milestone decision. The Program Management Office (PMO) conducts the V&V of the implemented AT plan. The AT Executive Agent witnesses these activities and verifies that the AT plan is implemented into the system and works according to the AT plan. The PM and the AT Executive Agent may negotiate for parts of the system that have undergone anti-tamper measures to be tested at the AT Executive Agent’s laboratories for further analysis. The validation results are reported to the Milestone Decision Authority (MDA). [1]
