Abstract
A chassis platform, such as processor or a system-on-chip (SoC), includes logic to implement a debug chassis security system including a policy generator to control access from a test access port. The policy generator may distribute a debug policy to at least one logic block that locally enforces the debug policy. The debug policy may include a delayed authentication policy in which debug assets are distributed and the chassis platform is initially locked to prevent debug access via the test access port. An authenticated debug user may unlock the chassis platform at a later time to enable debugging operations. The debug policy may also include a live execution policy and an immediate debug policy.
