Protecting Information Processing System Secrets From Debug Attacks |
| 摘要 |
Embodiments of an invention for protecting information processing system secrets from debug attacks are disclosed. In one embodiment, a processor includes storage, a debug unit, and a test access port. The debug unit is to receive a policy from a debug aggregator. The policy is based on a value of a first fuse and has a production mode corresponding to a production value of the first fuse and a debug mode corresponding to a debug value of the fuse. The test access port is to provide access to the storage using a debug command in the debug mode and to prevent access to the storage using the debug command in the production mode. |
