Abstract
A one-time-settable tamper resistant software repository may be used in any computing system to store system information such as security violations and policies for responding to them. A one-time-settable tamper resistant software repository may be cryptographically signed, encrypted with a per device key and accessible by only the most privileged software executed by a computing device, e.g., hypervisor or operating system kernel. A one-time-settable tamper resistant software repository may be mirrored in RAM for performance. Recordable event fields in a software repository may be one-time-settable without the ability to reset them in a field operation mode whereas they may be resettable in a different mode such as a manufacturing mode. Memory allocated to a one-time-settable tamper resistant software repository may be reset, reclaimed, reassigned, scaled and otherwise flexibly adapted to changing conditions and priorities in the lifespan of a computing device, which may be particularly useful for service-backed consumer devices.
