Abstract
A computer platform is disclosed. The computer platform comprises a non-volatile memory to store fuse override data; and a system on chip (SOC), coupled to the non-volatile memory, including a fuse memory to store fuse data and security micro-controller to receive the fuse override data and perform a fuse override to overwrite the fuse data stored in the fuse memory with the fuse override data.
Claims20
A computing device comprising:
- a fuse memory to store fuse data;
- and
- a cryptographic processor to receive fuse override data and perform a fuse override to overwrite the fuse data stored in the fuse memory with the fuse override data to validate a boot startup of the computing device.
A method comprising:
- retrieving fuse override data from a non-volatile memory;
- and
- performing a fuse override at an integrated circuit (IC), including overwriting fuse data stored in a fuse memory with the fuse override data to validate a boot startup of a computing device, wherein the fuse data comprises a fuse update data structure including a header section and a body section.
At least one computer readable medium having instructions stored thereon, which when executed by one or more processors, cause the processors to:
- retrieve fuse override data from a non-volatile memory;
- and
- perform a fuse override at an integrated circuit (IC), including overwriting fuse data stored in a fuse memory with the fuse override data to validate a boot startup of a computing device, wherein the fuse data comprises a fuse update data structure including a header section and a body section.
