System, apparatus and method for secure monotonic counter operations in a processor

At least one non-transitory computer readable storage medium comprising instructions that when executed enable a system to:

• responsive to receipt of a request from a requester to update a monotonic counter of a processor, determine whether the processor is in a first security mode;
• when it is determined that the processor is in the first security mode, access, via logic of the processor, the monotonic counter using an identifier associated with the request, the logic to index into a table of monotonic counters with the identifier to access the monotonic counter;
• increment, via the logic, a value of the monotonic counter;
• output, via the logic, the value of the monotonic counter to the requester;
• and
• update the monotonic counter when a user enters or exits a geo fence.

A method comprising:

• responsive to receipt of a request from a requester to update a monotonic counter of a processor, determining whether the processor is in a first security mode;
• when it is determined that the processor is in the first security mode, accessing, via logic of the processor, the monotonic counter using an identifier associated with the request, the logic to index into a table of monotonic counters with the identifier to access the monotonic counter;
• incrementing, via the logic, a value of the monotonic counter;
• outputting, via the logic, the value of the monotonic counter to the requester;
• accessing secure content if the value of the monotonic counter has not met a policy threshold, and otherwise preventing the access to the secure content, the monotonic counter associated with the secure content;
• and
• encrypting the monotonic counter and sending the encrypted monotonic counter to a second computing system, responsive to a request to provide the secure content to the second computing system.
