Abstract
A request associated with a revocation of a key may be received. A hash value corresponding to the key that is stored in a memory may be identified. Furthermore, the hash value that is stored in the memory may be corrupted in response to the request associated with the revocation of the key.
Claims20
A method comprising:
- receiving a request associated with a revocation of a key;
- identifying a hash value corresponding to the key, the hash value being stored in a memory;
- and
- corrupting, by a processing device, the hash value that is stored in the memory in response to the request associated with the revocation of the key.

A system comprising:
- a one-time programmable (OTP) memory to store a plurality of hash values, wherein each of the plurality of hash values corresponds to a different key;
- and
- a hash value controller, comprising a processing device and coupled with the OTP memory, to:
- receive a request associated with a disabling of a key;
- identify a hash value of the plurality of hash values stored in the OTP memory that corresponds to the key;
- and
- corrupt the hash value that corresponds to the key in response to the request associated with the disabling of the key.
4 more elements
A non-transitory computer readable medium including data that, when accessed by a processing device, cause the processing device to perform operations comprising:
- receiving a request associated with a revoking of a key;
- identifying a hash value corresponding to the key, the hash value being stored in a memory, wherein the hash value comprises a first plurality of bits at a first value and a second plurality of bits at a second value;
- and
- corrupting the hash value that is stored in the memory based on the request associated with the revoking of the key by changing a at least one bit of the second plurality of bits from the second value to the first value.
