Abstract
A request to generate a first key may be received. A device generated key that is stored in a memory may be received in response to the request. Furthermore, a first entity identification (ID) that is stored in the memory may be received. The first key may be generated based on the first entity ID and the device generated key that are stored in the memory.
Claims20
A method comprising:
- receiving a request to generate a first key;
- receiving device generated key being stored in a memory;
- receiving a first entity identification (ID) being stored in the memory;
- and
- generating the first key based on the first entity ID and the device generated key being stored in the memory.
2 more elements
A system comprising:
- a memory to store a device generated key and a first entity identification (ID);
- and
- a key deriver coupled with the memory and to:
- receive a request to generate a first derived key;
- receive the device generated key and the first entity ID from the memory in response to the request to generate the first derived key;
- and
- generate the first derived key based on the first entity ID and the device generated key from the memory.
4 more elements
An apparatus comprising:
- a one-time programmable (OTP) memory to store a device generated key and a first entity identification (ID);
- and
- a one-way function component coupled to the OTP memory and to:
- receive a request to generate a first derived base key;
- receive the device generated key being stored in the OTP memory;
- receive the first entity ID being stored in the memory;
- and
- generate the first derived base key based on the first entity ID and the device generated key being stored in the OTP memory.
