Assignee: CUICA LLC
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 12:
13. A method comprising:
receiving a clock signal at a first frequency;
utilizing the clock signal to coordinate operations associated with a circuit, the operations comprising:
receiving an encryption sequence at a port from another system at the first frequency;
permitting data transfer from the port to a memory;
preventing data transfer from the memory to the port;
accessing the encryption sequence; and
storing the encryption sequence in the memory;

reading a portion of the encryption sequence from the memory at a second frequency that is less than the first frequency;
processing input using the portion of the encryption sequence;
generating an output based on the processing; and
implementing tamper detection using a blockchain, wherein the blockchain is constructed via combining a blockchain header with at least a portion of the encryption sequence, and wherein the tamper detection is implemented by performing periodic reads of the blockchain header that is altered from a default state due to tampering.
