Patent ID: 11861047
Assignee: CRYPTOGRAPHY RESEARCH, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 15:
16. A system comprising:
an integrated circuit comprising a set of propagation paths and a cryptographic circuit to perform a cryptographic operation; and
a power delivery network coupled to the integrated circuit, the power delivery network to deliver power to the integrated circuit, wherein the cryptographic circuit comprises:
a data store to store a mask share;
masked gate logic circuitry to output output signals on each of the set of propagation paths with equal probability during the cryptographic operation to mask secret data from being detected via power analysis of the power delivery network with at least a portion of the mask share; and
additional logic circuitry coupled to the masked gate logic circuitry, wherein the additional logic circuitry is to determine a final output based on a first output and a second output of the output signals, wherein the final output is independent of secret data that is masked in the masked data values.
