Abstract
A cryptographic processor for redundantly-processing cryptographic operations is disclosed. The cryptographic processor includes a number of input ports, a first and second cryptographic engines, comparison logic and a plurality of output ports. The number of input ports is configured to accept both plaintext and ciphertext. Each of the number of input ports is coupled to both the first and second cryptographic engines. The comparison logic is configured to determine if the first and second cryptographic engines produce a result that is different. The number of output ports is configured to produce both plaintext and ciphertext.
