Abstract
A processing system includes a first processing unit; a second processing unit; and a cryptographic coprocessor communicatively coupled to the first processing unit and the second processing unit. The cryptographic coprocessor includes a key storage memory for storing a cryptographic key; a first interface configured to receive source data to be processed directly from the first processing unit; a hardware cryptographic engine configured to process the source data as a function of the cryptographic key stored in the key storage memory; a second interface configured to receive a first cryptographic key directly from the second processing unit; and a hardware key management circuit configured to store the first cryptographic key in the key storage memory.
