Technical details and manufacturing context for Key Register Bank

Definition
The Key Register Bank is a critical hardware component within the Cryptographic Engine Core responsible for the secure storage, retrieval, and management of cryptographic keys. It acts as a protected repository where symmetric keys, asymmetric private keys, and initialization vectors are held during cryptographic processing. Its design ensures keys are isolated from general-purpose memory and accessible only to authorized cryptographic circuits, preventing unauthorized access or leakage.
Working Principle
The Key Register Bank operates by receiving keys from a secure key loader or key derivation function. It stores these keys in volatile or non-volatile registers with hardware-based access controls. When the cryptographic engine requires a key for an operation (e.g., AES encryption), it sends a request to the Key Register Bank. The bank authenticates the request, retrieves the specified key from its protected storage, and transfers it directly to the relevant cryptographic processing unit (e.g., cipher block), ensuring the key is never exposed on external buses or in unprotected memory.

Silicon (for integrated circuits), Metal interconnects (e.g., copper)
