摘要:
A cryptographic hardware module has an arithmetic unit, a memory storing at least one first key, a logic and a cryptographic device. The hardware module loads at least one second encrypted key into the hardware module and decrypts the at least one second encrypted key via the cryptographic device using the at least one first key.
