Abstract
In a cryptographic module distribution system, a cryptographic management server apparatus encrypts a cryptographic module using a key shared by a cryptographic apparatus, and transmits the encrypted cryptographic module to a client apparatus. The client apparatus transmits the encrypted cryptographic module to a cryptographic apparatus. The cryptographic apparatus decrypts the encrypted cryptographic module using the key shared by the cryptographic management server apparatus, and transmits the decrypted cryptographic module to the client apparatus. The client apparatus stores the received cryptographic module.
