ABSTRACT:
A system including a secure LSI1establishes a communication path to/from a server3(UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server3(UD6and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.
