For the packet encryption/decryption, each packet processing device determines whether or not to encrypt/decrypt the packet according to: an information on the computers which are directly managed by this packet processing device; or the encryption information and the signature information provided in the packet; or the encryption information, the signature information, and the encryption/decryption level information provided in the packer.
