    摘要： A monitoring system has a distribution apparatus which encrypts continuous data and distributes the encrypted continuous data via a network, a reproduction apparatus which decrypts the encrypted data distributed via the network to reproduce the continuous data, and a key management apparatus which has a key management database. The distribution apparatus obtains a key number correlated with the distribution apparatus and key information correlated with the key number from the key management apparatus, encrypts data with using the obtained key information, and distributes the encrypted data with the obtained key number. The reproduction apparatus transmits the key number appended to the encrypted data to the key management apparatus, obtains key information correlated with the transmitted key number, and decrypts the encrypted data with using the obtained key information.

    摘要： An authentication method is provided in which authentication is performed between terminals respectively belonging to a first realm and a second realm that is different from the first realm, with using a Kerberos authentication method. In order to obtain authentication with a terminal belonging to the second realm, a terminal belonging to the first realm requests a ticket granting ticket for accessing a key distribution center in the second realm, from a key distribution center in the first realm. The key distribution center in the first realm transmits an encrypted IP address of the key distribution center in the second realm together with the requested ticket granting ticket, to the terminal belonging to the first realm.
