    • 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.
    • 监视系统具有经由网络加密连续数据并分发加密的连续数据的分发装置,对通过网络分发的加密数据进行解密以再现连续数据的再现装置,以及具有密钥管理数据库的密钥管理装置 。 分发装置从密钥管理装置获得与分发装置相关的密钥号码和与密钥号码相关的密钥信息,并使用获得的密钥信息对数据进行加密,并使用获得的密钥号码分发加密数据。 再现装置将附加到加密数据的密钥号码发送给密钥管理装置,获得与发送的密钥号码相关的密钥信息,并使用获得的密钥信息对加密数据进行解密。
