摘要： A reception apparatus includes a first timer and sends to a distribution apparatus a first date-time clocked by the first timer. The distributing apparatus includes a second timer, and generates expiry information based on a difference obtained by subtracting, from the first date-time, a second date-time that is clocked by the second timer. The expiry information is used to adjust a usage expiry date-time of content. The reception apparatus judges whether playback of the content is permitted based on the first timer and the expiry information. With this arrangement, unauthorized use of the content beyond the expiry date-time is prevented.

摘要： A service user's personal information that has been verified and to which a digital signature has been attached by a personal information verification apparatus (signed-personal information) is stored in a highly secure form within a service user apparatus. For receiving services, the service user apparatus transmits the signed-personal information stored there into a service provider apparatus. The service provider apparatus verifies the signed-personal information based on the digital signature, and then provides services based on the personal information.

摘要： The subkey data generating unit 101 has two different subkey key generation processes. When encrypting a (T*n)th plaintex block (where T denotes a predetermined cycle and n is a positive integer), sixteen sets of subkey data are generated. In all other cases, two sets of subkey data are generated. The encrypting unit 100 encrypts the plaintex using the generated sixteen or two sets of subkey data.
摘要翻译： 子密钥数据生成单元101具有两个不同的子密钥密钥生成处理。 当加密（T * n）第明文块（其中T表示预定周期，n是正整数）时，生成十六组子密钥数据。 在所有其他情况下，都会生成两组子密钥数据。 加密单元100使用生成的十六组或两组子密钥数据来加密明文。

摘要： An encryption transmission apparatus and an encryption reception apparatus avoid attack that takes advantage of a re-transmission request. A server apparatus encrypts a content key five times, thereby generating five encrypted content keys, calculates a hash value of the content key, and transmits the five encrypted content keys and the hash value. An image playback apparatus receives the five encrypted content keys and the hash value, decrypts the five encrypted content keys thereby generating five content keys, calculates hash values, each corresponding to the generated content keys, and compares the calculated hash values with the received hash value, respectively. If at least one of the five calculated hash values matches the received hash value, the corresponding content key is considered correct. Conversely, if none of the five calculated hash values matches the received hash value, it is considered a decryption error.

摘要： At the time of manufacturing a DVD to be provided to a rental agent, a provider device writes an agent-rental expiry along with contents onto the DVD. At the time of renting the DVD to a user, a rental agent device writes a user-expiry onto the DVD. A DVD player acquires a current time from a time source device, and compares the current time with each of a prior time, the agent-rental expiry, and the user-rental expiry. The DVD player plays back the content only when playback conditions are met.
