摘要： Provided are a utilization apparatus, a server apparatus, and a key utilization system which enable the utilization apparatus to control deletion of the old key without using a secure clock and allow encrypted communications irrespective of whether the accessed server has updated its key or not. In key utilization system 1, one or more server apparatuses 5-1 to 5-n each provide service to an apparatus having an apparatus key corresponding with a server key. Update apparatus 2 distributes an update server key to each server apparatus and a new apparatus key to key utilization apparatus 3. CRL distribution apparatus 4 distributes to key utilization apparatus 3 a CRL indicating one or more server apparatuses which have completed key-updating. Key utilization apparatus 3 holds both the old and new apparatus key, judges whether the server apparatuses monitored using the CRL have completed key-updating, and if affirmative, deletes the old apparatus key.

摘要： A terminal device that can, when delivering information to an other terminal device, control delivery of the information from a primary delivery destination to a secondary delivery destination is provided. The terminal device stores a primary delivery condition regarding whether delivery of the information to the primary delivery destination is prohibited or permitted, and trustability showing a degree of trust of a user in the primary delivery destination. The terminal device judges whether or not to deliver the information to the primary delivery destination, by using the primary delivery condition. When judging to deliver the information, the terminal device calculates a secondary delivery condition using the trustability and the primary delivery condition, the secondary delivery condition regarding whether delivery of the information from the primary delivery destination to the secondary delivery destination is prohibited or permitted. The terminal device sends the generated secondary delivery condition to the primary delivery destination.

摘要： An encryption apparatus prevents plaintext data from leaking even if accumulated data is analyzed, while preventing the size of encrypted data from increasing. The encryption apparatus encrypts a data piece that is smaller than a unit length and stores management information indicating a used area within an encryption area defined based on the unit length. The used area is an area already used for encryption. When encrypting a new data piece that is smaller than the unit length, the encryption apparatus generates encrypted data by adding the new data piece to an unused area within the encryption area with reference to the management information. The unused area is an area not yet used for encryption. The encryption apparatus updates the management information to include an area for the new data piece into the used area, after generating the encrypted data.
摘要翻译：即使分析了累积数据，加密装置也防止明文数据泄漏，同时防止加密数据的大小增加。加密装置对小于单位长度的数据进行加密，并将指示使用区域的管理信息存储在基于单位长度定义的加密区域内。使用区域是已经用于加密的区域。当加密小于单位长度的新的数据段时，加密装置通过参考管理信息将新的数据段添加到加密区域内的未使用区域来生成加密数据。未使用的区域是尚未用于加密的区域。在生成加密数据之后，加密装置更新管理信息以将新数据段的区域包括到使用区域中。
