摘要： A distribution server (103) distributes a content via a network, and a KIOSK terminal (105) receives the content via the network and records the content in an SD memory card (100). A customer device (111) receives a content via the SD memory card (100), checks out the content and records a copy on a recording medium. SD-Audio players (122 to 124) receive a copy of the content and play back the copy. Here, the KIOSK terminal (105) records a Usage Rule that certifies the right to control recording of content on the SD memory card (100). Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.

摘要： An encrypted-data decrypting apparatus that provides enhanced security protection for programs and data while they are in the processes of decryption to execution after having been encrypted. When a decrypted partial program needs to be loaded into the shared memory (M), the controlling unit (11) loads it into an area indicated by the memory location information. According to the memory location information, a plurality of partial programs are sequentially loaded into an area so that one partial program gets overwritten by another; therefore, none of the partial programs exists in the memory for a long time, and thus there is less possibility of having the partial programs referred to illegitimately. In addition, since every time some data is decrypted, the decryption support program authenticating unit (13) confirms authenticity of the decryption support program (P), it is possible to prevent having illegitimate references in which the decryption support program is abused.
摘要翻译：一种加密数据解密装置，当它们在被加密之后处于解密到执行的过程中时，为程序和数据提供增强的安全保护。当解密的部分程序需要加载到共享存储器（M）中时，控制单元（11）将其加载到由存储位置信息指示的区域中。根据存储器位置信息，将多个部分程序顺序地加载到一个区域中，使得一个部分程序被另一部分程序重写; 因此，部分程序中的任何一个都不存在于存储器中很长一段时间，因此部分程序被非法地引用的可能性较小。此外，由于每当解密数据被解密时，解密支持程序认证单元13确认解密支持程序（P）的真实性，所以可以防止具有解密支持程序被滥用的非法参照。

摘要： A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.
