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将其加载到由存储器位置信息指示的区域中。根据存储器位置信息，多个部分程序被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，由于每次解密一些数据时，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： In a data processing apparatus that switches between a secure mode and a normal mode during execution, the secure mode allowing access to secure resources to be protected, the normal mode not allowing access to the secure resources, when the secure resources increase in the secure mode, the load on a protection mechanism for protecting the resources becomes large. Thus, there is a demand for data processing apparatuses that are able to reduce secure resources. The present invention relates to a data processing apparatus that stores therein a secure program including one or more processing procedures which use secure resources and a call instruction for calling a normal program to be executed in a normal mode. While executing the secure program, the data processing apparatus calls the normal program with the call instruction and operates according to the called normal program.

摘要： A semiconductor memory card comprising a control IC 302, a flash memory 303, and a ROM 304. The ROM 304 holds information such as a medium ID 341 unique to the semiconductor memory card. The flash memory 303 includes an authentication memory 332 and a non-authentication memory 331. The authentication memory 332 can be accessed only by external devices which have been affirmatively authenticated. The non-authentication memory 331 can be accessed by external devices whether the external devices have been affirmatively authenticated or not. The control IC 302 includes control units 325 and 326, an authentication unit 321 and the like. The control units 325 and 326 control accesses to the authentication memory 332 and the non-authentication memory 331, respectively. The authentication unit 321 executes a mutual authentication with an external device.

摘要： A predetermined number of erasable blocks positioned at a start of a volume area in a semiconductor memory card are provided so as to include volume management information. A user area following the volume management information includes a plurality of clusters. A data length NOM of an area from a master boot record & partition table sector to a partition boot sector is determined so that the plurality of clusters in the user area are not arranged so as to straddle erasable block boundaries. Since cluster boundaries and erasable block boundaries in the user area are aligned, there is no need to perform wasteful processing in which two erasable blocks are erased to rewrite one cluster.
