    • To facilitate protected distribution of digital data files, the files are segmented, and each segment (e.g. disk sector) is encrypted separately. Some segments can be left unencrypted, speeding access since less decryption is required. Different segments can utilize different encryption techniques, increasing protection against unauthorized decryption. A table stored in association with the encrypted data provides authorized users with data identifying the encrypted segments, and the form of encryption used. Decryption is accomplished with a layered set of operating system software that operates in conjunction with said table. Specialized APIs aren't used; applications programs are provided with unencrypted data using conventional APIs. Internal interfaces, invisible to the APIS, intercept normal processing calls (e.g READs) and direct them to internal decryption software that returns decrypted data back to the APIs.
    • 为了方便数字数据文件的保护分发,文件被分割,并且每个段(例如磁盘扇区)被单独加密。 一些段可以保持不加密,加速访问,因为需要较少的解密。 不同的段可以利用不同的加密技术,增加对未经授权的解密的保护。 与加密数据相关联地存储的表格为授权用户提供标识加密段的数据以及所使用的加密形式。 解密是通过与所述表一起操作的分层操作系统软件来实现的。 不使用专用API; 应用程序使用常规API提供未加密的数据。 APIS不可见的内部接口拦截正常的处理调用(例如READ),并将它们引导到将解密后的数据返回给API的内部解密软件。

    • In order to generate a source program or an object code which can be executed in parallel efficiency by detecting an independent operation of a large grain size from a program which can not be analyzed by the compiler, a parallelization supporting tool inputs a result of an output of the interprocedural analyzer 120 and the source program. A program of intermediate language is produced by the parse and the program of information of common and dummy argument variables is reflected into the program of intermediate language by the interprocedural variable information read processing. After a control flow analysis and a dataflow analysis have been carried out, dependency unknown variables are extracted and parallelizability conditions are produced. Based on the result of the produced conditions, questions and answers are made with the user or a condition statement is inserted into the source program to execute the program and a decision of parallelizability is made. A source program or a parallelized object program which has been corrected in accordance with a user's request is also produced.
