Information processing apparatus and computer readable medium for preventing unauthorized operation of a program
Abstract:
An information processing apparatus includes an information acceptance unit, a calculation unit and an encryption unit. The information acceptance unit accepts information relevant to a program. The calculation unit calculates one of a one-way function and a pseudo one-way function using one of the information relevant to the program accepted by the information acceptance unit and a part of the information. The encryption unit performs encryption processing for one of code of the program and the conversion result of the code and a part thereof using one of the calculation result of the calculation unit and a part of the result.
Abstract(Chinese):

信息处理装置包括信息接收单元，计算单元和加密单元。 信息接受单元接受与程序相关的信息。 计算单元使用与由信息接收单元接受的程序相关的信息和信息的一部分来计算单向函数和伪单向函数之一。 加密单元使用计算单元的计算结果和结果的一部分之一对程序的代码和代码的转换结果及其一部分执行加密处理。
