    • An application program that was encrypted by using a predetermined secret key is input to an input section that is a part of a program execution system, and encrypted sentences as the encrypted application program are supplied to a decoding section as they are. The decoding section is supplied not only with the encrypted sentences from the input section but also with a publicized key corresponding to a secret key that was used in generating the encrypted sentences. The decoding section decodes the encrypted sentences by using the publicized key and supplies Java byte codes as a decoding result to a Java virtual machine. The Java virtual machine interprets and executes the Java byte codes that are supplied from the decoding section.
    • 通过使用预定的秘密密钥加密的应用程序被输入到作为程序执行系统的一部分的输入部分,作为加密的应用程序的加密的句子被原样提供给解码部分。 解码部分不仅从输入部分提供加密的句子,还提供与用于生成加密句子的秘密密钥对应的公开密钥。 解码部分通过使用公开的密钥解码加密的句子,并将Java字节码作为解码结果提供给Java虚拟机。 Java虚拟机解释并执行从解码部分提供的Java字节码。

    • When a first program executed on a first processor of a plurality of processors of a multiprocessing system intends to lock a given shared resource of a main memory in order to use same, if the desired resource is in use by a second program executed on a second processor, the first processor awaits an unlock signal which indicates that one of the shared resources is released for use. The first processor responds to the unlock signal and checks whether or not the desired resource is available. If not available, the first program again awaits the reception of the unlock signal, while if available, the first program accesses the desired resource to use same.
    • 当在多处理系统的多个处理器的第一处理器上执行的第一程序意图锁定主存储器的给定共享资源以便使用相同时,如果期望的资源在第二个程序上执行的第二个程序正在使用中 处理器,第一处理器等待解锁信号,其指示其中一个共享资源被释放以供使用。 第一个处理器响应解锁信号并检查所需资源是否可用。 如果不可用,则第一程序再次等待接收解锁信号,如果可用,则第一程序访问期望的资源以使用它。
