    • Reduces message length of encrypted message to be transmitted selectively to plurality of decrypting devices. An encrypting device includes a generating unit for generating node associating information configured to associate respective terminal nodes in a tree structure with each decrypting device in relation to a group of decrypting devices enabled for decryption, an extracting unit for extracting a decryption enabled node containing decrypting devices in descendant terminal nodes and not containing a decrypting device with decryption disabled in any of the descendant terminal nodes, and a unit for encrypting the message by use of a node encryption key for the decryption enabled node. Decrypting devices include specifying unit for specifying terminal node associated with decrypting device based on node associating information, and a decrypting unit for decrypting encrypted message using a node decryption key for any decryption enabled nodes ranging from terminal node to root node thereof.

    • A method for eliminating ambiguity and incorrectness of the specification determined in a requirement defining phase in developing an information system, and systematically verifying whether an automatically executed test scenario agrees with the original requirements in a functional testing phase, includes extracting an input variable, an output variable, and the respective types of the variables from a specification file in screens; extracting screen-transition information from a composite functional specification containing specifications in screens; and executing the following processes from the top for each screen that appears in screen transition. For the input variable, the apparatus generates a test script indicative of an action (clicking or a character set) corresponding to an object associated with the input variable. For the output variable, the apparatus generates a test script for comparing text information displayed on a screen with an expected value determined from the output variable.
    • 一种用于消除在开发信息系统中定义阶段的要求中确定的规范的不明确性和不正确性的方法,并且系统地验证自动执行的测试场景是否与功能测试阶段中的原始需求一致,包括提取输入变量,输出 变量,以及屏幕中规范文件中各变量的类型; 从包含屏幕中的规格的复合功能规范提取屏幕转换信息; 并从屏幕转换中出现的每个屏幕的顶部执行以下处理。 对于输入变量,设备生成指示对应于与输入变量相关联的对象的动作(点击或字符集)的测试脚本。 对于输出变量,设备生成用于将屏幕上显示的文本信息与从输出变量确定的期望值进行比较的测试脚本。

    • A ballistic memory cell structure employing ballistic transistor technology for switching between a read state and a store state is disclosed. The memory cell structure includes substrate structures forming a side wall and a main chamber for defining a linear ballistic channel between the two. The main chamber is formed to include a deflection channel with deflective surfaces to deflect an electron emitted from an electron source into the memory cell structure. Deflection controllers are coupled to the substrate structures for generating biasing fields that adjust the trajectory of electrons flowing through the linear ballistic channel and the deflection channel. Logic output terminals are positioned beyond channel exits for registering exiting electrons and determining a read or store state.

    • A database management system for determining consistency in a hierarchical database sequentially reads pointers of a plurality of segment data, generates an address hash value, which is a hash value of retention addresses of the segment data having been read, generates a pointer hash value, which is a hash value of the pointers included in the segment data having been read, corrects the address hash value, when the contents of the address already read is updated, based a retention address of segment data added or deleted by the update, corrects the pointer hash value based on each pointer changed by the update, and determines that the hierarchical database is consistent if the corrected address hash value coincides with the corrected pointer hash value.
