    摘要: A memory management unit manages a memory that stores a code, and sets that the memory that stores the code to be executed is valid to make a processor execute the code stores a verification key used to verify a validity of the code in a verification-key storing unit. When the code is stored in the memory and ready to be executed by the processor, the memory management unit verifies the validity of the code using the verification key stored in the verification-key storing unit and verification information assigned to the code. The memory management unit controls to set that the memory is valid when the validity is verified by the verifying unit, and not to set that the memory is valid when the validity is not verified by the verifying unit.

    摘要: An encryption communication system including: a communication center having at least a key information generating unit for generating key generating information used for encryption communication; and a plurality of user computers, each interconnected by a plurality of paths through the communication center, and each having at least an encryption key generating unit and an encryption processing unit. The communication center generates the key generating information Z based on predetermined modulo arithmetic formula. The user computer sends a password PW to the communication center, receives the key generating information therefrom, and generates an encryption key K used between the user computer and another party's computer based on predetermined modulo arithmetic formula. Further, the communication center provides a plurality of modulus numbers to share prime numbers assigned to at least two paths between the user computer and the other party's computer, and between the user computer and another party's computer, so that is possible to reduce the number of prime numbers.

    摘要: An advertisement management device generates and manages advertisement information and an advertisement identifier, a tag management unit generates a tag identifier and tag information unique to the tag identifier, and manages the tag identifier, the tag information, and the advertisement identifier generated by the advertisement management device in associated manner. The tag management unit sends the tag identifier and the advertisement identifier to the radio tag. A reader reads the tag identifier and the advertisement identifier from the radio tag, sends the tag identifier to the tag management unit, and sends the advertisement identifier to the advertisement management unit. The tag management unit sends tag information corresponding to the tag identifier received from the reading unit to a display unit, and the advertisement management unit sends advertisement information corresponding to the advertisement identifier received from the reading unit to the display unit.
