    摘要: A message receiving apparatus for receiving messages from a message transmitting apparatus generates first data for producing a display which urges a user of the message transmitting apparatus to input a message, and generates second data within the first data for specifying a conversion type for secret communication of the message. The message receiving apparatus sends the first data including the second data to the message transmitting apparatus and subsequently receives the message from the message transmitting apparatus. The message transmitting apparatus for transmitting messages to the message receiving apparatus receives the first data for producing the display and the accompanying second data for specifying the conversion type and produces the display according to the first data. On receiving the message inputted by the user in response to the display, the message transmitting apparatus converts the input message according to the second data and transmits the converted message to the message receiving apparatus.

    摘要: A program loader-for loading a program onto a memory in accordance with load-destination information, the program loader including: an obtaining unit operable to obtain the load-destination information from a recording medium in which the program is recorded; a verifying unit operable to verify whether or not the load-destination information has been tampered with; and a loading unit operable to load the program. The load-destination information indicates a memory area which is part of an address space in the memory, wherein an execution image of the program is to be stored in the address space, and if the verifying unit verifies that the load-destination information has not been tampered with, the loading unit generates, as the loading of the program, the execution image in the memory area indicated by the load-destination information, such that the execution image is executed.

    摘要: In a cryptography system, plaintext storage unit 101 stores a plaintext. Encryption unit 102 encrypts the plaintext to generate a ciphertext. First verification data generating unit 104 generates first verification data, and second verification data generating unit 106 generates second verification data. Decryption unit 114 decrypts the ciphertext to generate a decrypted plaintext. First verification unit 116 performs verification using the decrypted plaintext and the first verification data. Second verification unit 117 performs verification using the first verification data, the ciphertext, and the second verification data. Display unit 112 displays the results of the verifications.
