    摘要: In the key management software having a key database with a tree structure, a high-speed data encryption/decryption process is achieved by changing the tree structure without reducing the security strength when deleting or adding a key from/to the tree structure. The key management software having the key database with the tree structure, when deleting or adding a key from/to the tree structure, refers to the encryption strength comparison table and the process time comparison table to change the tree structure without reducing the security strength. This reduces the number of times an encrypted key is loaded onto the encryption/decryption processing device during the data encryption/decryption process, thus achieving a high-speed data encryption/decryption.

    摘要: The present invention provides an information processing device, an authentication system, etc. that save a server the trouble of updating a database, etc., even when a software module in a client device is updated, and that are capable of verifying whether software modules that have been started in the client device are valid. The terminal device A100 holds private keys 1 and 2, and performs authentication processing with the terminal device B101 using the private key 2. The private key 1 has been encrypted such that the private key 1 is decryptable only when secure boot is completed. The private key 2 has been encrypted such that the private key 2 is decryptable using the private key 1 only when the application module X that has been started is valid. When the authentication processing is successful, the terminal device B101 verifies that the terminal device A100 has completed secure boot and the application module X that has been started in the terminal device A100 is valid. Also, the terminal device B101 performs the authentication processing using the same private key 2, regardless of whether a program pertaining to the secure boot of the terminal device A100 is updated or not.

    摘要: A tamper detection device detects tampering with a program loaded to memory, at high speed and without compromising the safety. Prior to loading of a program, a dividing-size determining unit 12 determines a block size based on random number information, a dividing unit 13 divides the program by the block size into data blocks, and a first conversion unit 14 converts, by conducting a logical operation, the data blocks into intermediate authentication data no greater than the block size, and a second conversion unit 15 conducts a second conversion on the intermediate authentication data to generate authentication data. The authentication data and the block size are stored. After the program loading, a program resulting from the loading is divided by the block size, followed by the first and second conversions to generate comparative data. The comparative data is compared with the authentication data to detect tampering of the loaded program.
