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： An information processing apparatus includes: a CPU (1201) that has, as an operating mode, a privileged mode and an unprivileged mode; a trusted memory (1270) that stores protected data, the protected data being accessed when the CPU (1201) is in the unprivileged mode; and a trusted memory control unit (1203) that controls access to the trusted memory (1270). When the CPU (1201) accesses the trusted memory (1270), the trusted memory control unit (1203) determines the operating mode of the CPU (1201) and, in the case where the operating mode of the CPU (1201) is the unprivileged mode, denies the access to the trusted memory (1270) by the CPU (1201).

摘要： Provided is a key migration device which can securely and reliably control the migration of keys. A migration authority (101) fetches a generation level which is the security level of a first electronic terminal (3011) and an output destination level which is the security level of a third electronic terminal (3013), decides whether the relationship between the generation level and the output destination level satisfies a predetermined condition when a request for fetching a collection of keys is received from the third electronic terminal (3013), outputs the key generated by the first electronic terminal (3011) among the collection of keys to the third electronic terminal (3013) if the predetermined condition is fulfilled, and restricts output to the third electronic terminal (3013) of the key generated by the first electronic terminal (3011) among the collection of keys if the predetermined condition is not fulfilled.

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： To play back a content while managing the right of use of the content, such as a total time of playback of the content, an electronic device stores right information in a right temporary storage unit 59 and judges whether or not use of the content is permitted, in a process of decoding a frame. Also, the electronic device updates the right information stored in the right temporary storage unit 59. When the frame to be played back is the one at a predetermined position in order, the electronic device stores the right information stored in the right temporary storage unit 59 into a storage area 20.

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.
