摘要： A control apparatus for a master-slave robot includes a force correction section detecting unit that detects a section at which force information from at least one of force information and speed information is corrected, and a force correcting unit that corrects the force information at a section detected as a force correction section by the force correction section detecting unit. A small external force applied to a slave manipulator is magnified and transmitted to a master manipulator, or an excessive manipulation force applied to the master manipulator is reduced and transmitted to the slave manipulator.

摘要： Provided is a migration system considering security authentication levels and data protection strength levels of the both security devices between which data is migrated. A first terminal includes a mechanism for protecting data by a private key in the public key method held by TPM, and a second terminal includes a key in the private key method encrypted by the private key in the public key method held by TPM and a mechanism for protecting the data by the key. A Migration Authority holds a security policy table describing a security policy and judges whether data movement from the first terminal to the second terminal is enabled according to the security policy table.

摘要： To provide a program conversion device capable of executing a program that includes a secret operation using secret information without exposure of the secret information in a memory. In an execution program generation device, with respect to an original program that includes the secret operation, a combining function generation unit generates combining function processing for applying a bitwise self-dual function to an input value, a split secret information generation unit generates pieces of split secret information by performing an inverse operation of the self-dual function, a program conversion unit generates pieces of split secret operation processing each for performing the operation between each bit value of the operand information and a corresponding bit value of a different piece of the split secret information, and replaces the secret operation processing with the pieces of the split secret operation processing and the combining function processing.

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.

摘要： An encrypted-data decrypting apparatus that provides enhanced security protection for programs and data while they are in the processes of decryption to execution after having been encrypted. When a decrypted partial program needs to be loaded into the shared memory M, the controlling unit 11 loads it into an area indicated by the memory location information. According to the memory location information, a plurality of partial programs are sequentially loaded into an area so that one partial program gets overwritten by another; therefore, none of the partial programs exists in the memory for a long time, and thus there is less possibility of having the partial programs referred to illegitimately. In addition, since every time some data is decrypted, the decryption support program authenticating unit 13 confirms authenticity of the decryption support program P, it is possible to prevent having illegitimate references in which the decryption support program is abused.
