A cryptographic management apparatus includes a storage unit which stores cryptographic key information containing a cryptographic key and cryptographic process condition information containing the cryptographic key information, a cryptographic process information input unit which receives an input of the object information and cryptographic key search request information, a cryptographic key information acquisition unit which acquires the cryptographic key information from the storage unit based on the search request information, a cryptographic module evaluation description information acquisition unit which acquires evaluation description information of the cryptographic module corresponding to the cryptographic key information, a cryptographic process ID creation unit which attaches an identifier of the cryptographic process condition information to the object information based on the cryptographic key information and the cryptographic module corresponding to the evaluation description information, and an output which outputs the identifier and the result of the cryptographic process executed on the object information.

Cryptographic management apparatus, decryption management apparatus and program

A cryptographic client device acquires a cryptographic key from a storage device son the basis of the accepted demand information, acquires a cryptographic evaluation description file from the storage device, acquires a cryptographic module corresponding to this cryptographic evaluation description file, executes a cryptographic process on the subject data to be performed the cryptographic process, and issues the encrypted subject data.

Software module management device and program

A cryptographic module management apparatus searches for cryptographic module meta-information based on the category information of a requested cryptographic module and, if associated cryptographic module category information is contained in this cryptographic module meta-information, searches for the cryptographic module meta-information of an associated cryptographic module, to generate composite type cryptographic module evaluation information based on this cryptographic module meta-information, select a cryptographic module based on this composite type cryptographic module evaluation information, and read this cryptographic module from a cryptographic module storage portion and output such composite type cryptographic module evaluation information.

Cryptographic module management apparatus, method, and program

In a cryptographic module distribution system, a cryptographic management server apparatus encrypts a cryptographic module using a key shared by a cryptographic apparatus, and transmits the encrypted cryptographic module to a client apparatus. The client apparatus transmits the encrypted cryptographic module to a cryptographic apparatus. The cryptographic apparatus decrypts the encrypted cryptographic module using the key shared by the cryptographic management server apparatus, and transmits the decrypted cryptographic module to the client apparatus. The client apparatus stores the received cryptographic module.

Cryptographic module distribution system, apparatus, and program

A cryptographic module selecting device includes a cryptographic module evaluation information storage device configured to store identification information of a cryptographic module and cryptographic module evaluation information describing a function and/or performance of the cryptographic module in relation to each other, a condition information acquiring device configured to acquire condition information for specifying the condition of the cryptographic module to be selected, an extracting device configured to extract cryptographic module evaluation information conforming to the acquired condition information, from the stored cryptographic module evaluation information of the cryptographic module, and an output device configured to read out the identification information of the cryptographic module corresponding to the cryptographic module evaluation information selected by the extracting device from the cryptographic module evaluation information storage device and output the read identification information.
