    摘要: An encryption key device can be freely attached to and detached from an information processor encrypting or decrypting data and includes a memory, a pseudorandom number generator, and a controller. The memory stores an application program to operate the encryption key device and a group ID specifying permission for use of the encryption key device. The pseudorandom number generator generates a pseudorandom number according to an encryption function using the group ID stored in the memory as an initial value of the encryption function. The controller causes the pseudorandom number generator to generate the pseudorandom number according to data size received from the information processor operating according to the application program and sends the generated pseudorandom number and the group ID read from the memory to the information processor.
