Abstract:
A project managing unit 11 authenticates users of virtual machines 24-1 to 24-N and specifies a project to which the users belong. A key managing unit 12 distributes an encryption key, which is assigned in advance to the project specified by the project managing unit 11, to encryption processing units 232-1 to 232-N of virtualizing units 23-1 to 23-N. Input/output monitoring units 231-1 to 231-N of the virtualizing units 23-1 to 23-N receive input/output data generated between the virtual machines 24-1 to 24-N and devices 22-1 to 22-N, and deliver the data to the encryption processing units 232-1 to 232-N. The encryption processing units 232-1 to 232-N encrypt output (write) data and decrypt input (read) data by using the distributed encryption key.
