INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM, AND ENCRYPTION INFORMATION MANAGEMENT METHOD

摘要

According to one embodiment, an encryption information management method for an information processing apparatus that includes a user virtual machine and a management virtual machine running at the same time is described. The method comprises the following operations by the management virtual machine: (i) receiving information for decrypting data, the data being encrypted using a cryptographic key from the user virtual machine; (ii) dividing the information for decrypting data into information blocks; (iii) constructing information items based on the information blocks, each of the information blocks being included in the information items in a multiplexed manner, each of the information items comprises two or more information blocks of the information blocks; (iv) transmitting the information items to management virtual machines in other information processing apparatuses that are communicatively coupled with the management virtual machine for storage; and (v) deleting the decrypting information in the management virtual machine.
