摘要
Provided with a calculation device capable of calculating an encrypted data efficiently. A calculation device of the present invention is a device for performing a calculation for an encryption data in a virtual execution environment protected from a standard execution environment, the calculation device has a virtual execution environment construction unit for constructing the virtual execution environment, and the virtual execution environment includes: an encryption data acquisition unit for acquiring the encryption data; a source code acquisition unit for acquiring a source code for the calculation; a key acquisition unit for acquiring the system key; a decryption unit for decrypting the encryption data by the acquired system key; a source code execution unit for executing the source code; an encryption unit for encrypting a calculation result to which the source code is executed by the system key; and a calculation result providing unit for providing the encrypted calculation result to the standard execution environment.
