These are data item specification sections for specifying data items to be encrypted or decrypted, respectively. As shown in FIG. 7, the data sent from the external device 706 is decrypted by the decoding unit 703 and sent to the data processing unit 702 for data processing. When sending data from the radiation treatment planning apparatus 701 to the external apparatus 706, the data is encrypted by the encryption unit 704 and sent to the external apparatus 706. The data item to be encrypted or the data item to be decrypted can be arbitrarily set by the data item specification unit 705. External device 7
Data can be transmitted and received between the radiological treatment planning apparatus 06 and the radiation treatment planning apparatus 701 via the recording medium 102 or the network 180. As described above, since data transmitted and received between the radiation treatment planning apparatus 701 and the external apparatus 706 is encrypted, even if a third party obtains the data, the data cannot be decrypted. Can protect confidentiality.

As described above, according to the eighth embodiment, since the data transmitted and received between the radiation treatment planning device 701 and the external device 706 is encrypted, a third party should obtain the data.
