    Abstract: For encryption of an encryption-targeted data segment, the information processing device executes steps of: accepting input of an encryption method of a next data segment as well as a decryption key of the next data segment encrypted by the encryption method; adding, to the encryption-targeted data segment, next-data information including the encryption method and the decryption key; and encrypting the encryption-targeted data segment with the next-data information added thereto, and afterwards for encryption of the next data segment, the information processing device encrypts the next data segment on a basis of the encryption method and the decryption key included in the next-data information of the encryption-targeted data segment.
