  • Patent number: 10193691
    Abstract: According to an embodiment, an information processing device includes a conversion unit, an encryption unit, and a transmission unit. The conversion unit converts a first encryption key to be used for generation of a master key to be shared with a server device by using a second conversion rule to generate a third encryption key to be a new master key. The second conversion rule is different from a first conversion rule used for generation of a second encryption key that is the master key currently used for encrypted communication with the server device. The encryption unit generates a ciphertext so that the server device derives the third encryption key on a basis of the second encryption key and the third encryption key. The transmission unit transmits the ciphertext to the server device.
