摘要：
An information processing device includes: a receiving unit that receives a first random number from another information processing device; a generating unit that generates a second random number; a time-variant-key generating unit that generates a time variant key for encryption according to the second random number; an encrypting unit that encrypts the first random number with the time variant key; and a transmitting unit that transmits the first random number encrypted by the time variant key and the second random number to the other information processing device.
