摘要： According to one embodiment, when sending a transmission target main data 21, an authentication-tag generator unit 13 generates an authentication tag 23 by using a main data 21 and a key data 22 stored in a key-data storage unit 12. A transmitter/receiver unit 14 adds the authentication tag 23 to the main data 32 sends as a transmission data. When receiving the received data 24a, the transmitter/receiver unit 14 divides the received data into a main data 21a and an authentication tag 23a. The authentication-tag generator unit 13 generates an authentication tag 23b for comparison. A received-data authentication unit 15 determines whether or not those the received authentication tag 23a and the authentication tag for comparison 23b match with each other. A different key data is used every time upon the authentication-tag generation and use time of each key data during a set period is restricted.
