Abstract
A communication apparatus communicates with another communication apparatus by using a first key. The communication apparatus includes a processing unit that conducts a handshake process for a key exchange with the another communication apparatus and a key encryption unit that conducts an encryption process by using a second key. The processing unit conducts a first handshake process with the another communication apparatus without exchanging information on the first key while serving as a reception side of key information. Then, the processing unit conducts a second handshake process with the another communication apparatus to transmit the information on the first key encrypted by the key encryption unit by using the second key to the another communication apparatus.
