Abstract
Provided is a transmission apparatus capable of avoiding unnecessary decryption and preventing a denial-of-service attack. The transmission apparatus that establishes a secure communications channel (SA) between the transmission apparatus and a reception apparatus includes a creation section that creates a packet, an encryption section that, based on a ratio of a redundant packet to the packets created by the packet creation section and on an instruction from the reception apparatus, determines an encryption coverage in the created packet and encrypts data in the encryption coverage, and a transmission section that transmits the encrypted packet through SA.
