PROBLEM TO BE SOLVED: To acquire effective network security, which maximizes the utilization of existing protocols, such as TLS and TCP, against session destruction due to unauthorized data injection by a third person, such as DoS attack. SOLUTION: It is provided with an architecture for packet authentication, which includes an input part 322 that can receive packets, a packet that comprises at least one transmission, a session and a presentation header part, and a transmitting agent 312 that calculates a first message authentication code for packet authentication based on at least some packet contents and compares the first message authentication code with a second message authentication code in at least one transmission, a session and a presentation header part.
