Per-packet authentication is a powerful way to authenticate the user. Other authentication mechanisms (e.g. password authentication) verify the user at login time only while per-packet authentication verifies all packets coming from that user. Since every packet is authenticated repeatedly, inserting a fake packet or masquerading as a legitimate user is effectively prevented. Existing techniques for per-packet authentication such as IPSec or PLA, however, is either too expensive or not strong enough. We propose to include biometric data of the user in all packets for per-packet authentication. By collecting the user's biometric data periodically and physically from the user during the session and including it in all packets, we believe that we can provide a cheaper and more secure way of per-packet authentication. A random portion of the biometric data is extracted and used to digest the IP datagram. This technique allows us to control the size of the biometric data and to protect its contents from eavesdropper. This paper explains about the technique and provides experimental results.
