NETp1-10: A New Security Architecture for Personal Networks

The concept of personal networks is very user- centric and representative for the next generation networks. However, the present security mechanism is not considering at all what happens whenever a mobile node (device) is compromised, lost or stolen. This kinds of leakage of stored secrets has been a great danger in the field of communication security since it sometimes leads to the complete breakdown of the intended security level. In order to solve the problem, we propose a 3-way leakage-resilient and forward-secure authenticated key exchange (3LRFS-AKE) protocol and its security architecture for personal networks. The 3LRFS-AKE protocol guarantees not only forward secrecy of the shared key between device and its server but also a new additional layer of security against leakage of stored secrets. The security architecture includes two different types of communications: PN wide communication and communication between P-PANs of two different users.
