This paper presents a new public key distribution scheme adapted to ad-hoc networks called TAKES for Trustful Authentication and Key Exchange Scheme. Its originality lies in performing authentication and key distribution with no need for a trusted authority or access to any infrastructure-based network, thanks to the use of Cryptographically Generated Addresses. Moreover the solution is very convenient having a simple operational mode at no extra hardware cost. TAKES aims to build a trust association between a person, his/her communicating device, the IP address of the device, and his/her public key. As a direct result, new security functions like associating a misbehaving node to its owner, securing end-to-end communications through tunnels, or even implementing a light naming system can be enabled on top of ad-hoc networks. TAKES is formally proven using BAN logic and a proof-of- concept implementation demonstrates its feasibility within ad-hoc networks.
