Authenticated Key Exchange Protocol

Affiliation-hiding authenticated key exchange protocol, also called secret handshake, makes two parties from the same organization realize mutual authentication and key agreement via public key certificates without leaking the organization information to any others. Moreover, if the peer involved in the protocol is not from the same group, no any information of the affiliation can be known. In previous secret handshakes protocols, there is a problem which is linkability. That is to say, two activities of the same people can be associated by the attackers. It is not desirable for privacy because the association may deduce it’s affiliation with some other information. In this paper, an unlinkable affiliation-hiding authenticated key exchange protocol is brought out to conquer the linkability. Security analysis is given finally.

<p>Peer to Peer (P2P) or direct connection IoT has become increasingly popular owing to its lower latency and higher privacy compared to database-driven or server-based IoT. However, wireless vulnerabilities raise severe concerns on IoT device-to-device communication. This is further aggravated by the challenge to achieve lightweight direct mutual authentication and secure key exchange between IoT peer nodes in P2P IoT applications. Physical unclonable function (PUF) is a key enabler to lightweight, low-power and secure authentication of resource-constrained devices in IoT. Nevertheless, current PUF-enabled authentication protocols, with or without the challenge-response pairs (CRPs) of each of its interlocutors stored in the verifier’s side, are incompatible for P2P IoT scenarios due to the security, storage and computing power limitations of IoT devices. To solve this problem, a new lightweight PUF-based mutual authentication and key-exchange protocol is proposed. It allows two resource-constrained PUF embedded endpoint devices to authenticate each other directly without the need for local storage of CRP or any private secrets, and simultaneously establish the session key for secure data exchange without resorting to public-key algorithm. The proposed protocol is evaluated using the Mao and Boyd logic as well as the automatic security analysis tool ProVerif to corroborate its mutual authenticity, secrecy, and resistance against replay and man-in-the-middle attacks. Using two Avnet Ultra96-V2 boards to emulate the two IoT endpoint devices of a network, a physical prototype system is also constructed to demonstrate and validate the feasibility of the proposed secure P2P connection scheme.</p>
