“…Former implementations of the AQ-protocol only focused on the Intel Mote 2 platform or the Telos B platform, see [4], [2] and [3]. We have implemented the fixed key establishment and the presented ephemeral key establishment on a MICAz platform manufactured by Crossbow Technologies Inc. [13].…”

Public key cryptography based on elliptic curves is a promising foundation for energy-scarving pairwise key establishment in wireless sensor networks. Focusing on the Diffie-Hellman key-agreement, identity-based schemes can be applied to provide mechanisms for authentication. The AQprotocol presented by Arazi et al. introduces such a key establishment supporting fixed as well as ephemeral keys.In this paper we review two known attacks of the ephemeral key establishment of this protocol. We introduce a new ephemeral key establishment for the AQ-protocol to fix these problems and analyze the proposed approach from a security perspective. We illustrate its feasibility for wireless sensor networks by presenting implementation results for the MI-CAz platform using TinyOS 2.x.

A self-certi ed DH xed key-generation is achieved by the following two steps [28] : (1) N i and N j exchange the pairs (ID i ; U i ) and (ID j ; U j ), respectively, and (2) N i and N j generate the session-key,…”

“…Ephemeral key-generation is more secure and is generally preferred when time and resources permit. A selfcerti ed DH ephemeral key-generation is also possible ( [28]), but would consume three times more energy when compared to the xed key case. In order to establish an ephemeral key, the two nodes can utilize bits in message m, (generated by Bob) excluding the rst x least signi cant bits.…”

Abstract-The challenging characteristics of sensor nodes, including the constrained resources, the ad-hoc nature of their deployment and the vulnerability of wireless media, pose a need for unique security solutions. The advantages of Public Key Cryptography (PKC) for sensor network security are widely acknowledged and include resilience, scalability and decentralized management. Recent work has indicated that PKC is feasible in the wireless sensor network (WSN) environment, paving the way for many new security services and opportunities. However, the computational effort involved in performing PKC operations remains substantial. From an energy consumption perspective, it is imperative that the processing and communication resources be utilized only when required. To that end, PKC implementations are more vulnerable to Denial of Service (DoS) attacks, when compared to traditional security methods that require less resources. In particular, if a malicious party attacks a sensor node by repetitive requests to establish a key, the resources of the attacked node can be exhausted quite rapidly. In this paper, we propose a novel RSA-based framework for combating DoS attacks in WSN by ensuring that the malicious party will exhaust its resources prior to exhausting those of its counterparts. Under the proposed approach, the mathematical operations performed by the malicious party require two or three orders of magnitude more resources than those required by the attacked party. We also present three methodologies for establishing an ephemeral key, in which the proposed DoS mitigation mechanism is an embedded component. Implementation results on the Intel Mote 2 platform substantiate the clear advantages of the proposed method.
