Testbed evaluation of Lightweight Authentication Protocol (LAUP) for 6LoWPAN wireless sensor networks

Abstract

Summary 6LoWPAN networks involving wireless sensors consist of resource starving miniature sensor nodes. Since secured authentication is one of the important considerations, the use of asymmetric key distribution scheme may not be a perfect choice. Recent research shows that Lucky Thirteen attack has compromised Datagram Transport Layer Security (DTLS) with Cipher Block Chaining (CBC) mode for key establishment. Even though EAKES6Lo and S3 K techniques for key establishment follow the symmetric key establishment method, they strongly rely on a remote server and trust anchor. Our proposed Lightweight Authentication Protocol (LAUP) used a symmetric key method with no preshared keys and comprised of four flights to establish authentication and session key distribution between sensors and Edge Router in a 6LoWPAN environment. Each flight uses freshly derived keys from existing information such as PAN ID (Personal Area Network IDentification) and device identities. We formally verified our scheme using the Scyther security protocol verification tool. We simulated and evaluated the proposed LAUP protocol using COOJA simulator and achieved less computational time and low power consumption compared to existing authentication protocols such as the EAKES6Lo and SAKES. LAUP is evaluated using real‐time testbed and achieved less computational time, which is supportive of our simulated results.

An Edge-Fog Secure Self-Authenticable Data Transfer Protocol

“…DTLS is based on TLS with minimal changes caused by the nature of the underlying UDP protocol. As long as DTLS is only an adaptation of TLS protocol for use with unreliable transport and was never designed to consider all the special demands of IoT and constrained devices, the new versions of DTLS, which are more suitable for constrained environments, are emerging [29,30], and new lightweight authentication protocols are being proposed [31]. Despite these efforts, the optimization of DTLS for constrained environments is still an open issue [32,33].…”
