Efficient user and broadcast authentication scheme for WSNs
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014Wireless sensor networks are collections of tiny sensors working collaboratively to gather information. Two major shortcomings of today's WSNs are scarce energy and memory resources making it difficult to devise robust and effective security measures. Keyed-hash chains have been proposed as an efficient solution.

The TESLA Broadcast Authentication Protocol
2018One of the main challenges of securing broadcast communication is source authentication, or enabling receivers of broadcast data to verify that the received data really originates from the claimed source and was not modified en route. This problem is complicated by mutually untrusted receivers and unreliable communication environments where the sender ...

Efficient Broadcast Authentication in Wireless Sensor Networks
2008 IEEE Asia-Pacific Services Computing Conference, 2008Broadcast authentication is an important security primitive in wireless sensor networks. Costs of Tree- based muTESLA are rising rapidly with more senders in networks, which limit its use in large-scale networks. To removing such a limit, this paper presents a muTPCT-based broadcast authentication protocol which mainly rests on constructions of muTPC ...

BAP: Broadcast Authentication Using Cryptographic Puzzles
2007We present two broadcast authentication protocols based on delayed key disclosure. Our protocols rely on symmetric-key cryptographic primitives and use cryptographic puzzles to provide efficient broadcast authentication in different application scenarios, including those with resource-constrained wireless devices such as sensor nodes. The strong points

Localized Broadcast Authentication in Large Sensor Networks
International conference on Networking and Services (ICNS'06), 2006Although TESLA can provide the crucial broadcast authentication, it also introduces some problems (such as large verification delay) that limit its application in a large wireless sensor network due to the resource constraints. In this paper, we present a localized broadcast authentication protocol, namely L-TESLA, to address these problems.

“Authentic” talk in broadcast news: The construction of community
The Communication Review, 2001Some recent assessments of public communication have demonstrated a concern for “authentic” forms of discourse in public life. This article uses a methodology derived from conversation analysis to examine different forms of public discourse in news interviews. Previous studies taking this approach have outlined the protocols for formal news interviews,

A Practical Inter-sensor Broadcast Authentication Scheme
2007For inter-sensor broadcast authentication in wireless sensor networks, Chen et al. proposed a bootstrapping scheme which enables to save only neighboring nodes' hash-chain commitments, much fewer than whole network size, before deployment [2]. However, the scheme lacks scalability and is not tolerant for node isolation.

Pre-Distribution of Certificates for Pseudonymous Broadcast Authentication in VANET
2015 IEEE 81st Vehicular Technology Conference (VTC Spring), 2015In the context of vehicular networks, certificate management is challenging because of the dynamic topology and privacy requirements. In this paper we propose a technique that combines certificate omission and certificate pre-distribution in order to reduce communication overhead and to minimize cryptographic packet loss.
