Broadcast Authentication in Group Communication
Lecture Notes in Computer Science, 1999Traditional point-to-point message authentication systems have been extensively studied in the literature. In this paper we consider authentication for group communication. The basic primitive is a multireceiver authentication system with dynamic sender (DMRA-code).

Broadcast Authentication and Broadcast Encryption
2014Broadcast authentication schemes that employ only symmetric PRFs include certificates-based schemes like one-time-signatures (OTS), and timed efficient stream loss tolerant authentication (TESLA), and identity-based schemes based on probabilistic subset allocation.

Authenticated Broadcast Encryption Scheme
21st International Conference on Advanced Information Networking and Applications Workshops (AINAW'07), 2007With the advancement of wireless networks and mobile access devices such as cell phones and PDAs, multimedia services could be offered through wireless broadcast networks to these mobile devices. Therefore, there is a need to securely deliver multimedia content/data to many users over an insecure channel.

A survey of broadcast authentication schemes for wireless networks
Ad Hoc Networks, 2015With the increase in the usage of wireless networks and their applications where broadcast transmission is widely used, it has become critical to authenticate broadcast messages. Several broadcast authentication techniques are currently available. However, no scheme is ideal for all broadcast transmission applications.

Attacking NTP's Authenticated Broadcast Mode
ACM SIGCOMM Computer Communication Review, 2016We identify two attacks on the Network Time Protocol (NTP)'s cryptographically-authenticated broadcast mode. First, we present a replay attack that allows an on-path attacker to indefinitely stick a broadcast client to a specific time. Second, we present a denial-of-service (DoS) attack that allows an off-path attacker to prevent a broadcast client ...

Practical broadcast authentication in sensor networks
The Second Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services, 2005Broadcast authentication is a critical security service in sensor networks; it allows a sender to broadcast messages to multiple nodes in an authenticated way. /spl mu/TESLA and multi-level /spl mu/TESLA have been proposed to provide such services for sensor networks.

On Broadcast Authentication in Wireless Sensor Networks
IEEE Transactions on Wireless Communications, 2006Broadcast authentication is a critical security service in wireless sensor networks (WSNs), since it enables users to broadcast the WSN in an authenticated way. Symmetric key based schemes such as muTESLA and multilevel muTESLA have been proposed to provide such services for WSNs; however, these schemes all suffer from serious DoS attacks due to the ...

Enhancing broadcast authentication in sensor networks
Proceedings of the 2010 Spring Simulation Multiconference, 2010Due to the nature of wireless sensor networks, security is a critical problem that needs to be further researched and developed. Resource constrained and usually unattended sensors are much vulnerable to malicious attackers that may impersonate the senders by altering broadcast messages.

To design a broadcast authentication protocol that provides real-time authentication, robustness to packet loss, efficient verification, and scales to large audiences, we invent a new signature algorithm. We call our new algorithm the BiBa signature, short for Bins and Balls signature.

Flooding-resilient broadcast authentication for VANETs
Proceedings of the 17th annual international conference on Mobile computing and networking, 2011Digital signatures are one of the fundamental security primitives in Vehicular Ad-Hoc Networks (VANETs) because they provide authenticity and non-repudiation in broadcast communication. However, the current broadcast authentication standard in VANETs is vulnerable to signature flooding: excessive signature verification requests that exhaust the ...
