We introduce a novel cryptographic paradigm of broadcast authentication with “preferred” verifiers (BAP). With BAP, the message source explicitly targets a set of one or more verifiers. For an attacker, forging authentication data of a source, for purposes of fooling preferred verifiers may be substantially more difficult than fooling other (non-preferred) verifiers. We investigate broadcast au...

Broadcast authentication is a fundamental security service in distributed sensor networks. This paper presents the development of a scalable broadcast authentication scheme named multi-level μTESLA based on μTESLA, a broadcast authentication protocol whose scalability is limited by its unicast based initial parameter distribution. Multi-level μTESLA satisfies several nice properties, including ...

This paper deals with simulation of the broadcast authentication protocols using Colored Petri Nets and further optimizations in Matlab environment. Typical application of broadcast authentication protocols can be configurations where only one transmitter with multiple recipients exists (such as message exchange in sensor networks routing protocols, or the leader election process in sensors net...

One-time signature schemes have found numerous applications: in ordinary, on-line/off-line, and forward-secure signatures. More recently, they have been used in multicast and broadcast authentication. We propose a one-time signature scheme with very efficient signing and verifying, and short signatures. Our scheme is well-suited for broadcast authentication, and, in fact, can be viewed as an im...

In wireless sensor networks (WSNs), broadcast authentication allows only legitimate users (or senders) to disseminate messages into the networks. μTESLA [14] is the first broadcast authentication scheme for WSNs. It allows only few users, mainly several base stations, to broadcast messages, but in reality there are many scenarios that require a large number of dynamic users (mobile sinks or use...

a broadcast authentication protocol enables the receivers to verify that a received packet was really sent by the claimed sender. Data confidentiality, authenticity, integrity, and non repudiation are basic concerns of securing data delivery over an insecure network. Large and distributed systems with time critical applications require immediate and secure authentication of command and control ...

In wireless sensor networks (WSN’s), the broadcast authentication is a critical security service, as it helps users to broadcast the WSN in an authenticable way. μ TESLA and MULTILEVEL μ TESLA are symmetric key based schemes, that have been introduced to provide such services for WSNs, but even they suffer from serious DoS attacks due to the delay in message authentication. Hence in order to ov...

The current mobile broadcast systems do not provide efficient solution for consumption of service and content based on the user identity card such as a smartcard. This prevents users from consuming broadcast service and contents independent of a specific terminal (e.g., the one used for registration or purchase). To provide usage of broadcast services based on the user identity card, mutual aut...

This study investigates the broadcast/multicast authentication problems in wireless sensor networks (WSNs), particularly sensor nodes broadcast authentication and outside user authentication, and proposes efficient and secure solutions for them. The low cost and immunity from cabling have become motivations for many applications of WSNs, for instance, the forest fire alarm, the intelligent traf...
