Authenticating broadcast packet communications poses a challenge that cannot be addressed efficiently with public key signatures on each packet, or securely with the use of a pre-distributed shared secret key, or practically with unicast tunnels. Unreliability is an intrinsic problem: many broadcast protocols assume that some information will be lost, making it problematic to amortize the cost ...

Timed Efficient Stream Loss-tolerant Authentication (TESLA) and digital signature are security implementations of broadcast authentication in Wireless Sensor Networks (WSNs). Both approaches, however, are considered vulnerable to DoS attacks. Encountering this attack requires a scheme that addresses two security measures: prevention and detection.. This paper provides a hybrid solution between ...

At present, wireless sensor networks have become one of the indispensable infrastructures in people’s lives. Considering frequent mobility network nodes, an efficient lattice-based random broadcast authentication protocol is proposed. The security proposed based on SIS problem which helps to resist against quantum attacks. In this paper, we propose two forms authentication, that is, one-to-many...

Traditional point-to-point message authentication systems have been extensively studied in the literature. In this paper, we consider authentication systems for group communication. The basic primitive is a multireceiver authentication system with dynamic senders (DMRA-code). In a DMRA-code any member of the group can broadcast an authenticated message to the rest of the group such that every o...

Broadcast communications are critically important, In vehicular networks. It becomes a challenging problem to design a broadcast authentication scheme for secure vehicular networks. Especially when a large number of beacons arrive in a short time, vehicles are vulnerable to computation-based Denial of Service (DoS) attacks that excessive signature verification exhausts their computational resou...

The security services of authentication and confidentiality are of significant importance to ensure secure communication in any network. The decentralized nature and the broadcast medium of communication of wireless ad hoc networks results in unique challenges in realizing the services of authentication and data confidentiality. In this chapter, We first highlight the issues relating to authent...

Broadcast authentication is a critical security service in wireless sensor networks (WSNs), as it allows a sender to broadcast messages to multiple nodes in an authenticated way. Symmetric key based schemes such as μTESLA and μTESLA-like schemes have been proposed to provide such services for WSNs, however, the life-time of these schemes is constrained by the length of the key chains. To addres...

In order to achieve the multi-user broadcast authentication in WSNs (Wireless Sensor Networks) defending against DoS (Denial-of-Service) attack, a multi-user broadcast authentication protocol in WSNs was proposed based on the improved ECDSA (Elliptic Curve Digital Signature Algorithm) with partial message recovery. The authenticity of the user public key is verified by using bloom filter, which...

Due to the low-cost nature of sensor network nodes, we cannot generally assume the availability of a high-performance CPU and tamperresistant hardware. Firstly, we propose a reliable broadcast message authentication working under the above-mentioned circumstances. The proposed scheme, although based on symmetric cryptographic primitives, is secure against anyone who knew the message authenticat...

E-Learning enables the users to learn at anywhere at any time. In E-Learning systems, authenticating the E-Learning user has security issues. The usage of appropriate communication networks for providing the internet connectivity for E-learning is another challenge. WiMAX networks provide Broadband Wireless Access through the Multicast Broadcast Service so these networks can be most suitable fo...
