This research focuses on developing a set of secure communication network testbeds and using them to measure the overhead of IP Security (IPSec) for email and web applications. The network testbeds are implemented using both wireline and wireless technologies. The testing involves a combination of authentication algorithms such as Hashed Message Authentication Code-Message Digest 5 (HMAC-MD5) a...

One of the most effective techniques to prevent the tainted and adversary messages from being forwarded in wireless sensor network is message authentication. Message authentication is a short piece of information used to offer integrity, validate a message and legitimacy declarations on the message. In this paper, we have used the Source Anonymous Message Authentication scheme (SAMA) that is on...

The Controller Area Network (CAN) is the most common network system in automotive systems. However, standardized design of a CAN protocol does not consider security issues, so it vulnerable to various attacks from internal and external electronic devices. Recently, in-vehicle often connected systems, including Internet, can result an unwarranted third-party application becoming attack point. Me...

TESLA, the Timed Efficient Stream Loss-tolerant Authentication protocol, provides source authentication in multicast scenarios. TESLA is an efficient protocol with low communication and computation overhead that scales to large numbers of receivers and also tolerates packet loss. TESLA is based on loose time synchronization between the sender and the receivers. Source authentication is realized...

This document defines Remote Authentication Dial In User Service (RADIUS) support for the Extensible Authentication Protocol (EAP), an authentication framework which supports multiple authentication mechanisms. In the proposed scheme, the Network Access Server (NAS) forwards EAP packets to and from the RADIUS server, encapsulated within EAP-Message attributes. This has the advantage of allowing...
