Broadcast Security in Future Mobile Networks

Abstract

A typical broadcast authentication communication within information distribution systems is characterised by plain text communication between nodes, which do not mutually authenticate. Although, the authentication of every incoming message seems to be a very effective way to mitigate a denial of service type attack, such process results into an increase of end-to-end delay. To mitigate this drawback, the broadcast authentication protocols have been proposed. This paper introduces a new improved delay and resource enhanced DREAM (IDARED) scheme, which is based on the DoS resistant efficient authentication mechanism (DREAM) and which provides lower latency results achieved by several parameters optimisation and a split verification queue concept for the end-to-end management data traffic in the next generation femtocell (NGF).
