Security Issues and Challenges (SIC) of Ad-hoc Networking.

Abstract

As the approach of ad hoc networking varies from traditional networking approaches, the security aspects that are valid in the conventional wired networks are not fully applicable in the context of ad hoc networks. While the basic security requirements such as confidentiality and authenticity remain, the ad hoc networking approach restricts the set of applicable security mechanisms to be used since the level of security and the performance are related to each other and must be carefully balanced. The security goals and challenges that the field of ad hoc networking faces are explored in more detail. An overview of the most important active attacks is included. Some of the most important security schemes are presented in order to illustrate common approaches that are currently followed to ensure network security in infrastructure less networks. The protected resourceful Ad hoc Distance vector routing protocol (SEAD)[2] employ the use of hash chains to substantiate hop counts and sequence numbers. SEAD[2] is based on the design of the proactive ad hoc routing protocol DSDV[9]. The final secure routing protocol to be presented is the Secure Routing Protocol (SRP).
