Wireless ad hoc networks have emerged as a new information-transmission paradigm based on collaborative efforts of multiple self-organized mobile nodes. Without the support from any fixed infrastructure, this type of network provides an extremely flexible method for establishing communications in situations where geographical or terrestrial constraints demand totally distributed network system. While the inherent characteristics of an ad hoc network make it useful for many applications, they also bring in a lot of research challenges. One of the important issues is the security, since conventional security approaches adopted for traditional networks are not directly applicable to ad hoc networks. Secure ad hoc network is critical to the development of any real application of wireless ad hoc networks. In this dissertation, we attempt to develop an integrated and distributed security scheme with resource-awareness to enhance the security of ad hoc networks. Our scheme can be logically divided into two parts. An efficient intrusion prevention mechanism is developed to prevent the various attacks from external intruders, and an intrusion detection mechanism is used to provide a second line of defense for the misbehaviors of internal intruders. In the intrusion prevention mechanism, the identity-based cryptography, bivariate polynomial-based pairwise key and one way hash chain techniques are used to provide various security goals, such as availability, integrity, confidentiality, authentication and non-repudiation. Considering the self-organizing property of ad hoc networks, the intrusion detection is implemented in a distributed fashion, in which the behavior of each node is monitored and analyzed using a cooperative functions involved in the network. The intrusion detection scheme can detect both the internal and external attacks, but it pays more attention on the attacks that cannot handled by the intrusion prevention approach, and the result of intrusion detection would further guide and help the intrusion preventon mechanism to efficiently isolate the malicious nodes.The proposed security scheme can be incorporated into the existing routing protocols to enhance the overall security, at the same time keep a minimal overhead to the routing protocols.
