ABSTRACT
In this chapter, we discuss issues and survey current solutions in securing ad hoc wireless networks. The characteristics of ad hoc networks render the trust a host could place on other hosts and a network more precarious than in a conventional network. Any viable security approach ought to address trust concerns for specific applications. As examples, we look at three specific issues and their current proposed solutions: a transient association as host access control policy for mobile appliances, link-by-link and end-to-end authentication for securing routing in open networks, and split control for a centralized service or distributed services for survivable services in a rapidly changing network.
