Wireless networks and security might be considered an oxymoron. Indeed it is
hard to believe in security when it is so easy to access communication media such as
wireless radio media. However, the research community in industry and academia
has for many years extended wired security mechanisms or developed new security
mechanisms and security protocols to sustain this marriage between wireless/mobile
networks and security. Note that the mobile communication market is growing
rapidly for different services and not only mobile phone services. This is why
securing wireless and mobile communications is crucial for the continuation of the
deployment of services over these networks.
