Wireless Communications have become a very attractive and interesting sector for the provision of electronic services. Mobile networks are available almost anytime, anywhere and the user’s acceptance of wireless hand-held devices is high. The services, are offered, are strongly increasing due to the different large range of the users’ needs. They vary from simple communications services to special and sensitive purposed applications such as electronic commerce and digital cash. It is obvious that in future wireless protocols and communications environments (networks), security will play a key role in the transmitted information operations. This paper summarizes key issues that should be solved for achieving the desirable performance in security implementations and focuses alternative integrations approaches for wireless communications security. It gives an overview of the current security layer of wireless protocols and presents the performance characteristics of implementations in both software and hardware. We also propose some efficient methods to implement security schemes in wireless protocols with high performance. The purpose of this paper is to provide the state-of-the-art and research trends on implementations of wireless protocols security for current and future wireless communications.
