Wirelesscommunication Continues to Make In-Roads into Many Facets of Our Society Andgradually Becomes More and More Ubiquitous. While, In the Past, Wirelesscommunication (As Well As Mobility) Was Largely Limited to First and Lasttransmission Hops, Today’S Wireless Networks Are Starting to Offer Purelywireless, Often Mobile, and Even Opportunistically Connected Operation. Thepurpose of This Paper Is to Examine Security and Privacy Issues In some New Andemerging Types of Wireless Networks and Identify Directions For Futureresearch. Developments In Pervasive Computing Introduced a New Worldof Computing Where Networked Processors Embedded and Distributed In Everydayobjects Communicating With Each Other Over Wireless Links. Computers In Suchenvironments Work In the Background While Establishing Connections Among Themdynamically and Hence Will Be Less Visible and Intrusive. Such a Vision Raisesquestions About How to Manage Issues Like Privacy, Trust and Identity In Thoseenvironments. In This Paper, We Review the Technical Challenges That Face Pervasivecomputing Environments In Relation to Each of These Issues. We Then Present Anumber of Security Related Considerations and Use Them As a Basis Forcomparison Between Pervasive and Traditional Computing. We Will Argue Thatthese Considerations Pose Particular Concerns and Challenges to the Design Andimplementation of Pervasive Environments Which Are Different to Those Usuallyfound In Traditional Computing Environments. to Address These C ...
