Anonymous Communication in Ubiquitous Computing Environments

摘要: Wireless networks such as WLANs which have already been commonplace will play an important role in providing the last mile access for ubiquitous computing environments. However, wireless technologies are accompanied with some security vulnerabilities that stem from broadcasting medium. Although most of can be solved by existing countermeasures, there still exists vulnerability a message header. In networks, header part each message, including source and destination addresses, is transmitted plain-text format. This hole adversaries collecting revealed information traffic analysis attack breach privacy transmitter receiver. this paper, we focus on describing solution to problem, namely, undesirable loss privacy. Our main idea integrate address conventional Message Authentication Code (MAC) replace both fields MAC integrated code called Address-embedded (AMAC). Through detailed performance our scheme, show AMAC scheme guarantee network while provable level less overhead.
