Security Enhancement of First Mile Wireless Access with Optimal QoS through Anonymity in Convergence Network

摘要: The first mile wireless access of convergence networks is prone to various attacks due the broadcasting feature transmission. Most existing security measures focus on protection message contents, leaving header part in plain text. Therefore, that has source and destination address, when transmitted text, can reveal information be useful for traffic analysis attack. In this paper, a master node generates pseudonym sets slave nodes by using Unique Pair Sequence (UPS), assigns each set itself. assigned are all nodes. Each uses an address randomly picked from as while transmitting message, avoiding For integrity instead allocating separate bits Message Authentication Code (MAC) frame, selected set, depending value generated hash-keyed function, called Address Embedded (AMAC) followed. Since AMAC does function MAC includes it used transmit anonymously well authenticate message. AMAC, anonymous scheme where additional avoided compared with results obtained simulating scenarios ZIGBEE WiMax OPNET 14.5. simulation show performs better than terms QoS metrics also.
