A Pseudonym Assignment for the Last Mile Wireless Access to 4G Networks

摘要: The last mile wireless access to 4G networks is inherently vulnerable various attacks due broadcasting feature of transmission. Although most communication systems provide the security measures, they focus on protection contents a message. Therefore, header part each message including source and destination addresses transmitted in plain-text format, which can reveal information that useful an attacker. In this paper, we solve loss anonymity through novel pseudonym assignment scheme. Specifically, master node generates sets for slave nodes by using Unique Pair Sequence (UPS) first devised, assigns them node. Since every randomly uses one pseudonyms set as ID whenever it transmits message, our scheme prevent attacker from attempting traffic analysis attack.
