A survey of anonymity in wireless communication systems [PDF]
Security and Communication Networks, 2008 AbstractAnonymity is an important security aspect of wireless communications and has continuously attracted significant attention. Implementing anonymity of mobile users not only protects their privacy but also reduces the chances of attacks based on impersonation; therefore security can be improved. Untraceability is a related issue to anonymity. If a
