This paper present the designs and evaluations of an 802.11-like wireless link layer protocol that obfuscates all transmitted bits to increase privacy. This includes explicit identifiers such as MAC addresses, the contents of management messages, and other protocol fields that the existing 802.11 protocol relies on to be sent in the clear. By obscuring these fields, the authors greatly increases the difficulty of identifying or profiling users from their transmissions in ways that are otherwise straightforward.
