Anti-jamming timing channels for wireless networks [PDF]
Proceedings of the first ACM conference on Wireless network security, 2008 Wireless communication is susceptible to radio interference, which prevents the reception of communications. Although evasion strategies have been proposed, such strategies are costly or ineffective against broadband jammers. In this paper, we explore an alternative to evasion strategies that involves the establishment of a timing channel that exists ...
