The Dangers of Mitigating Security Design Flaws: A Wireless Case Study
Found in: IEEE Security and Privacy
By Nick L. Petroni Jr., William A. Arbaugh
Issue Date:January 2003
pp. 28-36
<p>Mitigating design flaws often provides the only means to pro0tect legacy equipment, particularly in wireless local area networks. A synchronous active attack against the wired equivalent privacy protocol demonstrates how mitigating one flaw or att...
 
Toward Secure Key Distribution in Truly Ad-Hoc Networks
Found in: Applications and the Internet Workshops, IEEE/IPSJ International Symposium on
By Aram Khalili, Jonathan Katz, William A. Arbaugh
Issue Date:January 2003
pp. 342
Ad-hoc network - and in particular wireless mobile ad-hoc network - have unique characteristic and constraint that make traditional cryptographic mechanisms and assumptions inappropriate. In particular, it may not be warranted to assume pre-existing shared...
