DIMACS Workshop on Mobile and Wireless Security 
     November 3 - 4, 2004
     DIMACS Center, Rutgers University, Piscataway, NJ

      Bill Arbaugh, University of Maryland, waa at cs.umd.edu 
Presented under the auspices of the Special Focus on Communication
Security and Information Privacy.


The rapid growth of both voice and data wireless communications has
resulted in several serious security problems in both the voice and 
data spaces. Unfortunately, many of the early security mistakes made 
with wireless voice communications were repeated with data
communications, i.e. the use of flawed authentication and
confidentiality algorithms. For example, the standards committee for 
802.11 left many of the difficult security issues such as key
management and a robust authentication mechanism as open problems. 
This has led many organizations to use either a permanent fixed
cryptographic variable or no encryption with their wireless networks. 
Since wireless networks provide an adversary a network access point
that is beyond the physical security controls of the organization, 
security can be a problem. Similarly, attacks against WEP, the
link-layer security protocol for 802.11 networks can exploit design 
failures to successfully attack such networks. This workshop will 
focus on addressing the many outstanding issues that remain in
wireless cellular and WLAN networking such as (but not limited to):
Management and monitoring; ad-hoc trust establishment; secure roaming
between overlay networks; availability and denial of service
mitigation; and network and link layer security protocols. We will 
seek to extend work on ad hoc networking from a non-adversarial
setting, assuming a trusted environment, to a more realistic setting
in which an adversary may attempt to disrupt communication. We will
investigate a variety of approaches to securing ad hoc networks, in 
particular ways to take advantage of their inherent redundancy 
(multiple routes between nodes), replication, and new cryptographic 
schemes such as threshold cryptography.
