Information Survivability for Mobile Wireless Systems

VOLUME 12, NUMBER 1, 2000 LINCOLN LABORATORY JOURNAL 65 I  encompasses many aspects of security and reliability for computers and networks. Information survivability is more than just preventing computer break-ins and protecting secret information from prying eyes. Systems must be robust; they must be able to continue to operate despite successful attacks that may compromise portions of the system. Maintaining the security and survivability of mobile wireless systems is a complex challenge. Wireless communication links typically have lower bandwidth and reliability than the wire or fiber-optic links used in conventional networks because they are more susceptible to communication errors caused by noise and interference. Radio links can fade as computers in the network move in and out of communication range with their neighbors. Communication can be cut off altogether if computers move behind obstacles, such as buildings or hills. Information Survivability for Mobile Wireless Systems
