  1. SECURITY IN MOBILE NETWORKS Bharat Bhargava CERIAS and Computer Sciences Departments Purdue University, W. Lafayette, IN 47907 bb@cs.purdue.edu Supported by CERIAS & NSF grants CCR-0001788 and CCR-9901712.

  2. Research Ideas • Integrate ideas from Science and Engineering of security and fault-tolerance. Examples: • Need to provide access to information during failures  need to disallow access for unauthorized users. • Duplicate routers & functions, duplicate authentication functions, duplicate secrete session key database, secure database that provides public keys. • Auditing, logging, check-pointing, monitoring, intrusion detection, denial of service. • Adaptability: • Adapt to timing, duration, severity, type of attack. • Election Protocols – selection of back-up base station.

  3. Research Ideas • Quorums (Access Control) • Check pointing (Intrusion Detection) • Adaptability (Type, Duration, Severity, Timing, Extent) • Functional/Operational failure (Denial of Service)

  4. Research Ideas • Replication & Versions • ACID properties • Reliability, Availability, Safety, Security, Dependability, Survivability • Security VS. Privacy

  5. Research Ideas • Aggregation and Generalization • Exaggeration and Misleading • Anonymity • User Profiles • Experiments (Cost of Security)
