Data Management
New Security Issuesin Mobile and Wireless Networks
• Location-based Access Control– If Alice Is in Country P, She Can Do X– If Alice Is in Country Q, She Can Do Y
– GPS? Need Tamper-Resistant Hardware…
• Group-Based or Group-Centric Security– How Can One “Speak” As a Group or a Fraction Thereof?– Admitting New or Expelling Existing Members– Issuing, Re-issuing Credentials
• Secure Commun. in Constantly Changing Groups– Group Needs Common Key: Key Distribution/Agreement– Authentication of Membership
– e.g., Alice Is in This ad Hoc Net Cluster at This Time

Mobile Code-Based Client-Serverfor the Active Web
• Client Is Extended by Injecting Code Into Internet• Extension Runs at Intermediate Server
– Higher Performance, Greater Reliability– Liberated From Client Device, Bypasses Wireless Link
• Current implementation: Java, JINI
