NetEx Project Overview

NetCamo
TAMU and NSWC July 2000
2
Objectives

• Keep network activity anonymous and unobservable
• Provide QoS-guaranteed communication services
• Be upward and downward compatible with existing
  operating systems, applications, and network
  technologies
• Be scalable and evolvable

3
Approaches

• Traffic camouflaging traffic rerouting and
  padding based on real-time traffic modeling
  theory (RTMT).
• Real-time communication providing end-to-end
  delay guaranteed services based RTMT and
  efficient admission control
• Implemented both middle-ware version and
  independent station version
• Future work traffic monitoring and intrusion
  detection

NetCamo/M System

• A middle-ware solution
• Advantages
• No additional equipment
• Upward and downward compatible
• Status
• Working on MS NT workstations
• Providing both real-time and camouflaging
  services
• Demonstrated to DARPA in May 2000

NetCamo/N System

• Using independent NetCamo Stations
• No disturbance to application hosts and upward
  and downward compatible
• Status July 2000, beta version of NetCamo
  station realized on Lynux-based PCs, providing
  both IPSec and camouflaging services
