Technical Approach

• The SPREAD group communication system:

  • Overlay network architecture.
  • Performance improvements.

• The QLIQUES protocol suite for distributed group key management:

  • Provably secure.
  • Decentralized.
  • Contributory in nature.

• Dual-track development which explores two architectures for group security:

  • Layered architecture providing flexibility and faster implementation.
  • Integrated architecture providing an order of magnitude performance gains for multi group environments.
