  18. Analysis • Connectivity

  19. Analysis • Resiliency

  20. Comparison

  21. Conclusions • Original contribution: • Introduce a grid-based key pre-distribution scheme that utilizes the notion of plats on grid • Plat-based polynomial assignment • The advantages of the proposed scheme • Guarantees higher connectivity • More possible intermediate nodes, better resiliency

  22. Comment • In the Key Establishment phase, the authors do not describe how the sensor node find the intermediate node for indirect key establishment.
