Efficient Key Distribution Schemes for Large Scale Mobile Computing Applications

Mahalingam Ramkumar

Abstract: In emerging networks consisting of large-scale deployments of mobile devices, efficient security mechanisms are required to facilitate cryptographic authentication. While computation and bandwidth overheads are expensive for mobile devices, the cost of storage resources continue to fall at a rapid rate. We propose a simple novel key predistribution scheme, \textit{key subset and symmetric certificates} (KSSC) which can take good advantage of inexpensive storage resources, and has many compelling advantages over other approaches for facilitating ad hoc establishment of pairwise secrets in mobile computing environments. We argue that a combination of KSSC with a variant of an elegant KDS proposed by Leighton and Micali is an appealing choice for securing large scale deployments of mobile devices.
