An Enhanced Protocol for Source Authentication in Sensor Networks

An enhanced design based on double-chain structure is presented to enable TESLA/μTESLA to be suitable to narrow-bandwidth,memory-limited and computational-resource-constrained micro-sensors,and with this design method,the calability of TESLA/μTESLA is significantly improved to suit large-scale sensor networks.This paper gives the enhanced design in detail, and discusses its implementation and further optimizations.
