In order to reduce communication cost and computation cost in wireless sensor networks( WSN),an efficient broadcast authentication scheme based on pairing-based cryptography with message recovery is proposed.This mechanism does not require the simultaneous transmission of the original signature information and the new generated signature information.Authentication /message recovery process can automatically restore the original signature information.Firstly,the system is initialized,the base station generates system parameters.Then,users get the key from the base station,and access WSN.Finally,when the users need to broadcast messages to WSN,the identity-based signature( IBS) protocol based on message recovery mechanisms is used to write the signed message to broadcast.Experimental analysis show that compared with IMBAS and IDBAS,the message size of the protocol is decreased by 30% and 22.3% respectively.On the 112 bit security level,the total energy consumption is reduced by at least about 30%.It has at least 15% reduction in total energy consumption on the 80 bit security level.
