Abstract: The current wireless sensor network(WSN) broadcast authentication protocol based on onetime signature(OTS) can hardly meet the requirement of large-scale sensor networks,especially that of multi-sender networks,owing to its high cost of storing and communicating.To reduce the size of private-key and public-key of HORS,a scheme named assistant-key based-onetime signature(AKB-OTS) is presented which introduces an assistant-key and Merkle tree mechanism,and a broadcast authentication protocol for multi-sender sensor networks based on AKB-OTS is also presented.Analyses and experiments show that the proposed protocol is low in overhead consumed by computation,communication and storage,can resist attacks including brute-force,chosen message and DoS,and is more applicable to large-scale multi-sender sensor networks.
