An Authentication Protocol Based on Batch Verification for Heterogeneous WSN
Tao Ma · Chuangan jishu xuebao · 2011
To the question that verification protocol based on ECC of WSN requires huge computational,an authentication protocol based on batch verification for heterogeneous WSN is proposed.Considering the heterogeneous characteristics of WSN,the protocol uses ECDSA to sign messages and takes joint sparse coefficient to verify signatures.Simulation analysis shows that the protocol can reduce the computational complexity of multi-scalar multiplications in batch verification effectively,and the efficiency of digital signature verification is improved greatly.
