Abstract :
In this letter, we propose a continuous secure scheme based on two-dimensional backward hash key chains. Through detailed analysis, we show that our scheme achieves high local connectivity with a low storage overhead, and has higher network resilience against node compromise as compared with the scheme based on one-dimensional hash key chain for multiple deployment sensor networks (MDSNs).
