Abstract
In heterogeneous sensor networks (HSNs), which use existing key predistribution schemes, network security will significantly decline with time. In this paper, a continuous secure scheme is proposed based on two-dimensional backward key chains. In the scheme, powerful sensors do not need to be equipped with tamper-resistant hardware. Analysis and simulations indicate that the proposed scheme can significantly improve the performance of existing schemes in resilience against node capture attacks throughout the lifecycle of static HSNs.
