In this paper, we present the design of SLEACH, asecure extension for the LEACH protocol. We divide SLEACH into four phases and fit inexpensivecryplp-graphic operations to each part of the protocol functionality to create an efficient,practical protocol. Then we give security analyses of SLEACH. Our security analyses show that ourschemeis robust against any external attacker or compromised nodes in the sensor network.展开更多
