Key management with group-wise pre-deployed keying and secret sharing pre-deployed keying

摘要

In wireless sensor networks, the key deployment problem has received little attention, whereas it is in fact fundamental, heavily involving crucial (scarce) resources of ad-hoc networks, such as memory and energy availability. We first briefly survey the state-of-the art of key deployment strategies that are amenable to ad-hoc network. Then we proposed two possible methods and we shortly investigate their space and computational complexity.
