A Key Dynamic Pre-distribution Scheme in Wireless Sensor Networks
Zhang Lian-tang · Journal of Pingdingshan University · 2007
In order to achieve secure communication in wireless sensor networks,the messages sent among sensor nodes must be encrypted and authenticated.So,key distribution and management become the fundamental problems.The author of this paper analyzes the random pair-wise keys scheme and its deficiency,combines it with the key pre-distribution using deployment knowledge scheme which is improved,and proposes a new key dynamic pre-distribution scheme.
