Xuemai Gu · Chuangan jishu xuebao · 2007
In security construction of Wireless Sensor Network system(WSNs) key pre-distribution algorithm is in a important position. However the present key pre-distribution algorithms trade-off among of connectivity, resilience against node capture and storage, communication and computation overload. It is difficult to make all performance ideal. Therefore this paper presents a new method of key pre-distribution by using deployment knowledge and limit security of key space in combination model based on analyzing all kinds of typical key pre-distribution algorithms features in detail. Theory analysis and simulation prove that this method can get perfect security resilience in the condition of taking up little EMS and overload, local complete connection.
