Security Management Scheme in WSN Based on the Onetime Pre-shared Key
Yu Liu · Journal of Hefei University · 2009
In the initial deploying stage of wireless sensor networks,because of not being detected or hard to break by attackers,every node has ability to resist being hijacked.Based on onetime pre-shared key,a security management scheme SMOPK,suitable for static network,was introduced.The scheme used onetime pre-shared key to perform consultation of secret key,and therefore realizing secured links between neighboring nodes and building up a secured topology which is consistent with the actual wireless topology.Analysis showed that the scheme had strong security features with low cost.
