A Two-Layer Key Scheme for Wireless Detector Networks
In an oversized scale sensing element network, it’s impracticable to assign a novel Transport Layer Key (TLK) for every try of nodes to produce the end-to-end security attributable to the large memory price per node. Thus, standard key establishment schemes follow a key pre-distribution approach to determine a Link Layer Key (LLK) infrastructure between neighboring nodes and admit multi-hop methods to produce the end-to-end security. Their drawbacks embrace vulnerability to the node compromise attack, massive memory price and energy unskillfulness with in the key institution between neighboring nodes. In this paper, the authors propose a novel key establishment scheme called LAKE, for sensor networks.
