摘要

A scheme for WSNs (wireless sensor networks) security is given by dividing sensing tetrahedron into clusters and using the symmetric polynomials in this paper. The sensing tetrahedron is divided into a number of small grids. All those sensor nodes, both ordinary sensor nodes and heterogeneous sensor nodes are distributed in the sensing tetrahedron. In a grid, all ordinary sensor nodes and heterogeneous sensor nodes establish their shared keys through using the symmetric polynomials. All the heterogeneous sensor nodes establish their shared keys through using the symmetric polynomials. At last, all sensor nodes establish their keys directly or indirectly in the whole sensing tetrahedron. Analysis and comparison demonstrate this scheme enhances the WSN security, has good network connectivity, saves node storage, reduces network computing load, and extends the network lifetime.
