Yuquan Zhang, Lei Wei · 2015
A security scheme for wireless sensor network based grids is given through using the symmetric polynomials.The sensing equilateral hexagon is divided into a number of sections called grids in which both ordinary sensor nodes and powerful sensor nodes are distributed evenly.All sensor nodes including the powerful sensor nodes and the ordinary sensor nodes establish their shared keys through utilizing different symmetric polynomials in each grid.All powerful sensor nodes set up their shared keys through using symmetric polynomials in whole sensing area.At last, all sensor nodes in the sensing area set up their keys directly or indirectly.Analysis demonstrates the wireless sensor network security has been improved.
