Due to limitations of power,computation capability and storage resources,the traditional trusted key management based on the public-key was not suitable for wireless sensor networks.To further enhance the security and connectivity for wireless sensor networks,proposed an improved key management scheme.Introduced the scheme,a random key predistribution using multiple key spaces and multipath key reinforcement was based on group-based deployment model which in the paper of DU Wen-liang.Analysis and simulations show that the scheme has lower memory and communication overheads,better ability against attacks besides good security performance.
