A Research on Key Management in Wireless Sensor Networks

With the constant development of wireless sensor networks technology, the expanding application scope and the increasing processing power of sensor nodes, there are more and more data collected and processed through the sensor, thus ensuring the security of information transmission between nodes is in urgent needs. The secure application of wireless sensor networks has become a hot technology. This paper mainly expounds the key management schemes of wireless sensor networks, and analyzes the mainstream key management schemes.
