QUANTUM SECURE COMMUNICATION FOR WIRELESS SENSOR NETWORKS

According to the security requirement in sensor networks, we propose a quantum secure communication protocol based on authentication for wireless sensor networks (WSN). In authentication process, we use forward shared randomly angles sequences to encrypt our GHZ states, then distribute GHZ states, user can identify each other by comparing the results of each other. It's secure and realize easily. In wireless communication protocol, consider the realistic facts in WSN; we define the third party (Base station) two particles entanglement with others per GHZ state, which improve the. transmission efficiency. Analysis shows this protocol is secure against the eavesdropping and disguising attacks.
