specific Embodiment

[0070] The sensor network node 100 uses the first quantum communication system 101 to establish a quantum communication channel and receives the key required for wireless communication, uses the first encryption and decryption system 102 to encrypt plaintext and decrypt ciphertext, and uses the first wireless communication system 103 to To transmit ciphertext and negotiate communication parameters, use the first data collection and processing system 104 to collect the required environmental data and convert the data into digital signals or required formats. It adopts a 32-bit wireless MCU based on STM32W108, which complies with IEEE802.15.4 / Zigbee standard specifications; supports random selection of 11 to 26 channels; built-in SimpleMac protocol stack, and supports star network and point-to-point network construction.

[0071] The first quantum communication system 101 includes an infrared positioning system and a quantum key distribution system. The invention adopts the BB84...

Abstract

The invention discloses a wireless sensor network system based on quantum encryption. The wireless sensor network system comprises a plurality of sensor nodes and a plurality of network relay nodes; each of the sensor nodes includes a first quantum communication system, a first encryption and decryption system, a first wireless communication system, and a first data collection and processing system; each of the network relay nodes includes a second quantum communication system, a second wireless communication system, a second encryption and decryption system, a second data storage and forwarding system, and a key management system. The sensor nodes apply for keys from the network relay nodes in a neighboring area, and quantum communication channels can be established therebetween; for the network relay nodes that are not within the neighboring area, the quantum communication channels cannot be established between the sensor nodes and the network relay nodes; the sensor nodes forward a ciphertext to a target node via the network relay nodes; and the whole sensor network negotiates the keys via the quantum channels, and transmits a stream cipher via wireless communication channels. According to the system disclosed by the invention, the data transmission of the constructed wireless sensor network is secure and reliable.

Description

technical field [0001] The invention belongs to the field of quantum communication, in particular to a wireless sensor network system based on quantum encryption. Background technique [0002] Wireless sensor network is an information acquisition and processing technology, which is a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner. Its purpose is to cooperatively perceive, collect, process and monitor information of sensing objects in a geographical area covered by a sensor network and report to users. The wireless sensor network is composed of a large number of wireless sensor nodes distributed in the monitoring area, sink nodes with receiving and transmitting functions, Internet or communication satellites and task management nodes. Because wireless sensor network technology has the characteristics of wide coverage area, high monitoring accuracy, low power consumption, distribution and self-organization...
