Method for encryption in sensor network, encryption device and sensor network

Abstract

The invention provides a method of encryption is a sensor network. The sensor network comprises a plurality of sensor nodes, and the method comprises the steps of collecting capacity information of the sensor nodes in the sensor network, obtaining parameters of a sensor node which is currently needed according to the capacity information, searching an encryption algorithm meeting the conditions according to the parameters of the sensor node, and encrypting data collected by the sensor node through the encryption algorithm meeting the conditions. In the sensor network, the capacity information of the sensor nodes is collected, and safety parameters and energy consumption parameters of different encryption algorithms are collected. In the capacity range of the sensor nodes, an encryption scheme which is good in safety and provided with resources within the capacity range of the sensor node is selected. Safety requirements are met, and meanwhile storage, calculation and communication resources of the sensor network are saved to the maximum extent.
