摘要
针对簇-树型的数据传输精确性提出一种算法.该算法是节点通过从基站接收到的话路密钥Kb与节点出厂时就设置的密钥Ki对感知数据进行加密,数据加密后使用密钥公式传送数据,可以进一步增强数据的精确性和完整性.
This paper we proposed a cluster-tree algorithm in order to improve data accuracy due to still exist the non-relia- bility in data transmission. Sensor nodes receive the session key Kb from the base station, encrypt the date with a node specific secret key Ki and the session key Kb. Through using data encryption format to transmit data after encrypting the data, this algorithm can further enhance the accuracy and completeness of data.
