Secure Transmission Method of Wireless Network Communication Data Based on Symmetric Key Encryption Algorithm
In order to improve the stability and security of data transmission,this paper proposes a secure transmission method of wireless network communication data based on symmetric key encryption algorithm.Based on the detailed data security transmission protocol,the symmetric key encryption algorithm is used to construct the key,and the key distribution mechanism is adopted to ensure that all nodes hold effective and consistent keys.Then,a data transmission model is established to improve the efficiency of data transmission through a reasonable hierarchical structure.Finally,in the back-end data unloading stage,encryption processing is realized to ensure that the data is not illegally accessed or tampered with during transmission.Experiments show that the transmission stability of this method is close to 99.8%,and the transmission effect is good.
