Problems solved by technology

[0003] At present, the method of information encryption is often used to improve the security level of data, but because the key is too short, it will affect the encryption strength, and if it is too long, it will affect the encryption speed, and the encryption of a large amount of data will also increase the network burden and prolong the existing wireless communication system. The transmission time affects the transmission quality, therefore, in order to solve the current problem, it is necessary to develop a new information security technology

Abstract

The invention discloses a wireless communication encryption and decryption method, a data transmission method and a wireless communication system. The encryption method comprises the steps: carrying out the encryption authentication of a decryption party when the encryption method aims at a transmission request initiated by the decryption party; after the encryption authentication is completed, performing chaotic compression encryption on the to-be-transmitted original data to generate encrypted data; and encoding the encrypted data to obtain transmission data, and sending the transmission data to a decrypting party subjected to encryption authentication. The decryption method comprises the following steps: initiating a transmission request to an encryption party, and performing encryptionauthentication on the encryption party; after the encryption authentication is completed, performing packet loss detection and code screening on the received transmission data to obtain encrypted data; and performing chaotic decompression and decryption on the encrypted data to obtain original data. According to the encryption method, encryption of the transmission data is achieved, decryption ofthe transmission data is achieved through the decryption method, and safe data transmission is achieved between the encryption party and the decryption party.

Description
