Wireless encryption communication method and system

Abstract

The invention discloses a wireless encryption communication method and system. The method comprises the following steps: S1, identities of an information sending end and an information receiving end are verified; S2, the information receiving end generates a public key K-Pu and a private key K-Pr of the transmission according to an asymmetric encryption algorithm, and sends the public key K-Pu tothe information sending end; S3, the information sending end generates a secret key K-A of the transmission according to a symmetric encryption algorithm, and encrypts the secret key K-A by using a public key K-Pu according to an asymmetric encryption algorithm to obtain a ciphertext M-K; S4, the information sending end randomly generates interference information W-G; and S5, the information sending end encrypts a plaintext to be sent by using a symmetric encryption algorithm to obtain a ciphertext M-M. According to the invention, the risk of using a single symmetric encryption algorithm to the system is solved, the risk of being intercepted in secret key transmission is effectively avoided, and the information transmission security of the wireless transmission device is improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a wireless encrypted communication method and system. Background technique [0002] With the continuous development of communication technology, communication equipment is widely used in various mobile terminal equipment, and the rapidity of communication transmission has buried hidden dangers for security issues. In the process of identification, connection and transmission of communication equipment, it is easy for criminals to steal data, which will endanger the security of user information. In the existing technology, the encryption level of data transmission information between two short-distance communication segments is still relatively low. [0003] Currently common encryption protection technologies between wireless communication systems include: [0004] 1. Only a single symmetric encryption algorithm such as AES is used for encryption, and when the secre...

AI Technical Summary

Problems solved by technology

[0004] 1. Only a single symmetric encryption algorithm such as AES is used for encryption, and when the secret key of the symmetric encryption algorithm is transmitted in the wireless network, it is easy to be intercepted and cracked, resulting in information leakage

[0005] 2. Only a single asymmetric encryption algorithm such as RSA is used for encryption, which improves the security, but will greatly increase the resource consumption of the system for encryption

It makes the system take longer to complete an encrypted transmission, which cannot meet the application fields with high real-time requirements

[0006] 3. No encryption algorithm is used to encrypt the information. Although the direct transparent transmission method improves the efficiency, the interception of the information leads to the leakage of the information.
