A method of encrypted communication based on application layer

Abstract

The present invention relates to an encryption communication method based on the application layer, including a first client information sending encryption method, a second client information reception decryption method, a second client information reply encryption method and a first client information reception encryption method The decryption method, the encryption method for the first information transmission of the first client includes the following steps: generating the first virtual data header; generating the first user data; generating the second virtual data header, adding the first data receiving whitelist; establishing the first mapping relationship table and storing; generating the first ciphertext and sending it; generating second user data; encrypting the data body of the second user data to obtain third user data and sending it. The invention has the advantages of: ensuring that the original data header information is not leaked and can inform the other client of the virtual data header corresponding to the original data header; it can prevent hackers from intercepting the data header for data counterfeiting; it avoids the inability to determine the ciphertext due to the data header encryption The size and the issue of when to start decrypting.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to an application layer-based encrypted communication method. Background technique [0002] Since the 20th century, with the development of computer technology, network transmission technology has become an important means of information transmission in the fields of industry, agriculture and national defense, and gradually began to enter other fields of society. As the network gradually penetrates into people's life, work and entertainment, information security issues during network transmission have increasingly become a focus of attention. In order to improve the security of user information in network transmission, network transmission data encryption technology has gradually become a research hotspot. At present, the commonly used data encryption technologies include digital signature authentication, personal identity authentication, and electronic seal. Althou...

Problems solved by technology

[0004] The main existing encryption scheme of the present invention only encrypts the data body and does not encrypt the data body, causing hackers to affect the business by intercepting the data header. Encrypting the data header will solve the problem of communication services, and provide a virtual data header by setting. The encrypted communication method based on the application layer and the virtual data head will change in real time
