Encrypted communication method based on application layer

Abstract

The invention relates to an encrypted communication method based on an application layer. The method comprises a first client first information sending encryption method, a second client first information receiving decryption method, a second client information reply encryption method and a first client first information receiving decryption method. The first client first information sending encryption method comprises the following steps: generating a first virtual data head; generating first user data; generating a second virtual data head, and adding the second virtual data head into the first data receiving white list; establishing and storing a first mapping relation table; generating and sending a first ciphertext; generating second user data; and encrypting the data volume of the second user data to obtain third user data, and sending the third user data. The method has the advantages that it is guaranteed that original data head information is not leaked, and an opposite clientcan be informed of the virtual data head corresponding to the original data head; a hacker can be prevented from intercepting a data head to counterfeit data; the problem that the ciphertext size andwhen to start decryption cannot be determined due to data head encryption is avoided.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to an encryption communication method based on an application layer. 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, the information security problem in the network transmission process has increasingly become a hot spot that everyone pays attention to. 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 aut...

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
