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

Embodiment

[0045] This embodiment is a client-side encrypted communication method, which is used for mutual communication between a first client and a second client, including an encryption method for the first client to send information, a second client to receive and decrypt the first information, and a second The client-side information reply encryption method and the first client's first-time information reception and decryption method, the first client's first-time information transmission encryption method includes the following: figure 1 shown, the following steps:

[0046] S01: generate a first virtual data header, the virtual data header includes a version number, a data length and a data type, the data length is the length of the data body that forms user data with the virtual data header, and the version number and the data type are according to preset The rules are changed, and the same rules are stored in the first client and the second client, that is, after the first virtu...

Abstract

The invention relates to a client encrypted communication method, including an encryption method for the first information transmission of a first client, a decryption method for the first information reception of a second client, a reply encryption method for the second client information and a method for the first information reception and decryption of the first client , the method for encrypting the first information sent by the first client includes the following steps: generating a first virtual data header; generating first user data; generating a second virtual data header, adding the first data receiving white list; establishing a first mapping relationship table and storing ; generate the first ciphertext and send it; generate the second user data; encrypt the data body of the second user data to obtain the third user data and send it. The invention has the advantages of: ensuring that the original data header information is not leaked and can inform the opposite client of the virtual data header corresponding to the original data header; preventing hackers from intercepting the data header for data counterfeiting; avoiding the inability to determine the ciphertext due to the encryption of the data header size and when to start decryption.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a client 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. Although we have been ab...
