Abstract

The invention belongs to the field of information safety and provides a data encryption sending method, a data terminal and a server. The method comprises generating an encryption key through a preset algorithm randomly and exchanging the encryption key according to the preset frequency, sending a data sending requirement including the encryption key to a receiving end through a server, and encrypting the data to be sent according to the encryption key and sending the data to the receiving end when the data sending requirement is received at the data receiving end. By the aid of the method, the data terminal and the server, the data obtaining difficulty by the outside is improved, and the data security is protected to the largest extent.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for encrypting and sending data, a data terminal and a server. Background technique [0002] The concept of information security has gone through a long historical stage in this century and has been deepened since the 1990s. In the 21st century, with the continuous development of information technology, the issue of information security has become increasingly prominent. How to ensure the security of information systems has become a concern of the whole society. Internationally, the research on information security started earlier, with great investment, and many achievements have been made, which have been popularized and applied. China already has a number of research institutes and high-tech enterprises specialized in information security basic research, technology development and technical services, forming the embryonic form of China's information security in...
