Abstract

The invention belongs to the data secure communication technical field and relates to a data secure communication method. The data secure communication method includes the following steps that: 1) a control center performs security authentication on interaction terminals and establishes secure communication channels; and 2) the control center allows interaction terminals which pass the security verification to perform data operation on an interaction medium through the safe communication channels, and prevents interaction terminals which do not pass the security verification from performing data operation on the interaction medium. With the data safe communication method of the invention adopted, the secure communication channels can be established more fast, and cracking difficulty of digital certificates can be increased, and the safety and reliability of a data communication process can be enhanced, and the consumption of resources of a communications system by the communication process can be reduced.

Description

technical field

[0001] The invention relates to the technical field of data communication, in particular to a data security communication method. Background technique

[0002] Nowadays, with the development of the information age, the security of information interaction has attracted more and more attention. At present, some encryption measures are adopted in various data exchanges, mainly using some digital encryption methods.

[0003] A digital certificate is a kind of electronic identity proof. Usually, a digital certificate is an invariable encrypted data. The passwords, passwords and digital certificates we use seldom use plaintext data for security. They all use encrypted data. Encrypted data It is to use a program to set an encryption protocol, that is, to ensure the consistency of encryption and decryption through a certain algorithm to facilitate verification

[0004] A very common secure communication channel establishment and data protection method is to use the...

Embodiment Construction

[0042] see figure 1 , the data security communication method of the present embodiment, comprises the following steps:

[0043] A data security communication method, comprising the steps of:

[0044] 1) The control center performs security verification on the interactive terminal and establishes a secure communication channel; specifically includes the following steps:

[0045]101) The interactive terminal queries the cached session connection information with the control center, uses the digest algorithm cached in the session connection information to perform digest calculation on the session key, and writes the session number and the digest calculation result into the connection application packet;

[0046] 102) The interactive terminal queries the cached control center certificate, and writes the serial number of the control center certificate and the serial number of the interactive terminal certificate into the connection application packet;

[0047] 103) The interactiv...
