Abstract

The invention provides a double control network encryptor system, which comprises a network encryptor A and a network encryptor B. The network encryptor A and the network encryptor B perform network encryption simultaneously, use a high-speed data bus for data synchronization, guarantee consistency of the data at any time, and are connected by a heartbeat cable. The system is erected between an external network and an internal network. The network encryptor A and the network encryptor B of the system isolate the data of the internal network and the external network, encrypt data simultaneously and synchronize in real time; and connection of the encryptors by the heartbeat cable ensures that the other network encryptor is informed of taking charge of all encryption tasks when any one network encryptor goes down, so that the encrypted data is guaranteed to be safe and reliable.

Description

A kind of dual control network encryption machine system

Technical field

The present invention relates to the network safety filed of cloud computing, be used in controlled secure network application, specifically a kind of dual control network encryption machine system.

Background technology

Common network encryption machine in application process, occur system delay machine or machine breakdown time, the situation that network cannot communicate can be caused.The scheme of a kind of network more safely and reliably secret machine is needed to address this problem.

Summary of the invention

The object of this invention is to provide a kind of dual control network encryption machine system.

The object of the invention is to realize in the following manner, system comprises network encryption machine A and network encryption machine B, and two encryption equipment functions are consistent, and network encryption machine A and network encryption machine B is connected to outer net and Intranet, wherein:

1) network encryption machine A and network encryption machine B can by outer network data and intranet data completely isolated, the enciphered data of outer net is dealt into Intranet by encryption, and the data of Intranet are sent to outer net by encryption;

2) network encryption machine A is connected by high speed data bus with network encryption machine B, the data that real-time synchronization is mutual and encryption and decryption task;

3) have heartbeat to be connected between network encryption machine A and network encryption machine B, guarantee system network encryption machine delay machine time, data transmit and cryptographic tasks by another encryption equipment take over, guarantee data safety.

The invention has the beneficial effects as follows: the network encryption machine A of native system and network encryption machine B isolates intranet and extranet data, network encryption machine A and network encryption machine B works simultaneously, enciphered data real-time synchronization, heartbeat be connected ensure any network encryption machine delay machine time notify another adapter all cryptographic tasks, ensure enciphered data safe and reliable.

Accompanying drawing explanation

Fig. 1 is dual control network encryption machine system configuration schematic diagram.
