Design requirements for security secrecy systems

According to the requirements of the system, when the network servers distributed in each province and project construction unit are interconnected through Internet, the security design of each Internet node must satisfy the general Internet Security application, and can realize the secure interconnection between the network servers. Its design requirements are as follows:

1, Security Unit Extranet and Internet interface network should first be able to ensure the basic interface security, can effectively prevent the Internet hackers illegal intrusion, to prevent network violations. Comply with the national management requirements for Internet security applications.

2, the confidentiality of the national authorities identified by the high complexity encryption algorithm, the network server to encrypt the connection to protect, to prevent third parties to steal communications information, to achieve the confidentiality of communications.

3, the integrity of the transmission of information using one-way function algorithm and digital signature for protection and verification, to prevent the Internet in transit was tampered with to ensure the integrity of the communication data.
