Device and method for exporting security information

Abstract

The invention provides a device and a method for exporting security information, the device comprises a signature verification device, the signature verification device is connected with an intranet desensitization information sending server and an extranet desensitization information receiving server, the intranet desensitization information sending server is arranged in an intranet, and the extranet desensitization information receiving server is arranged in an extranet; the signature verification device comprises an FPGA. The FPAG is connected with an intranet communication interface, an extranet communication interface, an administrator KEY interface and an algorithm chip. The intranet communication interface is connected with the intranet desensitization information sending server, and the extranet communication interface is connected with the extranet desensitization information receiving server. According to the device, the functions of the signature verification equipment are realized by using the FPGA, the signature verification equipment is ensured not to be attacked and hijacked by a hacker, the consistency of the desensitized information signed by the desensitized information approval node and the desensitized information exported to the extranet system can be effectively ensured, and the office efficiency is improved and the office cost is saved by adopting electronic management.

Description

Technical field [0001] The invention belongs to the field of network security, and specifically relates to a device and a method for realizing safety information derivation. Background technique [0002] At present, the computer office network system of many units is divided into two sets, namely the internal network system and the external network system. The intranet system is used to process sensitive information within the unit. The external network system is used for external communication. Sensitive information inside the unit needs to be kept confidential and is not expected to be learned by the outside world. Therefore, the internal network system and the external network system are isolated and cannot be interconnected. But when sensitive information has been desensitized and needs to be released to the outside world, the desensitization information of the internal network system needs to be exported to the external network system. [0003] In order to prevent the leaka...

Problems solved by technology

[0005] The purpose of the present invention is to address the above-mentioned existing intranet sensitive information management methods that are basically paper-based management, with cumbersome processes and high management costs, and because the approver cannot monitor the information burned into the CD, it will cause the approval information to be different from the burned information. In the case of information inconsistency, there is a risk of leakage of sensitive information, and a device and method for exporting security information are provided to solve the above technical problems
