Device and method for exporting security information

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.
