An embedded information security platform

Abstract

The embedded information safety platform features the CPU micro controller as one network processing chip with ARM940T kernel containing real-time embedded operation system; enciphering and deciphering hardware chip comprising IPSec algorithm chip and symmetric algorithm chip; I / O interface including two 10 / 100 M adaptive Ethernet interfaces, one USB main control interface and one serial interface. The present invention is one opening hardware safety platform enclosed inside one casing and with relaxed application environment, powerful attack resistance and high reliability. The present invention has several enciphered algorithms, supports several kinds of application service, has high versatility, and may be used also in ciphering server, VPN ciphering gateway, SSL safety gateway, safety router, hardware fire wall and other safety devices.

Description

technical field [0001] The invention relates to a hardware device in the security field mainly used for information security transmission in a network, and belongs to the technical field of communication. Background technique [0002] At present, domestic network security hardware equipment is far behind the market demand in terms of function, performance and technology. Although the performance indicators of foreign equipment are relatively high, due to security restrictions and other reasons, even security products imported from abroad have technical problems. There are many deficiencies, so it is imminent to develop safety products with independent intellectual property rights in our country. At present, domestic network security hardware products have a single variety, low versatility, and are expensive. The current hardware encryption equipment is basically a structure of industrial computer + network card + PCI encryption card, and then applied in different packaging ...

AI Technical Summary

Problems solved by technology

Due to the high performance of the CPU, this kind of equipment can achieve high encryption and decryption efficiency, but at the same time, the hardware cost of this kind of equipment is also high, which is not conducive to the promotion of low-end users. In fact, the wide promotion of information security products is very large. To a certain extent, it depends on the popularity and use of low-end users

In addition, this form of using the PCI encryption card as a security module has very large restrictions on the host environment, such as must have an open PCI slot, and it is necessary to make different driver functions for various operating systems. The scalability is not high, so it limits the application of the PCI card encryption module to a large extent
