IPSec (Internet Protocol Security) protocol outgoing processing hardware implementation system under IPv6 (Internet Protocol version 6)

Abstract

The invention provides an IPSec (Internet Protocol Security) protocol outgoing processing hardware implementation system under an IPv6 (Internet Protocol version 6). The IPSec protocol outgoing processing hardware implementation system comprises an internal network GMAC module, a data-in cache module, an IPSec protocol encapsulation processing module, an SA matching module, an encryption module, an authentication module, a message fragmentation module, a data-out cache module and an external network GMAC module. According to the IPSec protocol outgoing processing hardware implementation system under the IPv6, the IPSec protocol outgoing processing on the network layer IP (Internet Protocol) datagram under the IPv6 environment is implemented through hardware and accordingly the IP datagram source point identification and the data integrity and confidentiality are achieved, the software based IPSec protocol outgoing processing speed is effectively improved, and a CPU (Central Processing Unit) can be completely released out in the processing process.

Description

technical field [0001] The invention relates to the technical field of network security data processing, in particular to an IPSec protocol outbound processing hardware implementation system under IPv6. Background technique [0002] With the rapid development of the Internet, people rely more and more on it, and network information can be delivered cheaply and quickly. Therefore, in such an information age, the security of network information has become the focus of people's attention. This not only involves people's personal privacy and property information, but also concerns the confidential information of various companies. The most important thing is that it concerns a National sovereignty, security and development. "Information warfare" has become an important means in modern warfare. Therefore, network information security has become an area that must be guaranteed by countries, departments and industries. At present, the Internet is based on the IP protocol (Interne...

AI Technical Summary

Problems solved by technology

The IPSec protocol involves the secure calculation of a large amount of data. With the continuous improvement of computer network bandwidth, the use of software to implement IPSec protocol processing takes up a lot of CPU resources, which significantly increases the load of network equipment and significantly reduces throughput, resulting in servers, gateways, routers and The processing performance of key network equipment such as switches is greatly reduced

Moreover, in the new version of IPv6 environment with a larger address space, the amount of data to be processed is even greater
