Problems solved by technology
For security requirements, IPSec VPN is currently used to encrypt data transmission and security authentication by building a secure tunnel. Since the IPSec protocol is an application based on the IP network layer, various routing and forwarding methods provided by the IP protocol suite are still required for data transmission. , leading to the problem that QoS and security cannot be well balanced in the power network

[0060] As a complex and huge energy exchange system, the smart grid requires sufficient information exchange and sharing between nodes in the power communication network. Smart grid communication is mainly divided into two types: one is wide-area communication between "big nodes" in the power communication network, such as communication between dispatch cen...

The invention relates to an electric power communication backbone network data security protection method and system based on MPLS, an IPsec security tunnel of a network layer is constructed on an IP network layer through IKE and IPsec negotiation, an MPLS security tunnel is constructed on a link layer through authentication data and labels exchanged in an MPLS domain, double-tunnel data encryption and authentication technologies are realized, and effective guarantee is provided for data transmission security; meanwhile, the IP message transmitted by the IPSec tunnel is completely packaged in the whole MPLS domain, the data forwarding service is provided by the label switching path instead of adopting a routing path to forward data, the advantage of the MPLS on the QoS technology requirement can be exerted, and compared with a routing forwarding mode, the operation burden is low, the transmission bandwidth of the network can be greatly improved, the transmission time delay and the data packet loss rate are reduced, and the network resource utilization rate is improved; and a key value for providing security assurance by a link layer is only known at two adjacent LSRs, and meanwhile, security association parameters in an IKE SA negotiation process are introduced, so that the security of a network environment is enhanced to the greatest extent.
Description
technical field [0001] The invention relates to the application field of multi-protocol label switching technology, in particular to a data security protection method and system for constructing an MPLS VPN framework in an electric power communication backbone network. Background technique [0002] The smart grid is the intelligence of the power grid, also known as the "grid 2.0" era. It is based on an integrated, high-speed two-way communication network, through advanced sensing and measurement technology, advanced equipment technology, and advanced control methods. And the application of advanced decision support system technology to achieve the goals of reliability, safety, economy, high efficiency, environmental friendliness and safe use of the power grid. The power communication backbone network is the transmission medium of the core business of the power communication network, and plays an important supporting role in the production, operation and dispatch of power.
