Research On The Secure Access System Of New Energy Plants Based On SM2 Algorithm

With the construction and network access of more and more new energy plants,the network security risk of new energy plants is increasingly prominent,especially the access risk of acquisition terminal.On the one hand,attacks from the network of new energy plant may penetrate upward,which seriously threatens the security and stability of the whole power grid dispatching control system;on the other hand,although the network of new energy plant has the necessary security protection capabilities such as firewall and isolation device,its monitoring system,control system and network information system are also likely to be affected by the vertical boundary of the network Infiltration and attack lead to unpredictable two-way security consequences.Therefore,in view of the security problems existing in the acquisition terminal of the new energy plant station,it has become an urgent problem to research and implement the corresponding security access system of the new energy plant station.In this paper,through analyzing the security problems faced by the new energy plant's acquisition terminals,and combining with the national security protection standards,from the three aspects of terminal security protection,channel security protection and station control layer security protection,the research and implementation of the new energy plant's acquisition terminal security access system,in which channel security protection is the focus of this paper and connecting other The link of two parts of safety protection.In the aspect of channel security protection,this paper deeply studies and studies the related technologies of channel security protection,including elliptic curve encryption technology,identity authentication technology based on public key infrastructure system,key exchange protocol,etc.,and designs an improved key exchange protocol based on SM2,which can reduce the communication between the two sides in information exchange under the premise of ensuring the security performance Then,we test the improved SM2 key exchange protocol,and apply this part of the design to the channel security protection of new energy plants.Finally,based on the channel security protection,after analyzing the security requirements,this paper designs and realizes the terminal security protection and station control layer security protection on both sides,and finally constructs a complete security access system suitable for the new energy plant station acquisition terminal.In order to develop the prototype of the encryption authentication device suitable for the acquisition terminal of the power generation unit of the new energy plant in the future according to the above theoretical basis and implementation scheme,and carry out the pilot application test.It not only ensures the safety protection of the collection terminal of the new energy plant,but also promotes the development of the new energy industry.
