“…The management service channel and business service channel between the secondary module of the main station and the real-time gateway machine (secondary) adopt the security mechanism based on the state secret SM2 authentication and certification to guarantee the security of the connection and data, and the certificate is used to interact in an offline way [10]. The MQTT load data of the management service channel is accompanied by a signature at the end of the data to guarantee the security of the data; the business service pipeline, after the establishment of the TCP (Transmission Control Protocol) connection, carries out the authentication of the channel first to guarantee the security of the connection and then carry out the business data interaction.…”

To meet the needs of the promotion of “equipment ownership” and the implementation of a centralized monitoring mode in substations, a technical scheme of unified monitoring, online operation, and maintenance for secondary equipment in substations is proposed, considering the monitoring, operation, and maintenance requirements of secondary equipment such as protection devices and automation devices. A secondary equipment monitoring real-time gateway is arranged in Security Zone I. The comprehensive operation status data of various secondary equipment is collected, analyzed, processed, diagnosed, and applied through various apps, to realize heterogeneous access, on-demand deployment, and flexible expansion. The master station is designed with functions such as human-machine interaction and remote analysis for secondary device monitoring and operation. GSP, MQTT, and other service-oriented and message mechanism communication protocols are adopted between the substation and the master station to meet the diversified and easily expandable information exchange requirements. Through the factory test, it is verified that the scheme can realize the panoramic perception of the operation state of the secondary system and effectively improve the ability of abnormality diagnosis and processing.

“…While these new power terminals improve efficiency, they also bring new security risks. Some malicious or unauthorized terminals may access cloud resources beyond their authorized permissions in an illegal manner [2,3] . By adopting an attribute-based encryption (ABE) scheme, terminals can be filtered based on their attributes, and only terminals that meet the attribute requirements can decrypt the cloud resource (e.g., IP and port) and obtain the corresponding access permissions [4] .…”

The introduction of new power terminals has improved the efficiency of the new power system, but it has also brought new risks. It is important to research ways to prevent cloud resources from unauthorized access by these terminals. To address this issue, an access control scheme was proposed based on Ciphertext-Policy Attribute-Based Encryption (CPABE) technology, which can encrypt cloud resource information and make access control fine-grained. We also combine the SM9 algorithm to reduce the key management burden of traditional CPABE technology and introduce a zero-trust mechanism to provide a higher level of security protection for the subsequent access control process of the terminal. Additionally, we prove the correctness and analysis of the attack, which can be resisted by the proposed scheme, demonstrating its feasibility and security. Finally, a comparison was made between our scheme and other CPABE schemes. Our scheme is proven to perform better in performance.

This paper presents a unified framework to analyze the performance of a complex network containing diversified link capacities with specified flow requirement in terms of Capacity Related Reliability (CRR). An efficient minimal cutset based methodology is proposed to enumerate irredundant subset cut groups (SCGs) to evaluate flow networks reliability. The proposed approach is a two-step process. The first step requires a prior knowledge of all minimal cutsets of the network along with an enumeration of all irredundant subsets of cutset group (SCG) from a cut matrix to block or allow a prescribed amount of flow. In the second step, the enumerated SCGs can be fed as input to any multi-variable inversion sum-of-disjoint-product (MVI-SDP) based reliability evaluation algorithm to obtain the CRR of the network. The versatility of the proposed approach is that a single framework can be used to evaluate all the reliability measures such as 2-terminal, k-terminal and all-terminal. Various benchmark networks available in literature have been used to analyze the performance of the proposed methodology in terms of complexity and time constraint.
