I. Requirements Analysis

The rapid advancement of quantum computing poses a serious threat to existing cryptographic technologies. Guided by the strategic requirements of the global energy internet, the power industry adheres to the principles of "security zoning, dedicated networks, horizontal isolation, and vertical authentication." It has issued the "Notice on Matters Decided for Research and Application of Quantum Communication Technology," committing to explore the application of quantum communication technology to achieve technological upgrades and ensure network information security.

With the advancement of information technology, particularly the widespread adoption and application of the internet, networks are progressively transforming the way humans live and work. While network informatization brings convenience, it also introduces the risk of information leaks. Should a cyberattack result in data theft, enterprises and organizations will suffer significant losses.

II. Working Principle

The Quantum Cloud Control System is a suite of products supporting quantum key encryption for transmission and storage. It primarily enables quantum key generation, management, distribution, encrypted storage, and device access authentication and management. Suitable for enterprises and financial information systems, it provides a more secure solution for encrypted data transmission and storage.

III. Features and Functions

1. Quantum key source with excellent key randomness and high generation rate;

2. Supports cluster and distributed deployment;

3. Support flexible online and offline deployment of devices and key provisioning;

4. Supports domestic SM2/SM3/SM4 algorithms and international RSA/SHA256/AES algorithms;

5. Clear separation of responsibilities between administrators and operators, with straightforward operation.

IV. Typical Applications

1. Power Dispatch Command Security Management

① Quantum-Secure Command Channel: Establishes quantum-secure tunnels between the five-tier dispatch system (National Dispatch - Network Dispatch - Provincial Dispatch - Regional Dispatch - County Dispatch), enabling dynamic encryption with unique keys per command. This reduces the error rate from the conventional 1e-6 to 1e-18.

② Provides quantum-level protection for SCADA system "four remote" (remote measurement, remote signaling, remote control, remote adjustment) data, preventing command hijacking and data tampering;

③ Intelligent Scheduling Optimization Decisions: Quantum computing accelerates flow calculations, solving challenges in power grid planning and operational optimization with computational efficiency improvements exceeding 50 times.

2. Security Assurance for Intelligent Operation and Maintenance of Substations

① Quantum Protection for On-Site Automation Systems: Provides quantum encryption for IEC 61850 protocol communications to prevent tampering with control commands in smart substations;

② Enhanced Mobile Inspection Security: Prior to drone inspections, quantum keys are retrieved from the quantum cloud control system to ensure secure transmission of inspection data. Quantum-encrypted channels are provided for mobile devices such as quadruped robots and smart cameras, establishing an integrated air-ground security monitoring network.

3. Security Upgrade for Distribution Network Automation

① "Quantum + 5G" Distribution Network Protection: Deploy quantum CPE encryption devices for distribution terminals such as FTUs, DTUs, and TTUs. Establish secure channels via the 5G public network, reducing construction costs by 70%.

② Intelligent Distributed FA Protection: The Quantum Cloud Control System provides unified key management and device authentication for distributed FA, preventing "fake switch" attacks.

4. Grid Integration Safety and Optimization for New Energy: Secure Aggregation of Distributed Energy Resources

① Innovative two-stage quantum encryption with aggregation and access: First, dispersed renewable energy data is aggregated via wireless quantum encryption at regional control stations, then transmitted to the dispatch system through fiber-optic quantum encryption.

② Provide quantum protection for AGC/AVC commands in wind farms and photovoltaic power stations, preventing tampering with generation data and "pseudo-grid connection" attacks.
