Abstract: Under the “Three Types and Two Grids” strategy of State Grid Corporation, the development of integrated energy business is an important pillar of the future new energy industry. The development of integrated energy business is also inseparable from the support of information security. As a brand-new data encryption method, quantum secure communication technology has a higher level of security than traditional encryption methods. In this regard, based on the indivisible, unmeasurable, and non-reproducible technical characteristics of quantum secure communication technology, this article combines quantum secure communication technology with integrated energy business to design a solution to improve the data security of integrated energy business, and through field deployment and functional performance testing, it is verified that quantum secure communication technology can effectively improve the security of integrated energy business data.

Key words: quantum secure communication, integrated energy business, quantum key distribution, system testing
