The invention discloses a method, equipment and system for using an industrial vulnerability feature library based on a national cryptographic algorithm, and belongs to the field of industrial control networks, and the method comprises the following steps: from the whole life cycle of initialization and deployment of the vulnerability feature library, decryption of all data based on the national cryptographic algorithm is completed in a memory; and no text data of any plaintext is stored. According to the scheme, the original data, the initialization process and the deployment process of the data of the vulnerability feature library all use the encrypted data, so that the risk of plaintext leakage of the data of the industrial vulnerability feature library cannot be caused no matter the operations such as later engineering implementation joint debugging or remote joint debugging, and the use security of the industrial vulnerability feature library is greatly improved. And meanwhile, a national secret algorith
