Parameter configuration method and device based on multiple systems

The invention provides a parameter configuration method and device based on multiple systems, and relates to the technical field of big data, and the method comprises the steps: obtaining a to-be-managed parameter uploaded by a target system; the to-be-managed parameters comprise keywords; extracting a keyword, and encrypting the keyword by using an encryption machine to obtain a keyword ciphertext; encrypting the to-be-managed parameter by using a pre-generated public key to obtain a parameter information ciphertext; uploading the keyword ciphertext and the parameter information ciphertext to a cloud storage platform; based on a MapReduce model, determining a target keyword ciphertext in a cloud storage platform by utilizing the retrieval keyword ciphertext; and decrypting the parameter information ciphertext corresponding to the target keyword ciphertext by using a pre-generated private key to obtain parameter information. According to the method, the parameters can be classified, the keywords can be establ
