Secret-related information maintenance method and device, equipment and storage medium

The invention discloses a secret-related information maintenance method and device, equipment and a storage medium, relates to the technical field of data security, is applied to a TEE server, and comprises the following steps: generating a public and private key pair based on a key management system and a preset encryption algorithm, and uploading a public key in the public and private key pair to a certificate authentication mechanism for storage; through a preset key negotiation algorithm, negotiating a corresponding session key based on the public key and the user front end; receiving encrypted data sent by the user front end; the encrypted data is ciphertext data obtained by encrypting secret-related data by the user front end by using a session key; and decrypting the encrypted data by using the session key to obtain corresponding decrypted data. According to the method and the device, a safe computing environment is provided, so that the sensitive information can be safely computed and processed in the
