Data protection method and device for target cloud equipment and storage medium

The embodiment of the invention discloses a data protection method and device for target cloud equipment and a storage medium, and related embodiments can be applied to various scenes such as cloud technology or artificial intelligence, and are used for protecting data security of the target cloud equipment and preventing data leakage. The method comprises the steps that a data reading request sent by a first terminal device is received, a first secret key is acquired according to information of a first object carried in the data reading request, and the first secret key is generated based on the information of the first object, a target device identifier and target time information; the target time information is time when the first terminal device applies for a secret key, reading target ciphertext data from a first storage space included in the target cloud device according to a target device identifier carried in the data reading request, decrypting the target ciphertext data through the first secret key
