Abstract

The invention provides an object storage metadata encryption method and system, a terminal and a storage medium. The object storage metadata encryption method comprises the steps of collecting an encryption key of a storage object and calculating a characteristic value of the encryption key; collecting attribute metadata of the storage object; converting the attribute metadata into a character string based on the encryption key feature value; and storing the character string and the encryption key characteristic value and emptying the attribute metadata. According to the invention, the metadata of the storage object can be encrypted; the metadata of the storage object can be kept in a ciphertext state all the time; in addition, feature value verification is added to ensure the consistencyof the data, so that the situation that a plurality of metadata entries need to be encrypted respectively and then an encryption program needs to be executed for multiple times originally is reduced to the situation that the metadata is only encrypted once, and the encryption time delay is reduced.

Description

technical field [0001] The present invention relates to the technical field of object storage, in particular to an object storage metadata encryption method, system, terminal and storage medium. Background technique [0002] At present, because distributed storage is becoming more and more popular, there are many related demands. Storage through object gateways is one of the three giants in distributed storage. Object storage means that the user's files are stored on the underlying disk through the object gateway. In the Linux system, in addition to the original content of the file, a file also has attribute information of the file, such as the read permission and creation time of the file, etc. etc., different from the space occupied by the file itself, the attribute information of the file exists in an independent space supported by the file system xfs of linux. The attribute information of the file is called the extended attribute of the file, which is composed of key-v...
