Abstract

The invention discloses a key management method and device for a distributed block storage system, and the method is applied to a client, and comprises the steps: building first block equipment according to a first building instruction carrying an encryption attribute and an encryption algorithm identification; if the encryption attribute indicates that the first block device is an encryption device, sending a first key creation request containing the encryption and decryption algorithm identifier to a server; and receiving a first key ID fed back by the server according to the first key creation request, wherein the first key ID is fed back by the server after the server confirms that the identity of the client user is legal. According to the secret key management method for the distributed block storage system, when the block device is created, for the block device with the encryption attribute being the encryption device, the secret key is automatically created, the secret key is created after the server confirms that the identity of the client is legal, and the secret key ID stored in association with the secret key is fed back, so that the safety management of the secret keyis ensured, the storage safety of the block device data is improved, and a basis is provided for the subsequent safety management of the secret key of the block device.

Description

technical field [0001] The invention relates to the technical field of cloud computing security, in particular to a key management method and device for a distributed block storage system. Background technique [0002] Facing the demand for massive data storage brought about by the continuous improvement of informatization, traditional storage systems have bottlenecks in the expansion of capacity and performance. Cloud storage has been widely recognized by the industry for its advantages such as strong scalability, high cost performance, and good fault tolerance. As an important technology in cloud storage, distributed block storage has become an important cornerstone for the development of cloud storage. In some specific cloud computing application scenarios, the distributed storage system provides block devices to the upper layer for client users to use. For example, Ceph provides block devices for use by OpenStack components. [0003] In large-scale distributed storage...
