Data processing method, device and system and electronic equipment

The embodiment of the invention provides a data processing method and device and electronic equipment, and the method comprises the steps that a management and control node receives a metadata requesttransmitted by an edge computing node, carries out the encryption on the metadata requested by the edge computing node, obtains encrypted metadata, and transmits the encrypted metadata to the edge computing node. According to the scheme of the embodiment of the invention, the security of the metadata can be ensured on the premise that the metadata is still stored in the edge computing node. 本发明实施例提供一种数据处理方法、装置及电子设备，其中，方法包括：管控节点接收边缘计算节点发送的元数据请求，并对边缘计算节点所请求的元数据进行加密处理得到加密元数据，将加密元数据发送至边缘计算节点。本发明实施例的方案，能够使元数据仍被存放在边缘计算节点的前提下，确保元数据的安全性。
