The invention provides a data storage method and device, equipment and a storage medium, relates to the technical field of computers, in particular to the technical field of block chains, and can be used for cloud computing and cloud services. According to the specific implementation scheme, to-be-stored target data is divided into data fragment original texts, and storage nodes are allocated to the data fragment original texts; in a trusted execution environment, according to node information of the storage nodes, the data fragment original text is encrypted to obtain a data fragment ciphertext associated with the storage nodes; and the data fragment ciphertext is stored into the storage nodes. According to the embodiment of the invention, the security of data storage can be improved. 本公开提供了数据存储方法、装置、设备和存储介质，涉及计算机技术领域，尤其涉及区块链技术领域，可用于云计算和云服务。具体实现方案为：将待存储的目标数据划分成数据分片原文，且为所述数据分片原文分配存储节点；在可信执行环境中，根据所述存储节点的节点信息，对所述数据分片原文进行加密，以得到与存储节点关联的数据分片密文；将所述数据分片密文存入所述存储节点。本公开实施例能够提高数据存储的安全性。
