The invention provides a data storage method and device, electronic equipment and a computer readable storage medium, and relates to the technical field of terminals.At least two trusted execution environment (TEE) systems are arranged on the electronic equipment, and when a client application CA in a rich execution environment (REE) system needs to store data in a storage medium of the TEE systems, the TEE systems can store the data in the storage medium of the TEE systems. According to the embodiment of the invention, the data are respectively stored in the storage media of the plurality of TEE systems, and the risk that the plurality of TEE systems are attacked is low, so that the data in at least one TEE system can be ensured to be correct, and the accuracy of the data is ensured. And when the CA needs to use the data in the TEE system to carry out related service operation, correct data can be obtained from at least one TEE system, so that the accuracy of the service operation can ...
