Data query method and device, storage medium and electronic equipment

The invention provides a data query method and device, a storage medium and electronic device.The method is applied to an agent party and comprises the steps that a to-be-queried ciphertext set related to a to-be-queried keyword and sent by a query party is received, the to-be-queried ciphertext set is obtained by encrypting a to-be-queried data set through a symmetric key by the query party, and the to-be-queried keyword is stored in the to-be-queried data set; the to-be-queried data set comprises a hash result of the to-be-queried keyword; receiving a query data ciphertext set sent by a data source party; obtaining a target ciphertext set according to the to-be-queried ciphertext set and the query data ciphertext set; and sending the ciphertext set to the query party, so that the query party decrypts and matches the ciphertext set to obtain a query result of the to-be-queried keyword. The data transmission time delay can be reduced, and the data query efficiency can be improved. 本申请提供了一种数据查询的方法、装置、存储介质及电子设备
