Abstract
A data encryption method performed at a computing device includes: receiving a data encryption request, the data encryption request indicating original data that needs to be encrypted and at least two target storage devices that are communicatively connected to the computing device; in response to the data encryption request: separately obtaining unique device information of the at least two target storage devices; generating, based on the unique device information, a public key according to a preset policy; encrypting the original data by using the public key to obtain ciphertext; and destructing relevant data of the public key from the computing device, and storing the ciphertext into the at least two target storage devices.
