Abstract: An encryption method includes: receiving cipher data which is binary data; determining target components in a resistive memory array according to values of respective bits in the cipher data; determining current values generated by respective columns of components according to the target components; and generating key data according to the current values generated by the respective columns of components. The present disclosure can effectively reduce computing power and power consumption of an encryption process in an edge device.
