Memory system, memory controller and operation method thereof for encrypting data stored in a nonvolatile memory

Abstract

The present disclosure relates to a memory system capable of encrypting and storing data, and a memory controller. The memory controller may include a first interface configured to perform data communication with a first external device, a second interface configured to generate a signal for controlling an operation of a second external device and transmit the signal; and a processor configured to receive, from the first external device, a data write command to write data to the second external device, encrypt the data by using one of a plurality of keys stored in a key area provided in the first external device in response to the data write command, and then control the encrypted data to be written to the second external device.

Dependencies are inferred from the claim text.
