Abstract
Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to the embodiments of the present disclosure, the memory system may generate a nonce based on a physical address of a target area of a memory device using a cryptographic algorithm, and request the memory device to authenticate the nonce. When the authentication for the nonce succeeds, the memory controller may set an authority to perform a read, write or erase operation on the target area. Through this operation, the memory system can prevent data leakage or damage by a user who has no access authority.
