Abstract: Disclosed is a method of operating a storage device which communicates with a host device. The method includes allocating a secure region and a user region, storing first data encrypted by using a first encryption key in a first data block of the secure region, receiving a first request indicating a first secure delete operation of the first data from the host device, decrypting at least one valid data of the first data block by using the first encryption key based on the first request, wherein the at least one valid data do not include the first data, encrypting the decrypted at least one valid data by using a second encryption key different from the first encryption key, storing the encrypted at least one valid data in a second data block of the secure region, and deleting the first encryption key.

Abstract: A memory controller and a storage device including the same are disclosed. A memory controller for controlling a nonvolatile memory includes: a security access control module configured to convert biometric authentication data received from a biometric module into security configuration data having a data format according to a security standard protocol and perform, based on the security configuration data, at least one of authority registration and authority authentication of a user authority set for an access control of a secure area of the nonvolatile memory, encrypted user data being stored in the secure area; and a data processing unit configured to, based on an access to the secure area being permitted, encrypt user data received from a host device or decrypt the encrypted user data read from the secure area.

Abstract: In a method of operating a storage device including a plurality of storage regions, a first request is received. The first request is for a cryptographic erasure with respect to a first storage region. During a first time interval, a first encryption key corresponding to the first storage region is changed based on the first request. A second request is received. In response to receiving the second request within the first time interval, a region access signal is outputted. In response to determining, based on the region access signal, that the second request is associated with the first storage region, an execution of the second request is held. In response to determining, based on the region access signal, that the second request is associated with a second storage region among the plurality of storage regions, the second request is executed.
