Abstract
An electronic device is provided. A storage device includes a memory device and a memory controller. The memory device includes a write protection area. The memory controller controls the memory device to perform a read operation on the write protection area, in response to a series of requests regarding security read that are received from a host, provides read data received from the memory device to the host, and generates a device authentication code based on the read data. The memory controller performs generation of the device authentication code in parallel with provision of the read data to the host.
Claims20
A storage device, comprising:
- a memory device including a write protection area;
- and
- a memory controller configured to control the memory device to perform a read operation on the write protection area in response to a series of security read requests received from a host, provide read data obtained from the read operation to the host, and generate a device authentication code using the read data and a key shared with the host,
- wherein the memory controller generates the device authentication code while providing the read data to the host.
A method of operating a storage device, the method comprising:
- receiving, by the storage device, a first request among a series of security read requests and read information from a host;
- reading, by the storage device, data stored in a write protection area based on the read information;
- providing, by the storage device, the read data to the host;
- and
- generating, by the storage device, a device authentication code using the read data and a key shared with the host while
- the read data is provided to the host.
A computing system, comprising:
- a host;
- and
- a storage device, including a write protection area, configured to receive a first request among a series of security read requests with read information from the host, read target data stored in the write protection area using the read information, and provide the target data to the host while generating a device authentication code using the target data and a key shared with the host.
