Claims7
A computing system comprising:
- a storage device that includes a memory device including a write protection area;
- and
- a host configured to perform an operation of providing, to the storage device, a first request regarding security write and write data in parallel with an operation of generating a host authentication code based on the write data and a key shared with the storage device.
A storage device comprising:
- a memory device including a write protection area;
- and
- a memory controller configured to:
- receive a first request and read information regarding a security read from a host;
- control the memory device to perform a read operation on the write protection area based on the first request and the read information;
- generate a device authentication code based on a key shared with the host and read data associated with the read operation, in parallel with transmitting a first response including the read data to the host and;
- receive a second request from the host;
- and
- provide, to the host, the device authentication code in response to the second request.
