    摘要: According to an embodiment, a storage device connected to an external device includes a data storage, a key storage, a random number generating unit, a random number storage, a random number transmitting unit, a data receiving unit, a calculating unit, a determining unit, and a storage control unit. The data receiving unit receives write data to be written into the data storage and first authentication information. The key storage stores a key. The calculating unit calculates second authentication information for data generated from the write data and the random number by using the key. The determining unit determines whether the first authentication information and the second authentication information are identical. The storage control unit stores the write data into the data storage when the first authentication information and the second authentication information are determined to be identical.

    摘要: According to one embodiment, a storage device includes a data storage unit, a receiving unit, a selecting unit, and an authenticating unit. The data storage unit includes a secret area that becomes readable when authentication has been made by using reading authentication information and that becomes writable when authentication has been made by using writing authentication information. The receiving unit receives an access request that is either a write request indicating that data should be written into the secret area or a read request indicating that data should be read from the secret area. The selecting unit selects the writing authentication information if the access request is the write request and selects the reading authentication information if the access request is the read request. The authenticating unit authenticates an access to the secret area by using one of the writing authentication information and the reading authentication information that has been selected.
