Abstract
According to one embodiment, a key management device includes a storage and a server. The storage includes a first nonvolatile memory, and a first controller configured to encrypt, using a first media encryption key, data from a host, and store the encrypted data in the first nonvolatile memory. The server includes a second nonvolatile memory storing a first key, and a second controller configured to transmit the first key from the second nonvolatile memory to the storage without passing through the host.
