Abstract
A first storage device provides a host device with access to a private memory area by communicating a password between the first storage device and a second storage device via the host device using a double-encryption scheme. In one embodiment, a host device receives a twice-encrypted password from a first storage device, sends the twice-encrypted password to a second storage device, receives a once-encrypted password from the second storage device, decrypts the once-encrypted password to obtain the password, and sends the password to the first storage device. In another embodiment, a first storage device sends a twice-encrypted password to a host device, receives the password from the host device after the twice-encrypted password is decrypted by a second storage device and the host device, and provides the host device with access to the private memory area only if the password matches one that is stored in the first storage device.
