Abstract
A data storage device is secured by extracting timing information encoded within a password-related symbol stream received by the storage device and denying access if the timing information is incorrect or the symbol stream is not identical to a valid authentication sequence. In one embodiment, each symbol corresponds to a password, and at least one symbol is transmitted within a specified timing window while at least one other symbol must be transmitted at a random time that varies with each authentication attempt. In certain embodiments, a computing device associated with the data storage device is configured to provide a single password prompt, receive a character sequence corresponding to a plurality of passwords from a user, and communicate an encrypted symbol stream to the storage device with a specified timing pattern imposed thereon.
