Abstract:
1. A machine readable storage medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform operations for controlling access to a data storage device, the operations comprising: operations for providing a password prompt to a user; operations for receiving a character sequence from the user, the character sequence comprising a plurality of passwords received in response to a single password prompt, the plurality of passwords comprising delimiters that separate each password within said plurality of passwords, wherein the number of passwords prompted is different than the number of passwords required to gain access to the data storage device and wherein each password is configured to open a corresponding gate to gain access to the data storage device, wherein a set of gates that gate access to a databus are included in said data storage device; and wherein a storage access module opens a first databus gate corresponding to a first password without notifying an accessing party that the first password is correct; and operations for communicating a symbol stream corresponding to the character sequence to a password-protected data storage device wherein at least one selected symbol within the symbol stream is transmitted within a specified timing window.
