System and method for protecting disk drive password when BIOS causes computer to leave suspend state |
摘要 |
To unlock a HDD when a computer is in the suspend state, at both BIOS and the HDD a secret is combined with a password to render a new one-time password. BIOS sends its new one-time password to the HDD which unlocks itself only if a match is found. The new one-time password is then saved as an “old” password for subsequent combination with the secret when coming out of subsequent suspend states. In this way, if a computer is stolen the thief cannot sniff the bus between BIOS and the HDD to obtain a password that is of any use once the computer ever re-enters the suspend state.
