One-time cipher based back door program for executing emergency commands. Secure Back Door(SBD) is an alternative to leaving SSH open all the time. It is based on a secure one-time keypad method, that insures maximum security. Since SBD is very small, it is less likely to have security exploits, as compared to SSH. Therefore, you could leave an important computer up and running with just sbdd running in the background, and if an emergency came about, you could simple execute a command to bring ssh up, then work on the computer as regular. It would be as simple as doing ./sbd domain.com "/etc/init.d/sshd start", and with the proper key file set, the remote computer would have ssh up and running shortly.
