Phone Number Scramble
Callers with a good understanding of how to get through to an unfamiliar number can “scramble” a number to make it difficult for an automated telephone service to connect with that number. The process is a bit more complex, but essentially, when an automated telephone system attempts to connect with the number, the user can simply press any key to try and guess the number being dialed, and if the caller’s guess is incorrect, then the system will disconnect.
Here’s a little more about how it works:
When the user tries to connect with an unfamiliar number, the automated phone system responds by sending a message through the phone system that says, “This number is being forwarded to a number already in use.” This message contains the number being dialed and a four-digit number that matches the number being forwarded.
So, if the user dials “202.10.1014” and the system thinks it’s “204.10.1014”, the system will send a message through the phone system to the system that the “10” is a phone number already being used by another subscriber, and the system will switch the call back to the previous dialed number (202.10.1014). As we saw earlier in the book, the system doesn’t really know how to tell if a person has the number. Because if the caller thinks the number is “202.10.1014”, then it has to be 202.10.1014, and they’re still on the phone. The number “202.10.1014” is already in use as “204.10.1014”, and the system just assumes it’s “202.10.1014” because it doesn’t know otherwise.
The most famous example of this type of error is that of the person that left a message on the president’s phone. The message was “Do not call me again.” This message was sent over the Air Force one-way system, so no one received it. A year later, there was a big protest over the administration’s decision to include this message in the record of that person’s phone call.
What’s most important here, is that “202.10.1014” is not known in advance to any person in the system. It could be “188.8.131.52” (for “White House”), or it could be “184.108.40.206” (for “National Security”). In this case, “202.10.1014” would be the correct message for Air Force One.
The Air Force One System
The first step in the Air Force One system is to identify the presidential aircraft. All of the major aircraft in the air force are required to be identified to the Air Force, which can then have it sent to the White House. The president receives the information via a secure channel between the Air Force and the White House, such as the Secure Call System (SCCS). The Air Force then contacts the proper aircraft. The aircraft then identifies the Air Force One aircraft, and the president and vice president each receives a new “ticket” which has a different identification number for each aircraft. The two numbers are used to identify each flight from the Air Force One computer system. A user called a “handler” is assigned the responsibility of making the identification. Air Force One is capable
