‘Shuttle Tydirium, what is your cargo and destination?’


VADER: Where is that shuttle going?

PIETT: Shuttle Tydirium, what is your cargo and destination?

PILOT VOICE: Parts and technical crew for the forest moon.

VADER: Do they have a code clearance?

PIETT: It’s an older code, sir, but it checks out. I was about to clear them.


In modern cryptography, a system is designed so that it is difficult to break. The only part that must be kept secret are the keys used to encrypt the message. Changing Keys is necessary from time to time because an attacker who learns the key can easily break any message that is encrypted.

If  the rebels steal  their keys, re-entry of periodic information ensures that the problem is limited in time.

In a military situation where your opponent will go far to steal the keys, there is a logistics problem of how to distribute new keys. You can not send on a channel that is set by the old keys. You must use a separate system (and how to ensure that these keys are safe?) Or by mail. But when their units are scattered throughout the planet or galaxy, one can not have a daily courier service. You should also plan your mail service to fail, either because the mail is intercepted, or the rendezvous point is not available. So you have to send a set of keys to be used in the next N cycles.

In World War II, the Allies took advantage of it, attacking the Nazis weather ships. (The plan may come from Ian Fleming, who went on to write novels of James Bond.) For the capture key, the Allies were able to read the Nazi traffic.

In any case, Piett was about to authorize the landing of the shuttle. The history of cryptography is full of examples that happened not too long ago, but the pattern is the same. The desire to believe that all is well, the pressure of the routine, and the belief that the operator that the little abnormal is pretty close to normal combine to justify bending the rules a bit.

Piett is about to accept a key release date, a decision that is militarily and psychologically cryptographically probably take sensible. The process design means that such anomalies are expected. This is why the expectation is heroic effort worth stealing keys. (Such efforts are the reasons behind the work of Jack Shaftoe in Stephenson “the Cryptonomicon.”) Even with systems designed in accordance with the principle of Kerkhoff, key management is a difficult challenge.

Also, be sure to check out the gallery Piett, whose image today, asked me borrow. On Friday, we can make a detour to Tatooine to answer a question reader, or I can start in the classic Saltzer and Schroeder. I’m always looking for a good web version that I can link. Finally, thanks to DM noticed some flaws in the first draft.

How did the Rebels steal the Imperial shuttle Tydirium?

A lot of large discrepancies in the EU were the result of the clear dividing line between the old stuff that came during and immediately after the original trilogy, in which the continuity has been less than a serious concern, and “modern” EU began with Tim Zahn in the nineties. Theft Tydirium, however, probably because of its location in Return of the Jedi, and then, towards the end of most of the first EU-was not even mentioned until 1994, and was later re-counted two sometimes the next ten years or so.

How the Rebels Stole the Tydirium

That first version of the story, ironically, is undoubtedly the most vulgar and mediocre. To hear him tell the story, the young driver rebel known only as starter was nothing less than an army of one man; fighting alone against a large group of bounty hunters (for which we were hunting? who knows) including IG-88, Dengar, and Zuckuss before being taken prisoner by none other than the own Boba Fett and handed over to Darth Vader, I quickly locked in his room of meditation, then the flight in an imperial shuttle is put back to the Alliance.

While this is, of course, the stupidest of history, for once, the author, Peter Schweighofer, find the joke, and apparently intended to be nothing more than a story of a braggart, which means the true story It would still be counted for another five years. On the flight simulation game X-Wing Alliance, one of my favorite things, play another young pilot named Ace Azzameen, whose shipping family is involved unwillingly in the Galactic Civil War as a result of the Battle of Hoth.

Most of the game is spent will alternate between the missions of the Rebel Alliance, flew the normal range of Ala-X and Ala-B and so on, and the missions of the family, usually flown in a freight Azzameens’ Sabra including an impressive version of Lessing YT-1300 freighter most know that the Millennium Falcon. Towards the end of the game, the lines are blurred, and both ships and cargo Azzameen brothers Ace and Aeron Emon begin to play a more direct role in rebel activities. When the Bothan spy Ace accompanied earlier in one of the best missions always inform the Star Pendant Alliance of Death II, the plan to infiltrate the bunker on Endor begins to take shape and Ace has the task of transporting the strength of General Madine Advanced 327 Imperial attack, where they will steal the Tydirium and, above all, their codes settlement.

A funny thing about this mission is that it offers a very clever, very subtle suggestion that the name comes from Tydirium: once you have docked with the outpost and adorable bunch of pixels that make up the command escapes, running the many other shuttles parked in the area reveals names like Mercurium, Xyridium, and so on, it seems this series of shuttles has been appointed to the various theoretical and mineral elements. This was confirmed later by Wizards of the Coast complement the role of Kyle Katarn, specifically namedropped “Tydirium” as a mineral.

In any case, things get hairy for a minute, but ultimately the Sabra and Tydirium escape thanks to the timely arrival of Rogue Squadron. Interestingly, another stage role was written a little later he called “transfer theft”, and in fact uses the Frontier Wrestling Alliance mission as the basis for a story about the attack force itself.

Everything would be hunky-dory, if it were not for the intervention of another video game, Rogue Leader, just a couple of years after Frontier Wrestling Alliance. This time, Wedge Antilles, Rogue Leader holder must sneak Imperial Naval Academy Prefsbelt IV and steal the shuttle itself, while flying cover. While the game is remarkable, as there are a number of different ways the mission can play out depending on the time of day clock gaming system is developed and if you decide to meet a handful of secondary objectives, history itself is quite insignificant Wedge goes, it causes an uproar, and flees.

So the mission seems at first glance that there directly to the Frontier Wrestling Alliance opposition, and, in fact, a Retcon tried to cross sections of whole books, which states that only the codes were stolen in the Frontier Wrestling Alliance not service current transport, but since these were the days when Star Wars does not restart, holocron Guardian Leland Chee finally decreed that have happened both stories as presents, and robbery was the Frontier Wrestling Alliance before. In other words, the official history of the Tydirium shuttle in what is now the Legends was stolen from Outpost 327 and escorted by Rogue Squadron, only to be retaken by the Empire almost immediately and taken to Prefsbelt IV universe, where Wedge would then break in and steal everything again. then the shuttle was transported to Endor and recording under his real name, despite the feelings of Vader, he did not raise any red flags at all. You go figure.


The Expanded Universe Explains, Vol. IX – The Shuttle Tydirium

The Tydirium

The Tydirium was a Sienar Fleet Systems Imperial Lambda-class shuttle, which operated as a courier and a transport in the Prefsbelt system. It was later present at Outpost 327 over Zhar, where it was captured by General Crix Madine of the Alliance to Restore the Republic.

Shuttle Tydirium Approaches Endor – Return of the Jedi

Madine hoped to use the shuttle and the clearance codes it carried to have a strike team infiltrate the Forest Moon of Endor, around which orbited a new Imperial battlestation, the second Death Star. The strike team would then, if all went as planned, deactivate the deflector shield protecting the still-under-construction Death Star.

Despite this effort, the ship itself later fell into Imperial hands, and was held at the Prefsbelt Naval Academy on Prefsbelt IV. With Madine once again coordinating the operation, the shuttle was once again stolen, this time by pilot Wedge Antilles. The Tydirium was then used by General Han Solo and his strike team to infiltrate the moon of Endor, as planned.

His mission to deactivate the deflector shield was coordinated by General Brenn Tantor, who stayed aboard the Tydirium while the rest of the team ventured out onto the moon. Following the Battle of Endor, in which the Death Star II was destroyed, Solo used the Tydirium to capture the Imperial Star Destroyer Accuser.
