How the Super Bowl Will Reach US Submarines 142

Posted by samzenpus from the davey-jones'-locker-room dept.
Velcroman1 writes "Ever wonder how troops serving abroad in remote locations and even underwater might get to watch the Super Bowl? The very same highly advanced technology used to pass classified drone video feeds will be deployed this Sunday to ensure U.S. troops can see the Super Bowl — - no matter how far away from home they are. The broadcast is the result of a unique media, government and technology partnership with the American Forces Radio and Television Service, Raytheon and the U.S. Air Force. The Global Broadcast Service (GBS) may be normally used to disseminate video, images and other data, but major sporting events have been broadcast over it as well. The system will be 'as small as a laptop, and [equipment] the size of a shoebox and umbrella' yet 'in other places will be projected onto large screens in hangers' like aircraft carriers out at sea, explained Raytheon Intelligence and Information Systems' chief innovation officer Mark Bigham."

        On top of that, it's unlikely that message length has any serious contribution to overall system integrity. The supersecret key is probably only used to exchange a randomly generated temporary key, meaning that even if you break that key, you have successfully discovered the key used solely to broadcast the Super Bowl. You now have a known-plaintext attack against the top-level key, but the value is again limited because your known plaintext is now limited to the length of the temporary key.

      Nonsense. It may be trademarked by the NFL, but it certainly is not copyrighted. If you want to complain about IP law, you might want to take a few minutes to learn the basics. Also, using a trademarked term to refer the the trademarked item is fine. It is only a violation to use it to refer to a confusingly similar item, or in a way that implies endorsement. So it is okay to use the term "The Super Bowl" to refer to ... The Super Bowl.

    How the Super Bowl Will Reach US Submarines

    The actual answer is that the submarines have an antenna that reaches into the air. The title implies that the video signals are sent through sea water to submerged submarines. That is still impossible to do in real-time. The bandwidth (either acoustic or electro-magnetic) is just not available. The acoustic bandwidth is greater than the electro-magnetic but it is still many orders of magnitude lower than what is required for real-time video.

      Right. And on top of that, no submarine is going to hang about at periscope depth for the duration of the game. PD is a dangerous place as you have limited visibility and you're shallow enough for surface vessels to potentially get a piece of the 'scope or even the sail... Stealth also goes down when you have a 'scope and antennas making a wake on the surface. (On top of how exhausting it is for the control room party to maintain PD and a scope watch...)

      Unless they're in port or on surface transit, boats will probably get the game and the score the same way they have for decades... fasties and non-alert boomers will pick it up when they next grab a sked or a satellite pass, alert boomers will pick up whatever gets sent across the wire (VLF).

      Been there done that, got the t-shirt. Though back in the day it was something of a tradition to send the score of important games (especially the Army-Navy game) out as FLASH priority traffic.

With CBC, losing a packet of ciphertext would mess up only adjacent blocks, errors do not propagate. Also, CBC decryption requires only the previous ciphertext, not the plaintext. OFB and CTR are both proven to be IND-CPA (assuming a secure block cipher and your counter is not reused), so they are no weaker than any other mode
