"We are looking at something verging on the incredibly bizarre. As she got older she got shorter and broader and was reduced to a giant gelatinous blob, carrying many thousands of eggs," he says.

"Her shape was likely to have affected her behaviour and ability to hunt. I can't imagine her jetting herself around in the water at any great speed, and she was too gelatinous to have been a fighting machine.

"It's likely she was just blobbing around the seabed carrying her brood of eggs, living on dead fish, while her mate was off hunting."

One source at the Knight Center for Digital Excellence notes, "The new network owners are supposed to have a much more sustainable business model." Supposed to. Later, "Network Acquisition Company, which acquired the network, hasn't talked publicly about the details of its new plan, but it has hinted that its strategy will differ from EarthLink's." Hasn't talked publicly. Then, "[NAC and Tropos] spokespeople said the companies would talk more about the network later this month when details of the new business plan are ready." Huh.

Reardon explains digital divide issues and looks into what Wireless Philadelphia has been up to, although doesn't note that delays in EarthLink's deployment and other factors have led to just a few hundred individuals that have been assisted by the non-profit; numbers may have changed, but that was as of a few months ago. Still, Wireless Philadelphia has apparently diversified its funding sources--Reardon cites 30 now.

I think we're still coming off the doldrums of August.

So that's what he asked for, and that's what he got. And now it's time to create some cryptographic applications for the rings. Cory and I are holding an open contest for the cleverest application.

I don't think we can invent any encryption algorithms that will survive computer analysis -- there's just not enough entropy in the system -- but we can come up with some clever pencil-and-paper ciphers that will serve them well if they're ever stuck back in time. And there are certainly other cryptographic uses for the rings.

Here's a way to use the rings as a password mnemonic: First, choose a two-letter key. Align the three wheels according to the key. For example, if the key is "EB" for eBay, align the three wheels AEB. Take the common password "PASSWORD" and encrypt it. For each letter, find it on the top wheel. Count one letter to the left if there is a dot over the letter, and one letter to the right if there is a dot under it. Take that new letter and look at the letter below it (in the middle wheel). Count two letters to the left if there is a dot over it, and two letters to the right if there is a dot under it. Take that new letter (in the middle wheel), and look at the letter below it (in the lower wheel). Count three letters to the left if there is a dot over it, and three letters to the right if there is a dot under it. That's your encrypted letter. Do that with every letter to get your password.

"PASSWORD" and the key "EB" becomes "NXPPVVOF."

It's not very good; can anyone see why? (Ignore for now whether or not publishing this on a blog makes it no longer secure.)

How can I do that better? What else can we do with the rings? Can we incorporate other elements -- a deck of playing cards as in Solitaire, different-sized coins to make the system more secure?

Post your contest entries as comments to Cory's blog post -- you can post them here, but they're not going to count as contest submissions -- or send them to cryptocontest@craphound.com. Deadline is October 1st.

Good luck, and have fun with this.

It's a man-in-the-middle attack. "The Internet's Biggest Security Hole"  has been that interior relays have always been trusted even though they are not trustworthy.

That could apply word for word to how MQ Series and other enterprise messaging systems are deployed. Let's say you are a bank and have been happily running your business on a mainframe for decades. Life is good, come in at 9 leave at 5, count the cash. Then some dotcommer comes along and tells you that you need to get online. What are you gonna do? Rewrite your whole system from scratch? Hard to make that case.
