Carnival of Math 二十
And quite a nice Carnival #20 it is. Murray of SquareCircleZ has created a slightly-themed carnival. Since he blogs from Asia, the posts are numbered with Chinese, binary, and our Arabic numerals. That “=” “+” in the title? Nope, it’s the digraph for 20…
If you are here, you’ve probably already seen my contribution (#13).
High School student submitted on encoding…
More interesting? Entry #4 This is the first ever CoM post by a high school student: Andy found a flaw in a polynomial-based encoding system (he shows it is not as strong as it claims. In fact, it would be nice to show that it is not secure, but I don’t know if that is possible, and I am reasonably certain that, even if it were, the math would be beyond my skills.)
Next C o Math is at http://wintershaven.net/ and after that? if you are interested in hosting, contact Alon at alon underscore levy1 at yahoo dot com.

Just so you know, it is secure.
Err.. not “our Arabic numerals”, Jonathan – actually Hindi characters :-)
Hmm. I thought the idea was Hindi, but the actual forms were adapted from the Phoenicians (and called, in English at least, Arabic). Did I get that backwards?
And thanks for the “secure” link. Quite informative and clear.
