Hello cryptogeeks,
does anyone have idea for KATAN/KTANTAN block cipher.Got any C code for it???

No, I haven't heard of that one, but Google and Wikipedia have a lot of information on all kinds of ciphers. Wikipedia has an entire portal dedicated to Cryptology - neat stuff.

With all the interest in protecting info these days, you should have no problem Googling successfully for it.

(Or do you already HAVE info on it and edging up the search engine optimization for that tag?) ;)

Hey well wiki doent have a page of it and googling is not helping

Google has it:

This is a paper on Quark, which uses the Katan block cipher:

This is a C program that implements it:

This is a Linux program, so the free d/l Notepad light is good to view it, not Windows notepad (where the lines are horribly goofy. WinRAR, etc., will decompress, as will Linux distro's. (it's a tar.gz file.)

I haven't run into this one before, but it's a lightweight and fast hash block cipher. RFID apparently is a good use for it.
