Hey peoples,

Although I don't expect to find many crypto-geeks here, I figured I'd post this anyway. It's a known-plaintext attack on a reduced-round RC5 variant that I discovered recently. Warning: it's written with the assumption that the reader is familiar with the basics of linear cryptanalysis. I plan to extend it to a typical 12 round 32 bit block size in the future, but so far it looks promising. If anyone knows of a paper describing a similar attack, please let me know. Other than that, you may find some other things on my site interesting:

Let me know what you folks think.

Nice. I need to brush up on my crypto :P
