Recently NSA published two new algorithms, Simon and Speck. In the abstract they say
The aim of SIMON and SPECK is to fill the need for secure, flexible, and analyzable lightweight block ciphers.
so as the question title says, what does 'analyzable' mean? BTW I found the publication through Schneier's blog post about it.
I haven't had time to read the entire document but haven't found any other references to that particular word. Do they mean the algorithms are easy to be 'proven secure'? Or is it something else? To conclude, this question does invite some degree of discussion, if you feel it doesn't comply with the site's policy, please flag it down. Cheers
