One unspoken issue has always been whether or not the Chinese government
has deliberately sabotaged the spec, presumably for domestic

been pointed out, the SMS4 block cipher was disclosed earlier this year.
Nonetheless, many of my concerns about the security of WAPI remain.
We already have a perfectly good solution out there; 802.11i is a good
scheme, and

Today in slashdot (http://it.slashdot.org/it/06/06/12/0710232.shtml) there
was an article about China wanting to get WAPI accepted as a new wireless
security standard. Has anyone looked at it?

Hi Richard,
I have not looked at WAPI, but they have been trying to get it approved for a
number of years, check out http://en.wikipedia.org/wiki/WAPI (has link to
algorithm) and http://www.foxnews.com/story/0,2933,199082,00.html.

Hi Folks,
My apologies on stating that the Wiki page had a link to the algorithm. I saw
the link but didn't click on it to see if in fact there was a description of
the actual algorithm.
