Only IEEE standards older than 12 months are available to the public in general (through the "Get IEEE 802 Program"). So the new 802.11i and 802.1X-2004 standards documents are not available. You must be a IEEE participant to get hold of any drafts/work in progress papers (which actually isn't that hard - just join a mailing list and say you are interested).
