There's no support for anything like that. All pages are visible to everyone at all times, unless you set up the global read whitelist, which applies equally to those without read permssiion. If you are stuck there, you can't edit or perform any other actions than view of those whitelisted pages.
MediaWiki is *not* designed for complex restricted read access. If you require this you should use software designed for it.
or patch MediaWiki with this : http://meta.wikimedia.org/wiki/Page_access_restriction_with_MediaWiki
