In the case you mention, I would not bring up experience under another name. What you did was fraudulent and thus not something you want a potential employer to know about.
In another situation (say a woman who changed her name with a marriage or divorce or a transgender person), if you need them to know the work was under a different name becasue that is the name your references would know you as, I would not address this in the resume at all but in the cover letter. You could use language such as
My references from CompanyXYZ would know me under my previous name of
or (the transgendered who had a different name might need a longer explanation)
In May 2010, I underwent a change of gender. My work history until
that date was under the name of John Smith and that is the name my
references from that time will know me by.
