I am trying to find the type of fonts from this definition definition. Specially for the words: Combine,Reveal,gen,enc,dec. An experienced user might know this font

Side note: that has to be one of the most hard-to-decipher definitions I've ever stumbled upon. And not because of the typography - that part's fine - but because of all the cross-referencing. (Might have to do with the fact that it's completely out of my field, too :P) –  Tomas Lycken Jun 1 '12 at 1:30

@doncherry I believe it's not "how to find the name of the fonts", but "how do I produce those font variations with LaTeX". The actual fonts used are not relevant, IMO. –  egreg Jun 1 '12 at 8:59
@egreg: Good point. That makes me think of a one-catches-all question "What are the different fonts that I can use in math mode?", would that make sense? –  doncherry Jun 1 '12 at 9:02

That "gen" is obtained with \mathsf, while "Reveal" with \mathtt. Here's a way to write that passage; I added some personal commands in order to abstract the font assignments, so that changing them is a matter of only changing the definition in the preamble.





A contract function \(f_{\contract}\colon\Set{P}^{*}\to\Set{R}\) is said
to support cryptodatabases processing under the encryption scheme
\(\langle\afunc{gen},\afunc{enc},\afunc{dec}\rangle\) if the following
condition holds: there exist two functions \(\bfunc{Combine}\) and
\(\bfunc{Reveal}\) so that, for any \(n\in\Set{N}\) and any
\(m_{1},\dots,m_{n}\in\afunc{D}_{\contract}\), if
\(\langle pk,sk\rangle\gets\afunc{gen}(1^n)\),
\(c_{i}\gets\afunc{enc}(pk,m_{i})\) for \(i=1,\dots,n\) and
\(c\gets\bfunc{Combine}(c_{1},\dots,c_{n})\), then we have
