MorganS:
What does that tell you about a large crypto library that the Arduino side only needs to compile and link a few functions to do the 'signing'' side of the transaction?
A few functions. How quaint.
You may as well look at the size of the math.h library on disk and claim that won't fit on an Arduino.
When elliptic curve functions have been added to "math.h" let me know. Until then that is a false analogy.
But, there is no point discussing hypothetical with you when there is a trivial practical path to follow...

I have implemented Digital Signature using PBC and GMP libraries.( I have taken the code from the PBC library as liked above.)My code works correctly when i compile it on Visual Studios 2010.
Post the MAP file. Armed with that it will be possible to assess the size processor.
