I recently implemented SSARES directly in python and also added parallelism to the searching. We can now search the a large inbox (1000+) messages in about 2-4 minutes. Technically, this could be done on a large scale and be practical, since my implementation is not fully optimized nor free of bugs.
The implementation is available on my web site, http://fling.seas.upenn.edu/~aviv/wiki/index.php?n=SSARESApp.SSARESApp as well as some current benchmarks. I am not a cryptographer (so implementation may not be perfect), nor do I guarantee that the code doesn't have bugs. This is grad-ware and for research purposes only. Yet, as a proof of concept, feel free to play around with it and let me know what you think. I can supply more python scripts for searching and what not if anyone wants. thanks, adam On Sun, Jun 1, 2008 at 8:09 PM, Angelos D.
