Re: [Taler] Fault attacks on RSA in libgcrypt

[Jeff Burdges]

I found an article which provides the same sort of fault protections
with a randomized CRT algorithm.  I'd expect it gives stronger
protections against timing attacks, etc., even if fault attacks prove
not to be realistic. 
http://dl.acm.org/citation.cfm?doid=1873548.1873556

This is probably more the sort of thing one should be doing.  It appears
the random numbers injected should be quite small, making this scheme
fairly fast.  This particular paper however only really focuses on fault
attacks.  

It would be good to see this or similar schemes evaluated for timing
attack protections though, as folks understandably care way more about
timing than about fault attacks. 

Best,
Jeff
