In the "Gates not his cocky self at RSA conference" Roger Smith article,
the author says:=20
[Adi Shamir] cautioned that many of the current generation of=20
Intel processors that use multi-threading and multi-core=20
technology seem to be vulnerable to timing attacks that can=20
use unprivileged threads to find keys stored in their caches.

process running on a different hyper-thread or a different core through
a cleverly timed cache hits (which is what I think this sentence says).
Does anyone have further information on this or mitigation strategies?
