In the "Gates not his cocky self at RSA conference" Roger Smith article,
the author says:
[Adi Shamir] cautioned that many of the current generation of
Intel processors that use multi-threading and multi-core
technology seem to be vulnerable to timing attacks that can
use unprivileged threads to find keys stored in their caches.
I hadn't known that one process could read the memory of a second
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?
