Abstract :
Data encrypted on your computer should be safe, as long as you´re the only one with the key to the encryption. But one variant of newer¿ and sneakier¿attacks can deduce the key by striking a vulnerable spot: the CPU¿s on-chip memory, called the cache. Software-based attempts to bolster cache security have bad side effects, however, which can severely degrade the computer¿s performance. Now researchers have developed a new kind of cache architecture that neutralizes these attacks. They found that combining the best qualities of the two main types of cache had amazing results: a secure cache that also handles data faster and consumes less power.
