Spectre

Prosseco / 6 Antworten / Flachansicht Nickles

Hallo an alle,

Tja so ist es.

"In the context of Spectre and Meltdown, leveraging coherence invalidations enables a Prime+Probe attack to achieve the same level of precision as a Flush+Reload attack and leak the same type of information. By exploiting cache invalidations, MeltdownPrime and SpectrePrime -- two variants of Meltdown and Spectre, respectively -- can leak victim memory at the same granularity as Meltdown and Spectre while using a Prime+Probe timing side-channel.

Where Meltdown and Spectre arise by polluting the cache during speculation, MeltdownPrime and SpectrePrime are caused by write requests being sent out speculatively in a system that uses an invalidation-based coherence protocol."

Ich sage nur Princeton University and Nividia.
