Intel’s SGX coughs up crypto keys when scientists tweak CPU voltage

To counter the growing sophistication of computer attacks, Intel and other chip makers have built digital vaults into CPUs to segregate sensitive computations and secrets from the main engine computers use. Now, scientists have devised an attack that causes the Software Guard Extensions-Intel’s implementation of this secure CPU environment to divulge cryptographic keys and induce potentially dangerous memory errors.
