Comment on Tresor – CPU-only AES implementation resistant to RAM cold-boot attacks (2011)Comments−_antares10yClever but useless. Cold boot attack does not work on RAM with DDR3+. Pretty much all new computers are safe. http://superuser.com/a/464396−rdl10yPlenty of other attacks work, such as sniffing memory lines on a running system.−_antares10yThat is not CBA so it's not on topic. Extracting encryption keys on a running system is completely other vector attack and I doubt using registers is much safer than RAM in such case. Might be wrong though. :)
