- sweis 13y agoYes, TRESOR can help against cold boot attacks, which are passive and read-only. Several physical attack vectors can modify the contents of memory, thus compromise the software stack and divulge keys kept in registers or cache. Our approach at PrivateCore is to fully encrypt main memory with an authenticated cipher mode and keep the software stack pinned in cache. An attacker able to physically modify memory can only conduct a DoS attack by inserting junk data.
