Protect Linux from cold boot attacks with TRESOR
|
|
While reading an interesting Blog I discovered a new treasure: TRESOR, in short TRESOR is a secure implementation of AES which is resistant against cold boot attacks and other attacks on main memory. Contrary to popular assumption, DRAMs used in most modern computers retain their contents for seconds to minutes after power is lost, even at operating temperatures and even if removed from a motherboard. Although DRAMs become less reliable when they are not refreshed, they are not immediately erased, and their contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images. This is a cold based attack.
