Software Solution: Against Cold Boot Attack

DRAM is an important memory of a computer. Microprocessor loads the data requested by the user into DRAM before processing the data. Hence, DRAM contains important information in a computer. Recently, researchers discovered that DRAM is vulnerable to attack that is called Cold boot attack. DRAM contents can be recovered even after the computer has been powered off for several minutes. The information obtained can be often use to break the disk encryption system such as File vault. In this paper, we proposed the methodology which explains the complete process and describe the safeguard methods. We design a system keeping few things in our mind the accessibility for the user and Security. This System is defines as a software solution to the cold boot problem. We also used additional feature to prevent DRAM from the machine replacement. The System is designed as the procedure to secure the encryption key and prevent the machine from attack.
