Abstract:

In recent years, side-channel attacks have seen significant progress. Among the different types of side-channel attacks, cold boot attack has been considered as a very powerful attack and has created considerable interest among researchers. The attack was discovered by a group of researchers from Princeton University in 2008 and exploits memory remanence property of random access memory. This attack can be used to beat hard disk encryption system, protecting sensitive information of IT products. Success of the attack depends upon detection and correction of sensitive information in the distorted data obtained during execution of the attack. In this thesis, an attempt has been made to improvise key recovery methods so that the attack can be made feasible, even when more errors have been introduced during the execution of attack. Experiments have also been carried out to study and improve the efficacy of these techniques for mounting the attack on realistic hard disk encryption systems like Truecrypt/VeraCrypt.
