Rowhammer Induced Intermittent Fault Attack on ECC-hardened memory

Anirban Chakraborty and Sarani Bhattacharya and Sayandeep Saha and Debdeep Mukhopdhyay

Abstract: Fault attack is a class of active implementation based attacks which introduces controlled perturbations in the normal operation of a system to produce faulty outcomes. In case of ciphers, these faulty outcomes can lead to leakage of secret information, such as the secret key. The effectiveness and practicality of fault attacks largely depend on the underlying fault model and the type of fault induced. In this paper, we analyse the drawbacks of persistent fault model in case of error correction code (ECC) enabled systems. We further propose a novel fault attack called Intermittent Fault Attack which is well suited for ECC-enabled DRAM modules. We demonstrate the practicality of our attack model by inducing single bit faults using pinpointed Rowhammer technique in S-Boxes of block ciphers in an ECC protected system.
