Applications of SAT Solvers to AES key Recovery from Decayed Key Schedule Images
Cold-boot attacks decayed memory SAT solvers
2010/7/13
Cold boot attack is a side channel attack which exploits the data remanence property of random access memory (RAM) to retrieve its contents which remain readable shortly after its power has been remov...
Improved Single-Key Attacks on 8-round AES

2010/2/1
Differential Fault Analysis (DFA) against AES has been actively studied
these years. Based on similar assumptions of the fault injection, different DFA attacks
against AES have been proposed. Howeve...
