Outline of Final Research Achievements

First, we propose a new full plaintext recovery attack. Our proposed attack can recover all plaintext bytes from 233 ciphertexts. Secondly, we propose the interaction between processes running on the different VMs as an alternative means of getting accurate clock cycles. We also cover POODLE attack. It's a kind of Man-in-the-middle attack against SSLv3.0, allowing to extract secure HTTP cookies. We prove the feasibility of this attack with a practical experiment. Thirdly, we propose an attack on high-density knapsack cryptosystem. This attack uses pseudo intermediary plaintext that is not the solution for subset sum problem. We remark about the knapsack cryptosystem the attack is effective. Finally, we propose a new method to find conditional differential characteristics on NLFSR-based stream ciphers. We apply our technique to Grain v1. We show the conditional differential distinguisher on Grain v1 up to 114 rounds and have 240 weak keys.
