  Optimizing Search Strategy of Large Password Space

  Description: The traditional password attacking is based on the time memory tradeoff attack. Both its time complexity and space requirement do not exceed the exhaustive password searching complexity. But it did not consider the non-uniformly distributed passwords created by human being. Our target is to design a more efficient password cracking method considering the non-uniform distribution of the passwords.My Responsibility: Extract the characteristic of the structure from large currently leaked passwords and estimate the occurrence for each structure. Construct a pre-computed table which covers most of those passwords with high probability of occurrence. Apply the model to real world password and make a comparison with the existing rainbow attack. Published a related paper on a journal.Main tech: C++, Rainbow attack, time memory tradeoff attack, Indexing algorithm. Show less

  The Design of Authentication Algorithm

  Design a hardware oriented stream cipher based a new structure. It offers both confidentiality and integrity of a message. We have designed a cipher called 'Sablier'. Its implementation only uses bit XOR, bit AND and word-oriented rotation. We submit it to the international CAESAR competition and now the competition is in the first round evaluation. My Responsibility: Design the new structure of the algorithm. Design and implement the authentication part of the cipher.Main tech: C++, Message Authentication Code, Toeplitz matrix. Show less
