On Non-Monotonicity of the Success Probability in Linear Cryptanalysis
Linear cryptanalysis success probability non-monotonicity
2018/5/28
Like any other cryptanalytic attack, the success rate of a linear attack is expected to improve as more data becomes available. Bogdanov and Tischhauser (FSE 2013) made the rather surprising claim tha...
Related-Key Linear Cryptanalysis on SIMON
related-key attack linear cryptanalysis linear key schedule
2018/3/7
We present a general framework of the related-key linear attack that can be applied to a class of block ciphers including the key-alternating iterative ones with linear or affine key schedules. In con...

Linear cryptanalysis Multiple linear cryptanalysis Multi-key linear cryptanalysis
2017/3/6
This paper deals with linear approximations having absolute bias smaller than 2−n22−n2 which were previously believed to be unusable for a linear attack. We show how a series of observatio...
