Near Collision Attack Against Grain V1
Daniel Patrick Collins, Subhadeep Banik, Willi Meier
A near collision attack against the Grain v1 stream cipher was proposed by Zhang et al. in Eurocrypt 18. The attack uses the fact that two internal states of the stream cipher with very low hamming distance between them, produce similar keystream sequences ...
2023Atom: A Stream Cipher with Double Key Filter
Andrea Felice Caforio, Subhadeep Banik, Willi Meier
It has been common knowledge that for a stream cipher to be secure against generic TMD tradeoff attacks, the size of its internal state in bits needs to be at least twice the size of the length of its secret key. In FSE 2015, Armknecht and Mikhalev however ...
