WebThis paper reduces the cryptanalysis of a stream cipher to solving a system of multivariate equations that is overdefined (much more equations than unknowns), and adapts the XL method, introduced at Eurocrypt 2000 for overdefined quadratic systems, to solving equations of higher degree. 224 Highly Influenced PDF WebMar 14, 2024 · Linear cryptanalysis is a general style of cryptanalysis based on discovering affine approximations to the element of a cipher. Attacks have been produced for block ciphers and stream ciphers. Linear cryptanalysis is one of the two most broadly used attacks on block ciphers and the other being differential cryptanalysis.
