Multivariate Profiling of Hulls for Linear Cryptanalysis
IACR Transactions on Symmetric Cryptology
Extensions of linear cryptanalysis making use of multiple approximations, such as multiple and multidimensional linear cryptanalysis, are an important tool in symmetric-key cryptanalysis, among others being responsible for the best known attacks on ciphers such as Serpent and present. At CRYPTO 2015, Huang et al. provided a refined analysis of the key-dependent capacity leading to a refined key equivalence hypothesis, however at the cost of additional assumptions. Their analysis was extended bydoi:10.46586/tosc.v2018.i1.101-125 fatcat:i2a2jqaonfa6xjffkfksk3im5q
