Security of Even–Mansour Ciphers under Key-Dependent Messages
2017
IACR Transactions on Symmetric Cryptology
The iterated Even–Mansour (EM) ciphers form the basis of many blockcipher designs. Several results have established their security in the CPA/CCA models, under related-key attacks, and in the indifferentiability framework. In this work, we study the Even–Mansour ciphers under key-dependent message (KDM) attacks. KDM security is particularly relevant for blockciphers since non-expanding mechanisms are convenient in setting such as full disk encryption (where various forms of key-dependency might
