Extended Substitution Cipher Chaining mode (ESCC)

Mohamed Abo El-Fotouh, Klaus Diepold

Abstract: In this paper, we present a new tweakable narrow-block mode of operation, the Extended Substitution Cipher Chaining mode (ESCC), that can be efficiently deployed in disk encryption applications. ESCC is an extention of Substitution Cipher Chaining mode (SCC)~\cite{scc}. Unlike SCC, ESCC is resistant to the attacks in~\cite{scc_attack,scc_attack2}.

Category / Keywords: secret-key cryptography / ESCC, SCC, AES, modes of operation
