Leakage resilient cryptography wants to provide security against side channel attacks. In this paper, we present several issues of the RCB block cipher mode, proposed by Agrawal et al. in [2]. RCB is the first Leakage Resilient Authenticated Encryption (AE) scheme ever presented. In particular, we present a forgery attack that breaks the INT-CTXT security which is a fundamental requirement in the design of AE schemes.
