Our main result is that RCB fails to provide authenticity, even in the absence of leakage. Keywords: authenticated encryption, leakage-resilience, block cipher, ...
This paper presents several issues of the RCB block cipher mode and results show that RCB fails to provide authenticity, even in the absence of leakage.
The first published “leakage resilient” AE scheme is the RCB block cipher mode. As it turns out, RCB is insecure, even if there is no side channel for the ...
RCB is inherently vulnerable to Denial-of-Service (DoS) attacks, and. RCB is insecure when one key is used for full-duplex communication. For the worst,. RCB is ...
RCB fails to provide secure authenticated encryption since it cannot provide. INT-CTXT security. We stress that none of the issues 2–4, 6 applies to OCB ...

Leakage resilient cryptography wants to provide security against side channel attacks. In this paper, we present several issues of the R C B \mathsf {RCB} ...
In this paper, we propose a hash-based authenticated nonce-misuse resistant encryption, namely HANMRE which is adaptable for a lightweight leakage resilient ...
The security of modern cryptosystems relies on the secrecy of the keys. Against the expectation that the keys used in cryptographic algorithms are perfectly ...
