[ 1 ] - Cryptanalysis of some first round CAESAR candidates

ΑΕS _ CMCCv₁, ΑVΑLΑNCHEv₁, CLΟCv₁, and SILCv₁ are four candidates of the first round of CAESAR. CLΟCv₁ is presented in FSE 2014 and SILCv₁ is designed upon it with the aim of optimizing the hardware implementation cost. In this paper, structural weaknesses of these candidates are studied. We present distinguishing attacks against ΑES  _ CMCCv₁ with the complexity of two queries and the success ...

[ 2 ] - Artemia: a family of provably secure authenticated encryption schemes

Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...

[ 3 ] - An Introduction to Differential Computation Analysis (DCA) on the withe-box cryptography algorithms

Advances in information and communication technologies lead to use of some new devices such as smart phones. The new devices provide more advantages for the adversaries hence with respect to them, one can define with-box cryptography. In this new model of cryptography, designers try to hide the key using as a kind of implementation. The Differential Computation Analysis (DCA) is a side channel ...

[ 4 ] - Some observations on a lightweight authentication scheme with capabilities of anonymity and trust in Internet of Things (IoT)

Over the last years‎, ‎the concept of Internet of Things (IoT) leads to a revolution in the communications of humans and things. ‎Security and efficiency could be the main challenges of that communication‎‎. ‎‎On the other hand, ‎ authenticity and confidentiality are two important goals to provide desired security in an information system‎, including IoT-based applications. An Authentication an...
