A New Cost Function for Evolution of S-Boxes
Substitution Boxes (S-Boxes) play an important role in many modern-day cryptographic algorithms, more commonly known as ciphers. Without carefully chosen S-Boxes, such ciphers would be easier to break. Therefore, it is not surprising that the design of suitable S-Boxes attracts a lot of attention in the cryptography community. The evolutionary computation (EC) community also had several attempt...
متن کاملPitfalls in Designing Substitution Boxes
Two signi cant recent advances in cryptanalysis namely the di erential attack put for ward by Biham and Shamir and the linear attack by Matsui have had devastating impact on data encryption algorithms An eminent problem that researchers are facing is to design S boxes or substitution boxes so that an encryption algorithm that employs the S boxes is immune to the attacks In this paper we present...

متن کاملBijective Proofs for Schur Function Identities
In [4], Gurevich, Pyatov and Saponov stated an expansion for the product of two Schur functions and gave a proof based on the Plücker relations. Here we show that this identity is in fact a special case of a quite general Schur function identity, which was stated and proved in [1, Lemma 16]. In [1], it was used to prove bijectively Dodgson’s condensation formula and the Plücker relations, but w...
متن کاملA Reliable Architecture for Substitution Boxes in Integrated Cryptographic Devices
In this paper we propose an on-line self-test architecture for hardware implementations of Advanced Encryption Standard (AES). The solution assumes a parallel architecture and exploits the inherent spatial replications of this implementation. Because Substitution boxes (S-Box) represent the largest hardware in this architecture, we focus on faults affecting these S-Boxes and propose a trade-off...
