Differential characteristics Nested Monte-Carlo Search ARX ciphers
2018/11/9
In this paper we focus on differential cryptanalysis dedicated to a particular class of cryptographic algorithms, namely ARX ciphers. We propose a new algorithm inspired by the Nested Monte-Carlo Sear...

Little theoretical work has been done on (n,m)(n,m)-functions when n2nn2en though these functions can be used in Feistel ciphers, and actually play an important role in several block cipher...
Towards Key-Dependent Integral and Impossible Differential Distinguishers on 5-Round AES
AES Key-Dependent Integral
2018/8/10
Reduced-round AES has been a popular underlying primitive to design new cryptographic schemes and thus its security including distinguishing properties deserves more attention. At Crypto'16, a key-dep...

Symmetric-key cryptography differential cryptanalysis lightweight cryptography
2018/7/19
Resistance against differential cryptanalysis is an important design criteria for any modern block cipher and most designs rely on finding some upper bound on probability of single differential charac...

Post-quantum cryptography Hash-based signatures DPA
2018/7/16
Quantum computing threatens conventional public-key cryptography. In response, standards bodies such as NIST increasingly focus on post-quantum cryptography. In particular, hash-based signature scheme...
In this work, we discuss two notions of differential equivalence on Sboxes. First, we introduce the notion of DDT-equivalence which applies to vectorial Boolean functions that share the same differenc...

Emerging technologies with the requirement of small size and portability, such as Internet-of-Things devices, represent a good target for physical attacks, e.g., fault attacks. These attacks often aim...
We present various differential fault attack schemes for the RECTANGLE-80 and demonstrate how initially we started from a 80-bit fault to a single word fault scheme. This was mainly due to a different...
