“…SPIX and one of the SpoC variants use similar sLiSCP-light- [256] permutations. Differential characteristics [214][215][216] and distinguishers [217] on sLiSCPlight [256], summarized in Section 3.2.26, are also applicable to SPIX.…”

“…Security Analysis. Kraleva et al [214][215][216] described differential characteristics of sLiSCPlight- [256] and sLiSCP-light- [192] that covered six, seven, or nine steps, as well as corresponding attacks on reduced-step SpoC-64 and SpoC-128 variants. A key recovery attack on full SpoC-64 was presented that does not violate the security claims due to large data requirements.…”

The National Institute of Standards and Technology (NIST) initiated a public standardization process to select one or more Authenticated Encryption with Associated Data (AEAD) and hashing schemes suitable for constrained environments. In February 2019, 57 candidates were submitted to NIST for consideration. Among these, 56 were accepted as firstround candidates in April 2019. After four months, NIST selected 32 of the candidates for the second round. In March 2021, NIST announced 10 finalists to move forward to the final round of the selection process. The finalists are ASCON, Elephant, GIFT-COFB, Grain-128AEAD, ISAP, PHOTON-Beetle, Romulus, SPARKLE, TinyJAMBU, and Xoodyak. This report describes the evaluation criteria and selection process, which is based on public feedback and internal review of the second-round candidates.

“…Both libraries support many block ciphers and several distinguishing attacks, namely differential and linear cryptanalysis in CryptoSMT and (related‐key) differential, RX, and (related‐key) impossible‐differential in ArxPy, and they have been used in multiple studies, for example, Refs. [23–26] or [27–30]. However, these two libraries present severe limitations.…”

Automated search methods based on Satisfiability Modulo Theory (SMT) problems are being widely used to evaluate the security of block ciphers against distinguishing attacks. While these methods provide a systematic and generic methodology, most of their software implementations are limited to a small set of ciphers and attacks, and extending these implementations requires significant effort and expertise. In this work, the authors present cryptographic algorithms for distinguishing attacks (CASCADA), an open-source Python library to evaluate the security of cryptographic primitives, specially block ciphers, against distinguishing attacks with bit-vector SMT solvers. The tool CASCADA implements the bit-vector property framework herein proposed and several SMT-based automated search methods to evaluate the security of ciphers against differential, relatedkey differential, rotational-XOR, impossible-differential, impossible-rotational-XOR, related-key impossible-differential, linear and zero-correlation cryptanalysis. The library CASCADA is the result of a huge engineering effort, and it provides many functionalities, a modular design, an extensive documentation and a complete suite of tests.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Lightweight Cryptographic Hash Functions: Design Trends, Comparative Study, and Future Directions

et al. 2022

View full text Add to dashboard Cite

The emergence of the Internet of Things (IoT) has enabled billions of devices that collect large amounts of data to be connected. Therefore, IoT security has fundamental requirements. One critical aspect of IoT security is data integrity. Cryptographic hash functions are cryptographic primitives that provide data integrity services. However, due to the limitations of IoT devices, existing cryptographic hash functions are not suitable for all IoT environments. As a result, researchers have proposed various lightweight cryptographic hash function algorithms. In this paper, we discuss advanced lightweight cryptographic hash functions for highly constrained devices, categorize design trends, analyze cryptographic aspects and cryptanalytic attacks, and present a comparative analysis of different hardware and software implementations. In the final section of this paper, we highlight present research challenges and suggest future research topics related to the design of lightweight cryptographic hash functions.
