The CLEFIA block cipher has a generalised Feistel structure, which has been an ISO international standard since 2012. In 2014 Su et al. proposed a white-box CLEFIA implementation with a white-box table for an S-box, and in 2020 Yao et al. ...

The Whirlwind hash function was proposed by Barreto et al. (Des Codes Cryptogr 56(2–3):141–162, 2010, https://doi.org/10.1007/s10623-010-9391-y). In this paper, we focus on preimage and collision attacks on reduced-round Whirlwind. With the help ...${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$

The hash function is an efficient source of the integrity and authentication of input text and other data messages (image & audio-video) in the cryptography field. Existing hashing algorithms are time-consuming and vulnerable to ...

The KECCAK hash function was selected by NIST as the winner of the $\mathtt{SHA}-\mathtt{3}$ competition in 2012 and became the $\mathtt{SHA}-\mathtt{3}$ hash standard of NIST in 2015. On account of $\mathtt{SHA}-\mathtt{3}$’s importance in theory and applications, the analysis of its security has ...$\mathtt{}\mathtt{}$$\mathtt{}\mathtt{}\mathtt{}$$\mathtt{}\mathtt{}\mathtt{}$$\mathtt{}\mathtt{}$

This paper introduces an improved version of the secure hash algorithms, SHA-1, and SHA-2. The proposed work produces a strengthened secure hash design using the fusion between the SHA-1 and SHA-2 hash standards. This design helps to ...

With the urgency of the threat imposed by quantum computers, there is a strong interest in making the signature schemes quantum resistant. As the promising candidates to ensure post-quantum security, symmetric-key primitives, in particular the ...

Since Chow et al. introduced white-box cryptography with a white-box implementation of the AES block cipher in 2002, a few attacks and improvements on Chow et al.’s white-box AES implementation have been presented, particularly Lepoint et al. gave ...${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$

Side-channel collision attacks have shown good efficiency on breaking unprotected or reused-mask implementations of block ciphers. Depending on the relationship between “Hamming distance of values” and “average distance of traces”, ...

The SM4 block cipher has a 128-bit block length and a 128-bit user key, formerly known as SMS4. It is a Chinese national standard and an ISO international standard. White-box cryptography aims primarily to protect the secret key used in a ...${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$${\mathrm{}}^{\mathrm{}}$

At EUROCRYPT 2021, Bao et al. proposed an automatic method for systematically exploring the configuration space of meet-in-the-middle (MITM) preimage attacks. We further extend it into a constraint-based framework for finding exploitable MITM ...

In this paper, we study dedicated quantum collision attacks on SHA-256 and SHA-512 for the first time. The attacks reach 38 and 39 steps, respectively, which significantly improve the classical attacks for 31 and 27 steps. Both attacks adopt the ...

RIPEMD-160 is an ISO/IEC standard and has been applied to generate the Bitcoin address with SHA-256. Due to the complex dual-stream structure, the first collision attack on reduced RIPEMD-160 presented by Liu, Mendel and Wang at Asiacrypt 2017 ...

Rising demands for increased performance, lower energy consumption, connectivity and programming flexibility are nowadays driving the platforms, so-called Multi-Processor Systems-on-Chips (MPSoCs). These platforms are composed of ...

Bogdanov and Kizhvatov proposed the concept of test of chain, but they didn’t give a practical scheme. Wang et al. proposed fault tolerant chain to enhance test of chain and gave a practical scheme. However, the attack efficiency of Correlation ...${}_{\mathit{}}$

The single-shot collision attack on RSA proposed by Hanleyï źetï źal. is studied focusing on the difference between two operands of multipliers. There are two consequences. Firstly, designing order of operands can be a cost-effective countermeasure.We ...

In this work, we apply the sliced biclique cryptanalysis technique to show 8-round collision attack on a hash function based on 4-branch, Type-2 Generalized Feistel Network (Type-2 GFN). This attack is generic and works on 4-branch, Type-2 GFN ...

We analyze the GrØstl-0 hash function, that is the version of GrØstl submitted to the SHA-3 competition. This paper extends Peyrin's internal differential strategy, that uses differential paths between the permutations P and Q of GrØstl-0 to construct ...

The GOST hash function, defined in GOST R 34.11-2012, was selected as the new Russian standard on August 7, 2012. It is designed to replace the old Russian standard GOST R 34.11-94. The GOST hash function is an AES-based primitive and is ...

NTRU cryptosystem has been widely used in microsystems with low performance in computation. In 2010 Lee et al. gave several power analysis attacks on NTRU and three countermeasures, where they argued that only second-order power analysis can break their ...

SM3 [12] is the Chinese cryptographic hash standard which was announced in 2010 and designed by Wang et al. It is based on the Merkle-Damgard design and its compression function can be seen as a block cipher used in Davies-Meyer mode. It uses message ...
