Cryptanalysis of Round-Reduced KECCAK using Non-Linear Structures [PDF]
, 2019 In this paper, we present new preimage attacks on KECCAK-384 and KECCAK-512 for 2, 3 and 4 rounds. The attacks are based on non-linear structures (structures that contain quadratic terms). These structures were studied by Guo et al. and Li et al. to give

Tanda tangan Digital Menggunakan Algoritme Keccak dan RSA
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2016 Just like conventional signatures, digital signatures can be used to prove the authenticity of a document in digital form. In addition, digital signatures can also be used to prove the validity of the author of the document, so that the author of the ...

A Tale of Snakes and Horses: Amplifying Correlation Power Analysis on Quadratic Maps
Transactions on Cryptographic Hardware and Embedded Systems, 2023 We study the success probabilities of two variants of Correlation Power Analysis (CPA) to retrieve multiple secret bits. The target is a permutation-based symmetric cryptographic construction with a quadratic map as an S-box. More precisely, we focus on

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems
International Economic Review, Volume 67, Issue 1, Page 259-285, February 2026.ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.
