Tag Second-preimage Attack against π-cipher
The π-cipher is one of the candidates of the CAESAR competition. One of the advertised features of the π-cipher is tag second-preimage resistance: it should be hard to generate a message with a given tag, even for the legitimate key holder (insider ...

Security issues of telemedicine‐based secure transmission of medical images find a very thin line drawn between diagnostic acceptability and cybersecurity. Partial but imperfect solutions emerge. JPEG2000 and HEVC concentrate only on compression, failing to provide any security consideration.

Preimage Attack on Parallel FFT-Hashing [PDF]
Parallel FFT-Hashing was designed by C. P. Schnorr and S. Vaudenay in 1993. The function is a simple and light weight hash algorithm with 128-bit digest.

ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art
An anti‐counterfeiting system for physical art based on Ethereum blockchain and near‐field communication technology is proposed and implemented. The system leverages the use of Ethereum smart contracts and inter‐planetary file system to store artworks’ certificate of authenticity, and display them in a mobile app called ArtProtect.

Abstract This systematic literature review examines the implementation and analysis of zk‐SNARK, zk‐STARK, and bulletproof non‐interactive zero‐knowledge proof (NIZKP) protocols in privacy‐preserving applications across diverse sectors. Examining 41 research works obtained through the systematic search queries and filtering criteria published from 2015

Preimage and pseudo-collision attacks on 29-step SM3 hash function with padding [PDF]
The security of SM3 hash function was revaluated by using the meet-in-the-middle attack. The preimage and pseudo-collision attack on 29-step SM3 hash function (from the 1-st step) with padding was presented.

Improved Preimage Attacks on 4-Round Keccak-224/256
This paper provides an improved preimage attack method on standard 4-round Keccak-224/256. The method is based on the work pioneered by Li and Sun, who design a linear structure of 2-round Keccak-224/256 with 194 degrees of freedom left.

Badly approximable grids and k$k$‐divergent lattices
Abstract Let A∈Matm×n(R)$A\in \operatorname{Mat}_{m\times n}(\mathbb {R})$ be a matrix. In this paper, we investigate the set BadA⊂Tm$\operatorname{Bad}_A\subset \mathbb {T}^m$ of badly approximable targets for A$A$, where Tm$\mathbb {T}^m$ is the m$m$‐torus. It is well known that BadA$\operatorname{Bad}_A$ is a winning set for Schmidt's game and hence

Multi‐hop anonymous payment channel network based on onion routing
To solve the payment channel network path privacy problem, we analyse the multi‐hop anonymous and privacy‐preserving payment channel network scheme and propose a multi‐hop anonymous payment channel network based on onion routing based on it. The scheme removes the routing assumptions of the original scheme, designs an onion routing‐based payment ...

Picard sheaves, local Brauer groups, and topological modular forms
Abstract We develop tools to analyze and compare the Brauer groups of spectra such as periodic complex and real K$K$‐theory and topological modular forms, as well as the derived moduli stack of elliptic curves. In particular, we prove that the Brauer group of TMF$\mathrm{TMF}$ is isomorphic to the Brauer group of the derived moduli stack of elliptic ...
