Security Analysis of Speech Perceptual Hashing Authentication Algorithm
International Journal of Security and Its Applications, 2016 Speech perceptual hashing authentication algorithm is an efficient method for content integrity authentication and identity authentication. But the algorithm becomes transparent under the principle of Kerckhoffs which makes the algorithm unsafe. In this paper, the algorithm is encrypted under the principle of Kerckhoffs to protect the security of the ...

Sustainable Development, EarlyView.ABSTRACT Assuring environmental sustainability is essential for the continuity of the ecosystem. Every sector of the economy has some degree of impact on environmental sustainability. The United Nations (UN)’ Sustainable Development Goals (SDGs) have placed these objectives within a broader global framework, offering a global plan aimed at ensuring ...

Short signature based on factoring problem in the standard model
Tongxin xuebao, 2011 A short signature scheme based on factoring problem in the standard model was proposed.To design this sig-nature scheme,the generic construction of fully-secure signatures from weakly-secure signatures and a chameleon hash were employed.A signature in ...

Large-Scale Distributed Learning via Private On-Device Locality-Sensitive Hashing [PDF]
arXiv, 2023 Locality-sensitive hashing (LSH) based frameworks have been used efficiently to select weight vectors in a dense hidden layer with high cosine similarity to an input, enabling dynamic pruning. While this type of scheme has been shown to improve computational training efficiency, existing algorithms require repeated randomized projection of the full ...

Pleco and Plectron -- Two Provably Secure Password Hashing Algorithms [PDF]
Proceedings of the 5th ACM Conference on Data and Application Security and Privacy, 2015 We propose two practical and provably secure password hashing algorithms, Pleco and Plectron. They are built upon well-understood cryptographic algorithms, and combine advantages of symmetric and asymmetric primitives. By employing the Rabin cryptosystem, we prove that the one-wayness of Pleco is at least as strong as the hard problem of integer ...

An online algorithm for generating fractal hash chains applied to digital chains of custody [PDF]
arXiv, 2007 This paper gives an online algorithm for generating Jakobsson's fractal hash chains. Our new algorithm compliments Jakobsson's fractal hash chain algorithm for preimage traversal since his algorithm assumes the entire hash chain is precomputed and a particular list of Ceiling(log n) hash elements or pebbles are saved.

Quantum security of subset cover problems [PDF]
arXiv, 2022 The subset cover problem for $k \geq 1$ hash functions, which can be seen as an extension of the collision problem, was introduced in 2002 by Reyzin and Reyzin to analyse the security of their hash-function based signature scheme HORS. The security of many hash-based signature schemes relies on this problem or a variant of this problem (e.g.

Sainsc: A Computational Tool for Segmentation‐Free Analysis of In Situ Capture Data
Small Methods, EarlyView.Spatially resolved transcriptomics methods can now profile the entire transcriptome, at full organism scale with nanometre resolution. Analysis frameworks that can efficiently and intuitively process the massive data generated by these methods are lacking.
