While Certificate Transparency (CT) improves server certificate credibility, CT log servers remain vulnerable, risking data integrity and trust. This paper proposes the Append-only Authenticated Data Sets (AADS) model, which enhances cloud computing security by supporting append-only properties and fork consistency in transparent logs, preventing malicious modifications and preserving divergent log views. Formally defined using RSA accumulators, the model includes efficient algorithms for initialization, data addition, search, and evidence verification, ensuring security under strong RSA and adaptive root assumptions while reducing space complexity. Additionally, Append-only Authenticated Dictionaries (AAD) offer better space and communication efficiency. A prototype transparent log system demonstrates how these structures mitigate identity authentication risks caused by missing append-only features and fork consistency. Key challenges remain, including scalability, cryptographic weaknesses, and coordinated attacks by compromised log servers and malicious entities.</div></div>","PeriodicalId":50635,"journal":{"name":"Computer Standards & Interfaces","volume":"93 ","pages":"Article 103978"},"PeriodicalIF":4.1,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143377471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on hyperchaotic sequences generated by the FO 4D hyperchaotic system, exclusive-or (XOR) operations, and permutation the S-box is constructed. A comprehensive evaluation based on various algebraic criteria demonstrates that the proposed S-box exhibits favorable performance in terms of strict avalanche criterion (SAC), differential approximation probability (DP), nonlinearity (NL), bit independence criterion (BIC), linear approximation probability (LP), fixed point (FP), reverse fixed point (FPr), and correlation immunity (CI). The proposed S-box exhibits excellent NL of 112, comparable to that of the Advanced Encryption Standard (AES) S-box. Furthermore, a novel color image encryption technique is developed to ensure the privacy of color images. The proposed color image encryption algorithm combines Arnold Cat map (ACM), a high-performance generated S-box, Rivest–Shamir–Adleman (RSA) algorithm with 2D Henon chaotic map (HCM). Through rigorous testing, analysis, and comparison with recently reported image encryption algorithms, the suggested algorithm demonstrates its security, efficiency, and resistance to different standard attacks.

Metaheuristic algorithms (MHAs) have recently emerged as robust alternatives for optimizing MLP training, yet no current package offers a comprehensive, standardized framework for MHA-MLP hybrid models. This paper introduces MetaPerceptron, an standardized open-source Python framework designed to integrate MHAs with MLPs seamlessly, supporting both regression and classification tasks.

By offering over 200 MHAs, MetaPerceptron empowers users to experiment across a broad array of metaheuristic optimization techniques without reimplementation.

It is built upon a chameleon authentication tree (CAT) and digital signatures. That is, a user may confirm the retrieved data item’s integrity by recomputing the hash value on its underlying CAT root and further checking a signature of this value created by the data owner. However, many lightweight application scenarios may not deploy public-key infrastructure (PKI) to support the digital signatures. Moreover, in frequently updated application scenarios such as trend analysis and stock forecasting, many new digital signatures are generated, and malicious cloud servers might return old versions of a queried outsourced data item and the corresponding signature. Consequently, maintaining those previously created signatures becomes a challenge. In this paper, to overcome these issues, we put forth a novel construction framework of VDS by introducing a redactable blockchain. Specifically, we treat the root value of the CAT as a transaction and package it to a redactable blockchain. After that, the immutability of the underlying redactable blockchain ensures the integrity of outsourced data streaming and avoids using the digital signature. Also, as the data is updated, we can update the root value of the CAT by re-editing the corresponding block. We also put a concrete VDS construction in the new framework, and formally prove its security. Theoretical compression and experimental results indicate that the proposed VDS protocol has merits in functionality and practicality.</div></div>","PeriodicalId":50635,"journal":{"name":"Computer Standards & Interfaces","volume":"93 ","pages":"Article 103972"},"PeriodicalIF":4.1,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143169386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a secret image-sharing scheme with distributed authentication (DWTAT-DASIS) designed for cloud storage environments.

Finally, security analysis and experiments were conducted on the proposed protocol, demonstrating its ability to resist common attack methods as well as some deeper-level attack methods, meeting the security requirements for image storage in cloud systems.
