Summary: Covalent organic frameworks (COFs) have shown potential as membrane materials for water purification and organic solvent nanofiltration due to their adjustable pore size and ease of functionalisation. However, current COF membranes are limited in their mechanical stability and structural integrity when applied on flexible polymeric substrates. In this study, COF-LZU1 membranes were fabricated on pre-designed ceramic hollow fibres using direct interfacial polymerisation, resulting in highly crystalline and defect-free COF layers. The membranes exhibited high pure water permeance and rejection rates for dyes, highlighting their potential for enhanced process intensification.

Summary: This article discusses the locally-APN power functions introduced by Blondeau, Canteaut, and Charpin, which generalize APN functions and are potentially more resistant to differential attacks. The study focuses on the Niho type power function F(x) = xs(2m- 1)+1 over the finite field F22m, where s is the multiplicative inverse modulo 2m + 1. The authors prove the locally-APN property of F(x) and determine its differential spectrum through detailed analysis of equation solutions in finite fields. The article highlights that computer experiments confirm the coverage of all Niho type locally-APN power functions for 2 <= m <= 10. Additionally, the boomerang spectrum of F(x) is determined by using its differential spectrum.

Summary: As reputation evaluation systems become popular on Internet service platforms, there is a growing concern about the presence of malicious merchants who try to disrupt the market environment through unfair practices. To protect the privacy of evaluators and ensure fairness in the evaluation system, this paper proposes an identity-based dynamic group signature scheme for reputation evaluation systems. The scheme allows group members to sign messages anonymously in the name of the group, and the group manager can identify the actual signer in case of disputes. The proposed scheme is secure, efficient, and meets the complex application requirements.

Summary: The Industrial Internet of Things (IIoT) utilizes physical devices to collect data, which needs to be saved on a cloud server for processing and analysis. Traditional encryption techniques make it difficult to search the generated ciphertext. Public-key encryption with keyword search (PEKS) can provide data encryption and confidential searching, but it is susceptible to internal keyword guessing attacks (IKGAs) due to limited commonly used keywords. A user-friendly public-key authenticated encryption with keyword search (PAEKS) scheme is proposed in this article to address this issue.

Summary: The anonymous credential has various applications, such as pay-as-you-go strategy in electronic subscription. However, the strategy may not suit non-regular users as they require stricter identity supervision. Identity supervision is a crucial part of an anonymous credential system and needs to be both reasonable and practical in regulating user behavior. The combination of customized k-times and epochs is necessary due to the limitations of existing works. This paper presents a permissioned redactable credentials scheme that allows fine-grained supervision, user control, and user redaction, providing potential utility when evaluated for performance.
