The emergence of decentralized finance has transformed asset trading on the blockchain, making traditional financial instruments more accessible while also introducing a series of exploitative economic practices known as Maximal Extractable Value (MEV). Concurrently, decentralized finance has embraced rollup-based Layer-2 solutions to facilitate asset trading at reduced transaction costs compared to Layer-1 solutions such as Ethereum. However, rollups lack a public mempool like Ethereum, making the extraction of MEV more challenging. In this paper, we investigate the prevalence and impact of MEV on Ethereum and prominent rollups such as Arbitrum, Optimism, and zkSync over a nearly three-year period. Our analysis encompasses various metrics including volume, profits, costs, competition, and response time to MEV opportunities. We discover that MEV is widespread on rollups, with trading volume comparable to Ethereum. We also find that, although MEV costs are lower on rollups, profits are also significantly lower compared to Ethereum. Additionally, we examine the prevalence of sandwich attacks on rollups. While our findings did not detect any sandwiching activity on popular rollups, we did identify the potential for cross-layer sandwich attacks facilitated by transactions that are sent across rollups and Ethereum. Consequently, we propose and evaluate the feasibility of three novel attacks that exploit cross-layer transactions, revealing that attackers could have already earned approximately 2 million USD through cross-layer sandwich attacks.

Proxy signature scheme with certificateless and blind properties is called certificateless proxy blind signature (CT-PBS) scheme which holds many security properties such as unforgeability and delegation. This paper makes a security analysis on an improved CT-PBS scheme proposed recently and shows that the improved CT-PBS scheme yet does not solve the security drawbacks existing in original scheme. Four types of forgery attacks are presented: 1) The attacker (acts as a malicious Key Generation Center (KGC)) can imitate the selected original signer to authorize a selected proxy signer to get the signer right of the original signer without being known by the original signer;2) The malicious user can forge a proxy blind signature on any message by replacing the public key of the selected original signer and the public key the selected proxy signer;3) The attacker can authorize a selected proxy signer to get the signer right of the original signer A by replacing A's public key;4) The malicious original signer can forge proxy blind signature on any message by replacing the public key of the selected proxy signer. We also give an improved method on these security problems and a security analysis. © 2023 IEEE.

This paper presents a blockchain and AI-based methodology to prevent drug counterfeiting within the supply Chain. Incidents of counterfeit medicines, particularly in densely populated developing nations like India, have the potential to spiral into major disasters. This paper examines the effect of counterfeit medicine impacting the health & life of countless individuals. Additionally, it could also result in substantial financial and reputational repercussions for both governmental bodies and pharmaceutical companies. Thorough research and detailed investigation have shown substantial advantages to using blockchain technology over traditional systems. The traditional client-server centralized systems face significant complications concerning security and traceability. In contrast, the proposed blockchain-based architecture assures transparency and open-ness within the medicine supply chain. The architecture takes advantage by leveraging blockchain technology with respect to decentralization, tamper-proofing, and Traceability. Each product registered on the blockchain possesses a QR code for detailed information retrieval and ownership history, aiding in identifying counterfeit origins. Furthermore, each product also comes with authenticated certificates and lab reports. These reports are verified by drug administration authorities to strengthen the reliability of the product. As a result, developed system offers robust measures against counterfeit origins as compared to traditional and other blockchain based systems. © 2024 IEEE.

The air quality index (AQI) is a metric used to report air quality levels. There has been a substantial rise in the level of air pollution in Indian cities. Multiple methodologies exist for formulating a mathematical equation to ascertain the air quality index. Multiple studies have established a correlation between exposure to air pollution and negative health effects in the general population. The objective of this study is to determine the optimal approach for predicting AQI in order to aid in climate regulation. Nine separate Machine learning (ML) algorithms have been employed in the suggested study to ascertain the AQI. The use of the SMOTE algorithm in the datasets in ML resulted in improved accuracy when comparing the outcomes. Furthermore, all of the implementations have been thoroughly documented using graphs and metrics, which clearly illustrate the differences in outcomes and aid in identifying the specific factors that led to the improvement in accuracy. © 2024 IEEE.

The advancement of Internet technologies has led to growing security threats due to vulnerabilities in information systems. Various security solutions have been developed to counter these threats, but they often struggle to keep pace with increasingly sophisticated attack strategies. This study examines the effectiveness of a Cowrie honeypot system for analyzing SSH protocol attacks. By deploying Cowrie on a Raspberry Pi over 30 days, detailed data on attacker behavior was gathered. Key findings reveal the predominance of SSH over Telnet attacks, frequent targeting of weak passwords, and a geographic concentration of attacks from China, India, and Australia. This study underscores the need for robust password policies and user education to reduce vulner- abilities. Cowrie proved valuable in capturing compre- hensive logs and providing critical insights into attacker strategies, highlighting the importance of incorporating honeypots into cybersecurity infrastructure. © 2024 IEEE.

The advent of electronic voting (e-voting) systems has promised greater accessibility, efficiency, and transparency in the process of electoral. However, by adopting e-voting systems, they bring forth significant challenges, primarily related to security and scalability. Old e-voting systems encounter threats such as vote manipulation and denial-of-service attacks, making it imperative to design robust and secure solutions. This research focuses on addressing these challenges through a collaborative approach utilizing sharding technology with interoperability enabling it to handle a vast number of votes simultaneously without compromising performance or security. Recognizing the importance of seamless data exchange, our e-voting system places a strong emphasis on interoperability. The consensus mechanism providing rapid transaction finality, enhanced security, and resilience against malicious actors. It ensures the integrity in the process of voting and safeguards against alterations. We present a pioneering approach to reduce all kind of challenges in existing model by giving a secure e-voting that harnesses the power of sharding blockchain, interoperability, and a novel consensus mechanism. The analysis of blockchain structure that provide blockchain as a service initiates the article. Then, based on blockchain technology, we suggest a unique electronic voting method. That resolves all the issues we found. This reduces the cost of holding a national poll and enhances security. © 2024 IEEE.
