For both institutions and financial industry, once financial risk occurs, it will bring great harm. It is very necessary to forewarn financial risks before they occur. Through the analysis and supervision of financial risk can effectively control the occurrence of financial crisis. In the current Internet era, blockchain technology has been widely used in various aspects. In finance, in particular, blockchain has brought great convenience to the analysis and supervision of its risks. This paper aims to study financial risk analysis and related regulatory research through the relevant technologies of big data and blockchain. This paper puts forward the way of combining theory and model to study financial risk. The risk value is obtained through the study of risk‐related attributes. Experimental results show that the risk rate of financial risks under big data and blockchain technology has been reduced by 10%–15%. This degree of risk reduction is of great application in actual financial risk control. Financial security is closely related to financial risks and financial crises. Both risks and crises can be used to explain and measure the degree of security, and security can also be used to explain and measure risks and crises. The higher the degree of security, the lower the risk; conversely, the greater the risk, the lower the degree of security; a crisis is the result of a large‐scale accumulation of risks, and a crisis is serious insecurity, which is an extreme of financial security.","PeriodicalId":29939,"journal":{"name":"Security and Privacy","volume":"54 7","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50980464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Voice‐activated devices, by design, rely on personal voice biometrics for access‐level security, and insecure voice authentication techniques limit the development of voice interfaces that can deal with multiple users with different privileges. Furthermore, public concerns surrounding biometric systems have been reported. Outsourcing biometric data are liable to various privacy breaches, increasing vulnerability to cyberattacks from both criminal organizations and government agencies. In this article, we address the security and privacy challenges of voice authentication for IoT by presenting an edge‐based, hands‐free, single‐factor authentication scheme that consists of three security‐based features: random phrase verification, anti‐spoof verification, and text‐independent speaker recognition. The use of edge technology allows the integration of this authentication scheme with resource contained IoT devices such as voice assistants. Additionally, privacy is ensured by a novel security protocol that uses chaffing and encryption techniques to protect the users' biometric data stored locally on the edge device. Finally, the scheme does not compromise the user experience as it requires only two short voice inputs.","PeriodicalId":29939,"journal":{"name":"Security and Privacy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44459665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current statistics of the healthcare sector show that it is expanding at a remarkable rate. However, the performance of the healthcare system is impacted by many challenges, such as security, privacy, latency, scalability, and heterogeneity that come with advancement. Fog computing and software‐defined networks (SDN) are critical enabling technologies that help to improve IoT‐based healthcare systems by ensuring timely and reliable data provisioning for use in healthcare applications. SDN solves interoperability, device management, and network management issues and automates patient health monitoring without human interaction. SDN and fog computing in IoT‐based healthcare can optimize device communication and computing power at a low cost. SDN‐enabled fog computing has lower latency and better security than cloud‐based IoT healthcare architecture. The researchers have not entirely discovered SDN‐enabled fog computing to the best of our knowledge. This paper covers healthcare IoT technicalities and related technologies. We examined ways to merge SDN, fog computing, and IoT to improve healthcare solutions. Finally, we concluded the paper with research issues and future healthcare system improvements.","PeriodicalId":29939,"journal":{"name":"Security and Privacy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45531674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physical layer security techniques operate at the lowest stack of OSI layer against conventional cryptographic approaches, operating at the upper layer. However, techniques such as channel coding, power (directional antenna and artificial noise), and spread spectrum have been (and continuously) deployed to safeguard against sophisticated attacks. Most of these deployments are theoretical, and a few are enhanced for efficient security against an intruder. In this article, a boundary technique approach is proposed and applied to the physical layer to improve its secrecy‐capacity and subdue adversary effects at the legitimate receiver. Hybrid performance metrics were adopted, and a Monte Carlo simulation was performed. The result obtained using secrecy outage probability, secrecy‐capacity, and intercept‐probability show that our proposed techniques enhance the secret transmission between the main transmitter and legitimate receiver. The simulation results were compared with the analytical methods. It was found that the channel between the transmitter and the main receiver has a better signal‐to‐noise ratio than the corresponding eavesdropper's channel. Conclusively, performance of the proposed technique is validated for applications in emerging wireless communication systems.","PeriodicalId":29939,"journal":{"name":"Security and Privacy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44814256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are some key issues in the development of crowdsensing such as platform security and privacy protection. As the crowdsensing is usually managed by a centralized platform, centralized management will bring various security vulnerabilities and scalability issues. To solve these issues, an effective reputation‐based partition scheme (RSPC) is proposed in this article. The partition scheme calculates the optimal partition size by combining the node reputation value and divides the node into several disjoint partitions according to the node reputation value. By selecting the appropriate partition size, RSPC provides a mechanism to ensure that each partition is valid, as long as the maximum permissible threshold for the failed node is observed. At the same time, the RSPC reorganizes the network periodically to avoid partition attacks. In addition, for cross‐partition transactions, this paper innovatively proposes a four‐stage confirmation protocol to ensure the efficient and safe completion of cross‐partition transactions. Finally, experiments show that RSPC improves scalability, low latency, and high throughput for crowdsensing.","PeriodicalId":29939,"journal":{"name":"Security and Privacy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48550158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In modern day democracy, voting is one fundamental and most important tool for election. To strengthen this process, efforts must be made to achieve a confirmable and transparent voting system. Naturally, the veracity of the election process is of ultimate importance for the honor of the democracy itself. The online voting or e‐voting system is a cost‐effective procedure, which saves a lot of money and time spent for organizing the election. However, security, integrity of data and privacy of the voter are the increasing concerns in this context. In this paper, we have done a thorough literature survey of the various latest schemes in this context and found that the schemes prone to several security and privacy threats. Moreover, a major issue with all these schemes is that they are inefficient in terms of computation and communication overheads. With this motivation, we present a novel and efficient e‐voting scheme to tackle the security and privacy concerns. The proposed scheme is designed using the concept of blind signature, anonymous channel and trust worthy entities where elliptic curve cryptography (ECC) works as a backbone. The proposed scheme is formally evaluated using well known AVISPA simulation tool, which simulates the attack model using CL‐AtSe as well as OFMC backend according to Dolev‐Yao threat model. In both the cases, all the possible security threats are being nullified by the proposed scheme and results in safe communication. Also, the scheme is analyzed against all the possible attacks that jeopardize the integrity of the existing voting systems. Moreover, the proposed scheme is also compared with other prevailing schemes in terms of computation and communication overheads and found more efficient.","PeriodicalId":29939,"journal":{"name":"Security and Privacy","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48268240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
