Research ArticleOpen accessIn the keywordsQuantum-Enhanced IoT-Cloud Security: Integrating SHAP and Variational Quantum ClassifiersVeena Antony, Nainan ThangarasuIn the current Internet era, there are now trillions of gadgets online, and the Internet of Things is becoming a necessary part of daily life. IoT devices are connected, but this also makes them vulnerable to cyberattacks. Cyberattacks targeting Internet of Things (IoT) systems have increased dramatically in both volume and sophistication in the last year. Determining the importance and … …Journal of Computer Science, Vol. 21, Issue 1 · 20 Dec 2024 · 4,951 accessesView PDFCite
Review ArticleOpen accessIn the keywordsMitigating Privacy and Security Risks in the Era of Big Data: A Comprehensive Framework of Best Practices and ProtocolsUma Narayanan, Nithin Puthiya Veettil, Ratheesh Thottungal Krishnankutty et al.Addressing the intricate challenges of security and privacy in big data necessitates a focused research approach toward the development of innovative frameworks, protocols and algorithms. This study advocates for a heightened focus on advancing encryption technologies and methodologies to bolster data anonymization, thereby fortifying the protection of user information. Additionally, emphasis is placed on enhancing data access control mechanisms to … …Journal of Computer Science, Vol. 20, Issue 9 · 13 Jul 2024 · 5,585 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSegmented Block Cipher Algorithm Based on ASCII-Codes ManeuverShadi Rasheed Masadeh, Hamza Abbass Al-SewadiDue to their complexity, computation time and power requirement, the secure and widely used cryptographic systems such as 3DES and AES may not be considered suitable for applications like mobile and remote sensing of sensitive data. Therefore, secure but less complicated algorithms for data encryption are still sought. This paper suggests a new Segmented Block Cipher Algorithm (SBCA) is a … …Journal of Computer Science, Vol. 13, Issue 12 · 15 Dec 2017 · 6,899 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCarving Secret Messages out of Public InformationNaya Nagy, Marius Nagy, Selim G. AklThis study shows that secret information can be shared or passed from a sender to a receiver even if not encoded in a secret message. In the protocol designed in this study, no parts of the original secret information ever travel via communication channels between the source and the destination, no encoding/decoding key is ever used. The two communicating partners, … …Journal of Computer Science, Vol. 11, Issue 1 · 25 Feb 2015 · 8,037 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA MODIFIED ELLIPTIC CURVE DIGITAL SIGNATURE ALGORITHM FOR PUBLIC VERIFIABILITY WITH DATA DYNAMICS IN CLOUD COMPUTINGD. Sumathi, Ramachandra V. PujeriCloud storage is considered to be the most critical factor in decision making for users as it largely scales down the infrastructure in terms of size, cost and design. Considering factors such as local storage cost, maintenance a single server model can support multiple users on a needed basis. This raises concerns for integrity verification i.e., assuring the correctness of … …Journal of Computer Science, Vol. 10, Issue 10 · 28 Jun 2014 · 6,486 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA NOVEL APPROACH FOR INFORMATION SECURITY IN AD HOC NETWORKS THROUGH SECURE KEY MANAGEMENTS. Suma Christal Mary, M. PallikondaRajasekaran, Y. ChrisbinJeevaAd hoc networks provide flexible and adaptive networks with no fixed infrastructure and dynamic topology. Owe to the vulnerability nature of ad hoc network, there are lots of security threats that diminish the development of ad hoc networks. Therefore, to provide security for information of users and to preserve their privacy, it becomes mandatory to use cryptographic techniques to set … …Journal of Computer Science, Vol. 9, Issue 11 · 2 Oct 2013 · 6,690 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnhancing Security in E-Health Communications using Multi-Agent SystemRossilawati Sulaiman, Dharmendra Sharma, Wanli Ma, Dat TranProblem statement: In this study, we address the security needs in online communications, specifically in the e-health domain. We focus on how to provide different security strengths to different types of communications in e-health, where each communication transmits different types of information with different levels of sensitivity. Approach: The Multi-Agent System (MAS) approach is used to develop an agent-based system … …Journal of Computer Science, Vol. 8, Issue 5 · 17 Feb 2012 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA New Security Model using Multilayer Approach for E-Health ServicesRossilawati Sulaiman, Dharmendra Sharma, Wanli Ma, Dat TranProblem statement: Delivering services online is important in e-health. Services that are delivered through online communications between engaging parties, often involve sensitive information transmitted over the Internet. However, while the Internet successfully facilitates these services, significant threats also come in parallel. Network attacks, information breaches and malicious software on a computer system are common threats to the Internet. These threats … …Journal of Computer Science, Vol. 7, Issue 11 · 29 Aug 2011 · 6,822 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Secure Routing Protocol to Eliminate Integrity, Authentication and Sleep Deprivation Based Threats in Mobile Ad hoc NetworkEdna Elizabeth Nallathambi, Radha Sankararajan, Vaithiyanathan Sundaram, Gracelin SheebaProblem statement: Network security in Mobile Ad hoc Network (MANET) is a major issue. Some of the attacks such as modification, impersonation, Time To Live (TTL) and sleep deprivation are due to misbehaviour of malicious nodes, which disrupts the transmission. Some of the existing security protocols such as ARAN, SAODV and SEAD are basically used to detect and eliminate one … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAccelerated Search for Gaussian Generator Based on Triple Prime IntegersBoris S. Verkhovsky, Md Shiblee SadikProblem statement: Modern cryptographic algorithms are based on complexity of two problems: Integer factorization of real integers and a Discrete Logarithm Problem (DLP). Approach: The latter problem is even more complicated in the domain of complex integers, where Public Key Cryptosystems (PKC) had an advantage over analogous encryption-decryption protocols in arithmetic of real integers modulo p: The former PKC have … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,517 accessesView PDFCite
