Design and Evaluation of a Quantum-Resilient Cryptographic Framework for Enhancing Security and Efficiency in Distributed Cloud Environments
Samunnisa K, Sunil V.K. Gaddam, Madhavi K
Ssrg International Journal of Electrical and Electronics Engineering, 2024
- As the digital landscape evolves, the reliance on cloud computing for critical infrastructure across various sectors highlights the need for robust security mechanisms to protect sensitive data from emerging cyber threats, particularly those posed by quantum computing. Traditional cryptographic systems, while currently effective, are vulnerable to quantum attacks, necessitating the development of quantum-resistant solutions. This research introduces the Quantum-Resilient Cryptographic Framework (QRCF), a hybrid, adaptive cryptographic framework designed to safeguard cloud environments against both classical and quantum threats. The QRCF integrates lattice-based Kyber and code-based McEliece algorithms, offering a comprehensive and scalable solution for secure data storage, management, and transmission. Key contributions include the development of a dynamic security management layer that adapts to real-time threat analysis, ensuring continuous protection against evolving threats, and the implementation of robust post-quantum cryptographic methods that maintain high performance and low computational overhead. Quantitative analysis shows that the QRCF maintains a high throughput of 420 MB/s for encryption and 400 MB/s for decryption under normal operations, with latency as low as 3.2 ms and 3.6 ms, respectively. The framework exhibited strong resistance to various attack models, with success rates of 1.0% for brute-force attacks, 1.875% for MITM attacks, 0.833% for side-channel attacks, and 1.6% for replay attacks. Against quantum threats, the QRCF showed no vulnerability to Shor’s Algorithm and a minimal success rate of 0.667% for Grover’s Algorithm. The framework’s design ensures seamless integration with existing cloud infrastructures, providing practical migration strategies to quantum-safe cryptography without disrupting operational workflows. By addressing key research gaps in quantum-safe cloud security, this study contributes significantly to the field, offering a robust, scalable, and efficient cryptographic solution that enhances the security and operational performance of cloud environments in the face of advancing quantum computational capabilities.
Enhancing Cloud Security: A Hybrid Honeycomb-Lattice Encryption Model for Quantum Resistance
Samunnisa K, Sunil VK Gaddam, Madhavi K
Ssrg International Journal of Electronics and Communication Engineering, 2024
This study introduces an innovative Hybrid cryptographic model, which seamlessly integrates a honeycomb access mechanism with lattice-based encryption algorithms aimed at enhancing cloud security and addressing emerging quantum threats. The Hybrid model represents a significant leap forward from traditional Lattice encryption methods, as demonstrated by comprehensive simulations. It achieves a commendable success rate of 90.15%, boasting lower variability (1.72% standard deviation) compared to Lattice encryption’s 94.99% success rate with higher variability (2.93%). Operationally, the Hybrid model excels in providing consistent performance and faster processing times, making it a more efficient choice for cryptographic operations. Moreover, its cost-effectiveness is evident, with operational costs ranging from 0.862 to 7.24 microdollars for encryption and 0.871 to 7.29 microdollars for decryption. Furthermore, the energy consumption of both models is maintained within the practical range of 1.35 to 3.46 joules, highlighting the Hybrid model’s suitability. This research underscores the Hybrid model’s potential to safeguard cloud computing environments against advanced quantum attacks, offering a promising solution that strikes a balance between performance, cost-effectiveness, and energy efficiency. In an era where quantum computing poses a significant threat to traditional encryption, the Hybrid cryptographic model emerges as a robust and practical alternative, capable of fortifying cloud security while maintaining operational efficiency and affordability.

Cloud Computing (CC) is a very big field in the computer industry. It has systems that are connected through communication networks such as Internet. The LBA is an important cloud computing area to prevent overloaded workload and provide the same and valuable service. The various algorithms are used to solve the load balancing complexity. In this paper, we explain various standard load balancing techniques in different algorithms and challenges in assigning tasks to Cloud Computing.

International Journal of Innovative Technology and Exploring Engineering, 2019
We are in the information age there by collecting very huge volume of data from diverse sources in structured, unstructured and semi structured form ranging to petabytes to exabytes of data. Data is an asset as valuable knowledge and information is hidden in such massive volumes of data. Data analytics is required to have a deeper insights and identify fine grained patterns so as to make accurate predictions enabling the improvement of decision making. Extracting knowledge from data is done by data analytics, Machine learning forms the core of it. The increase in the dimensionality of data both in terms of number of tuples and also in terms of number of features poses several challenges to the machine learning algorithms . Preprocessing of data is done as a prior step to machine learning, so feature selection is done as a preprocessing step to have the dimensionality reduction of the data and thereby removing the irrelevant features and improving the efficiency and accuracy of a machine learning algorithm. In this paper we are studying various feature selection mechanisms and analyze them whether they can be adopted to sentiment analysis of big data.

Ant-based Integrated Traffic Control and Management in ATM Networks

Asynchronous transfer mode (ATM) is a cell-switching and multiplexing technology that combines the benefits of circuit switching with those of packet switching. Traffic management in ATM is concerned with ensuring that users get their desired quality of service (QoS). The problem of traffic management is especially difficult during the periods of heavy load particularly if the traffic demands cannot be predicted in advance. The issue of traffic control and bandwidth management in ATM-based networks is complex due to a mixture of different connection traffic types, QoS requirements, and time scales. In this paper, we provide an ant-based integrated technique to control the occurrence of congestion and allocate bandwidth for various traffic services in a prioritized manner. The forward ants collect the QoS information of the nodes regarding the available bandwidth and the buffer size. Then based on the QoS requirements of the various traffic classes, the optimum path is selected based on the observed QoS statistics collected by the ant agents. Therefore, the ant-based integrated technique provides the network to efficiently use the traffic, thus providing an efficient traffic management for the ATM network. By simulation results, we show that the proposed ant-based technique outperforms the existing architecture in terms of throughput and delay.
