HERFA: A Homomorphic encryption-Based Root-Finding Algorithm

IEEE Embedded Systems Letters 2024年

作者： Bencini, Christopher Mendola, Jason He, Wei Kim, Sunwoong Rochester Institute of Technology Department of Electrical and Microelectronic Engineering RochesterNY14623 United States

Edge-cloud computing architectures are exposed to significant security challenges. Although general encryption methods can mitigate some of these concerns, they require decryption to perform operations on data, exposing the data and secret keys to potential attacks. Homomorphic encryption (HE), which allows operations on encrypted data without decryption, provides an effective solution to this issue. HE-based root-finding algorithms can expand the use of HE to a wider range of real-world applications that involve solving equations. This letter presents an adaptation of the well-known Newton's method for use in the HE domain. Specifically, it employs a division-free approach to remove the division operation, which is not a basic HE operation. In addition, the proposed method is extended to handle a polynomial multiplicity greater than one for faster convergence. Compared to an alternative implementation that uses a numerical method for division, the proposed HE-based root-finding algorithm (HERFA) significantly reduces the number of sequential multiplications, which is a key factor limiting the feasibility of applications in the HE domain. This reduction allows HERFA to achieve faster execution speeds or higher accuracy. © 2009-2012 IEEE.

As the widespread application of multimedia communication technology, information transmission security has become increasingly important. The multi-scroll chaotic system exhibits complex dynamic behavior, and it is usually used to the design of encryption algorithm for image and video information by the sensitivity of initial values. The chaotic systems with multiple scrolls are investigated by a transformation method of nth order complex polynomial, and two examples of chaotic systems with four and six scrolls are given by the chaos anticontrol theory, respectively. Based on the chaotic system with six scrolls, a simple encryption algorithm is designed for image information by scrambling and confusing operations. A hash sequence generated from the original information is given to obtain the initial keys, and three pseudo-random sequences are designed through the operations of multiplication and modulo. Furthermore, the security analysis is discussed by key space and correlation coefficient, etc. The presented encryption method exists a large key space, and it can resist to common attacks, such as differential attack, crop attack and noise attack. The practicality and effectiveness are verified by the encryption experiments of image information in the end. © (2024), (International Association of Engineers). All Rights Reserved.

Advanced smart grid applications such as wide-area monitoring, protection, and control (WAMPAC), considerably depend on the synchrophasor measurements gathered from different locations of the power grid. These timestamped measurements are provided by Phasor measurement units (PMUs) and phasor data concentrators (PDCs). These devices are optimally deployed at selected nodes in the grid. PMUs and substation PDCs are routable protocol-based network devices and comply with the IEEE C37.118 standard. Since the PMUs generally communicate through a public wide area network, they are vulnerable to cyberattacks. As a result, these vulnerabilities lead to compromised data integrity, confidentiality, and availability of the smart grid. To cover the cybersecurity vulnerabilities in synchrophasor communication and achieve compatibility between the data transfer based on IEEE C37.118.2 with IEC 61850 standard, IEC 61850-90-5 was released. This part of the standard includes security measures to achieve authentication, integrity, and confidentiality if required. In this work, we implemented publisher and subscriber libraries capable of routing secure GOOSE messages while respecting the time delay specifications set by the IEC61850 standard. The performance of encryption and authentication algorithms was assessed and experimentally verified. In addition, the proposed framework's robustness against cyber-attacks was evaluated.

Cloud Computing is an emerging paradigm which has become today's hottest research area due to its ability to reduce the costs associated with computing. Cloud computing is most interesting and enticing technology which is offering the services to its users on demand over the internet. Since Cloud Computing stores the data and disseminated resources in the open environment, security has become the main obstacle which is hampering the deployment of Cloud environments. Even though the Cloud Computing is promising and efficient, there are many challenges for data security as there is no vicinity of the data for the Cloud user. The main scope of this paper is to solve the security issues in both cloud providers and cloud consumers. The outcome of the research paper is securing cloud data storage by using modulo 37, but existing hill cipher working with modulo 26.

Cloud computing is a technology that facilitates numerous configurable resources in which the data is stored and managed in a decentralized manner. However, since the data is out of the owner's control, concerns have arisen regarding data confidentiality. encryption techniques have previously been proposed to provide users with confidentiality in terms of outsource storage;however, many of these encryption algorithms are weak, enabling data security to be breached simply by compromising an algorithm. We propose a combination of encryption algorithms and a distribution system to improve database confidentiality. This scheme distributes the database across the clouds based on the level of security that is provided by the encryption algorithms utilized. We analyzed our scheme by designing and conducting experiments and by comparing our scheme with existing solutions. The results demonstrate that our scheme offers a highly secure approach that provides users with data confidentiality and provides acceptable overhead performance.

The Internet of Things (IoT) is a two-decade-old technology that allows the interconnection of various cyber-physical objects located anywhere in the world over the internet. A cyber-physical object is an inanimate object with the ability to connect itself to the internet and communicate with other similar objects. This communication is enabled by communication protocols that bridge the gap between hardware devices and the user by ensuring secure communication with optimum efficiency. As the number of IoT devices is increasing exponentially every year with the current estimation of more than 35 billion IoT devices according to a study conducted by ***, there is a need for a lightweight and highly secure communication protocol for IoT devices. This creates a need for handling all the dynamic data exchanges in real-time. Hence, Big Data and IoT technologies are often proposed together for processing and analyzing data streams. Incorporating Big Data analytics in IoT applications enables real-time information transfer, data monitoring and processing easily. To facilitate efficient communication in IoT networks, the Routing Protocol for Low-Power and Lossy Networks (RPL) comes into the picture which is a low power consuming routing protocol that operates on IEEE 802.15. This paper aims to encrypt the RPL Protocol using cryptographic algorithms and compare the results with a non-encrypted RPL Protocol using Cooja Simulator so that the data is securely communicated for Big Data analysis. The (Secure Hash Algorithm) SHA3 algorithm had been used to encrypt the sink nodes of the RPL protocol and the parameters such as average power consumption, network graph, latency is analyzed and compared. The results of this experiment show a considerable drop in latency and power consumption after deploying cryptographic encryption.

In 2023, Basso, Maino, and Pope proposed FESTA (Fast encryption from Supersingular Torsion Attacks), an isogeny-based public-key encryption (PKE) protocol that uses the SIDH attack for decryption. In the same paper, they proposed parameters for that protocol, but the parameters require high-degree isogeny computations. In this paper, we introduce QFESTA (Quaternion Fast Encapsulation from Supersingular Torsion Attacks), a new variant of FESTA that works with better parameters using quaternion algebras and achieves IND-CCA security under QROM. To realize our protocol, we construct a new algorithm to compute an isogeny of non-smooth degree using quaternion algebras and the SIDH attack. Our protocol relies solely on (2, 2)-isogeny and 3-isogeny computations, promising a substantial reduction in computational costs. In addition, our protocol has significantly smaller data sizes for public keys and ciphertexts, approximately half size of the original FESTA.

Cloud generally relates to storing, processing and managing of data over a network. The cloud provides mainly three services, storage as a service, platform as a service and software as a service using internet, based on the user's demand. As it became a vital platform, many companies are building their infrastructure. This has increased the corresponding vulnerabilities and threats as these services are often provided by third parties. So, security of the information in the cloud is a noteworthy issue for the cloud client. On the other hand, Performance of the security-based algorithms is another major concern. So, the work plan is to analyze the efficiency of these algorithms, based on the encryption time, decryption time, encryption throughput and memory utilized for encryption by the algorithms for different sizes of file formats like text, image and video. Further, eliminating the privacy concerns of data stored in cloud by enhancing the security using encryption algorithms like DES,3DES,AES and BLOWFISH.
