Abstract

Given the advances in technology, resources such as quantum computing in the cloud have been increasingly used for studies and research. A practical example of this application is the first commercial quantum desktops, the SpinQ Gemini and the SpinQ Triangulum, which have the quantum computing feature in the cloud. In this context, IaaS (Infrastructure as a Service) platforms are applied to provide cloud computing. Thus, to ensure user security, confidentiality and data integrity, it is necessary to use security resources such as homomorphic encryption, which was proposed as a solution to the problem of maintaining the confidentiality of large volumes of data processed in cloud computing. The objective of this article is to demonstrate the functionality and security of IaaS platforms that use homomorphic encryption through an implementation made through the IBM Quantum platform, in the Qiskit language, and performing the Paillier algorithm.

Homomorphic encryption experiments on IBM’s cloud quantum computing platform

He-Liang Huang, Youwei Zhao, Tan Li +6 more

Quantum computing has undergone rapid development in recent years. Owing to limitations on scalability, personal quantum computers still seem slightly unrealistic in the near future. The first practical quantum computer for ordinary users is likely to be on the cloud. However, the adoption of cloud computing is possible only if security is ensured. Homomorphic encryption is a cryptographic protocol that allows computation to be performed on encrypted data without decrypting them, so it is well suited to cloud computing. Here, we first applied homomorphic encryption on IBM’s cloud quantum computer platform. In our experiments, we successfully implemented a quantum algorithm for linear equations while protecting our privacy. This demonstration opens a feasible path to the next stage of development of cloud quantum information technology.

Methods and Tools for Secure Quantum Clouds with a specific Case Study on Homomorphic Encryption

Aurelia Kusumastuti, Nikolay Tcholtchev, Philipp Lämmel +2 more

The rise of quantum computing/technology potentially introduces significant security challenges to cloud computing, necessitating quantum-resistant encryption strategies as well as protection schemes and methods for cloud infrastructures offering quantum computing time and services (i.e. quantum clouds). This research explores various options for securing quantum clouds and ensuring privacy, especially focussing on the integration of homomorphic encryption (HE) into Eclipse Qrisp, a high-level quantum computing framework, to enhance the security of quantum cloud platforms. The study addresses the technical feasibility of integrating HE with Qrisp, evaluates performance trade-offs, and assesses the potential impact on future quantum cloud architectures. The successful implementation and Qrisp integration of three post-quantum cryptographic (PQC) algorithms demonstrates the feasibility of integrating HE with quantum computing frameworks. The findings indicate that while the Quantum One-Time Pad (QOTP) offers simplicity and low overhead, other algorithms like Chen and Gentry-Sahai-Waters (GSW) present performance trade-offs in terms of runtime and memory consumption. The study results in an overall set of recommendations for securing quantum clouds, e.g. implementing HE at data storage and processing levels, developing Quantum Key Distribution (QKD), and enforcing stringent access control and authentication mechanisms as well as participating in PQC standardization efforts.

Quantum Cryptographic Protocols for Enhanced Cloud Security

Vinit Khetani

Quantum cryptographic protocols offer transformative potential for enhancing cloud security by leveraging the principles of quantum mechanics. These protocols ensure unbreakable encryption through quantum key distribution (QKD), where security is derived from the fundamental properties of quantum particles. Unlike classical encryption, which relies on computational complexity, quantum cryptography guarantees data protection by preventing unauthorized access, as any attempt to intercept quantum keys alters their state and can be immediately detected. This paper explores the application of quantum cryptographic protocols in securing cloud environments, addressing vulnerabilities posed by classical encryption techniques in the face of growing computational power. Key protocols, such as BB84 and E91, are analyzed for their potential in securing cloud infrastructure, offering enhanced confidentiality, integrity, and authentication of data. Additionally, this study highlights the integration of quantum cryptography with modern cloud architectures, overcoming challenges such as scalability and implementation cost. By employing quantum-resistant strategies, these protocols provide a robust defense against emerging threats from quantum computing, making them an essential solution for future-proof cloud security. The findings demonstrate that quantum cryptography, combined with advanced cloud security practices, can ensure secure, scalable, and resilient cloud infrastructures capable of protecting sensitive data in an increasingly interconnected digital landscape.

Quantum-Resistant Cryptography for Cloud Security

Mifta Mubashera, Faheem Babar, Seyed Ebrahim Hosseini +3 more

The increasing reliance on cloud storage across sectors has made the protection of sensitive data a critical concern especially as advances in quantum computing threaten to break traditional public-key cryptographic systems. This growing vulnerability raises urgent questions about how to secure digital assets in a post-quantum future. To address this challenge, this study aims to design, implement, and evaluate a hybrid encryption framework that combines symmetric encryption for data confidentiality with quantum-resistant public-key algorithms for key management and digital signatures. The objective was to develop a secure and practical solution that can be readily adopted using open-source tools. The system was built in a Linux-based virtual environment using an S3-compatible object storage platform, integrated with quantum-safe cryptographic libraries, and automated through scripting. Performance testing was conducted using files ranging from 100 MB to 1 GB, with metrics such as encryption and decryption time, CPU usage, upload/download latency, and internet throughput analyzed. The results showed that while quantum-safe operations added some overhead, even large files could be securely processed in under two minutes with stable system performance and no data corruption. These findings confirm that hybrid encryption models can be deployed today without specialized hardware, offering a forward-compatible and robust approach to cloud security. This work contributes a tested and reproducible framework for early adoption of quantum-safe cryptography in real-world cloud environments.

A Quantum-Cryptography-Enhanced Framework for Secure Cloud Computing Using Quantum Key Distribution (Qkd)

R. Jayachandran, D. Malathi

The widespread cryptographic methods RSA and AES have become more susceptible to quantum-based attacks because researchers developed quantum algorithms such as Shor's and Grover's. QKD chromosomes from quantum mechanics grant authorized parties the ability to exchange cryptographic keys securely alongside built-in eavesdropping detection functionality. In the proposed method a Quantum Key Distribution (QKD) is used to integrate into cloud environments to secure data against quantum threats which have become crucial security concerns today. A new security framework for combining QKD with standard cloud utilities strengthens both access privacy and verify data integrity and ensure authentication of user information. The system framework consists of key generation from quantum elements followed by distribution through quantum channels to support secure communication protocols for Software as a Service (SaaS) and Platform as a Service (PaaS) as well as Infrastructure as a Service (IaaS). The key performance evaluation of the QKD system includes measurements of key generation rate together with Quantum Bit Error Rate (QBER) and eavesdropping detection accuracy rates. The analysis against traditional cryptographic systems proves that QKD stands superior in quantum attack resilience. The proposed system demonstrates its efficiency and robustness through simulation outcomes as well as visual representations. The presented work demonstrates both the revolutionary capability of quantum technology for cloud security along with a deployable system architecture for future systems implementation. The research work advances the creation of cloud infrastructure systems which combine high security resilience to protect against future cyber threats.
