Cloud Computing's Improving Security with the Use of Quantum Cryptography Algorithms: Fortifying It Against New Cyber Dangers

Abstract

Although cloud computing has revolutionized data
storage and processing, it has also presented new security holes,
particularly in light of the imminent danger posed by quantum
computing. Although conventional cryptography is working for the
time being, quantum assaults might eventually break through. The
goal of this project is to create a cloud security architecture that is
resistant to quantum attacks by integrating lattice-based cryptography
with QKD protocols, namely the E91 protocol, for safe key
management. Further security against manipulation and unauthorised
access is provided by the framework's usage of quantum
authentication protocols, which improve user identity verification.
Scalability and efficiency in real-world cloud systems are guaranteed
by the suggested method, which strikes a compromise between strong
security and practical implementation. Results show that it
outperforms current approaches like DES and RSA with an
encryption time of around 30 milliseconds. This study helps meet the
present security concerns as well as the upcoming risks posed by
quantum computing by contributing to the establishment of
cryptographic standards that are future-proof. A robust defense
against ever-changing cyber threats, the framework fortifies cloudbased data security with the help of quantum physics. Findings from
this study pave the way for next-gen encryption methods that are
resistant to quantum computing, which bodes well for improvements
in cloud security.
