In the contemporary landscape of advanced technological ecosystems, the ubiquity of cloud computing serves as a cornerstone for orchestrating and maintaining a myriad of global datasets, information repositories, and service infrastructures. This widespread adoption of cloud computing, however, has brought forth a pressing need to confront and mitigate security challenges, necessitating the formulation of resilient protocols to safeguard the sanctity and confidentiality of data. In response to this imperative, our research endeavors to propose an innovative and secure paradigm for cloud data access, harnessing the synergies of attribute-based cryptography (ABC) and quantum key distribution (QKD). This methodology capitalizes on the intrinsic security of quantum channels to facilitate the secure transmission of cryptographic keys across nodes. We validate the effectiveness of our model through extensive simulations. This comparison, which is based on state-of-the-art methods, looks at a wide range of performance metrics, such as the time it takes to create a key, the time it takes to decrypt and encrypt, and other important factors. Compared to state-of-the-art algorithms, our proposed algorithm performs better with better encoding times (2.6s to 5.2s) and decryption timings (1.2s to 3.6s). While QKD-ABC regularly obtains the shortest analysis times (29.1s to 149.1s), it is clear that QKD-ABC is the best method for safe cloud data access. The particular numerical metrics demonstrate the unmatched performance of QKD-ABC in a variety of activities.
