Abstract The cloud customer is typically uninformed of the provider's threat assessment and mitigation procedures. Ask what safety precautions the service provider takes. So, the client must likewise do something to improve the supplier's security. The function of quantum key distribution (QKD) in cryptographic infrastructures is investigated in this work. QKD uses quantum mechanical systems to promise safe key agreements. There is a claim that QKD will play a significant role in upcoming cryptographic infrastructures. Without relying on computational assumptions, it can guarantee long-term confidentiality for encrypted data. In fact, even when using public-key authentication, we contend that QKD still provides stronger security than conventional key agreements. Several researchers have put forth various data recovery strategies, but they are ineffective and unreliable. When the primary cloud server loses its data and is unable to offer data to users, the proposed technique gives the user the option to acquire information from any backup server in order to achieve reliability. The decryption procedure is then carried out in response to the user's request. Experiments were done to demonstrate the applicability of the proposed frameworks, and performance indicators were compared to those utilized by other researchers. Based on this study, a framework is developed, that guarantees authentication and lays the way for safe data access, with better performance and fewer complications than the previous efforts.
