A secure and robust information transit management technique for cloud in Collaborative Environment

Cloud computing has make revolution in dealing businesses store, process, and sharing data. However, ensuring secure and collaborative data management in clouds remains a significant challenge due to the risk of data breaches, unauthorized access, and privacy violations. Block-chain technology, with its decentralized and immutable ledger, has the power to handle these challenges by providing a reliable, secure and clear plan for data management. However, with the increasing amount of data being generated, traditional centralized cloud solutions are facing challenges related to scalability, security and cost. To address these challenges, a secure and robust information transit management technique for cloud is required specially for collaborative environment. This paper represents integration of blockchain mechanism with the traditional Cloud computing system. We represent a block-chain based technique for information transition and exchange securely with smart contracts and consensus mechanism. A scheme for securely sharing cryptographic keys between all participant. Further, for checking the validation of transaction and block a scheme have been designed. On the basis of Security analysis it has been observed that the proposed method is robust and also achieves wise performance with respect to communication overheads.
