Cloud-Block: An Integrated Cloud and Blockchain using Secure Cloud Computing

Cloud computing is a domain that provides data storage services using a cloud server. Cloud also provides data processing, security, and integrity. Recently, cloud service providers (CSP) have required high-end security for the data stored by cloud users. Every cloud computing company provides various services, including advanced secure cloud applications. This paper developed a model that provides enhanced security to cloud applications. The integration of blockchain into cloud storage data becomes more complex when designing the model. The blockchain is a technology that combines cloud data, divides the data into blocks, and forms a chain. The data is encrypted by using the Advanced Encryption Standard (AES) algorithm in every block of data by creating a unique ID, which can be accessed by authorized users. In this context, a high-end security model addresses the key challenges in combining the blockchain in cloud applications to process the uploaded data. Experimental results show the quantitative performance of various algorithms, and the proposed approach shows high performance in terms of cloud-based parameters.
