In Mobile Cloud Computing (MCC), mobile user store their data in the remote cloud machine or storage without their personal control. The cloud computing services provide cost-effective storage spaces as well as easier ways to share information among various Mobile Cloud Computing entities. Everyone, including big corporate entities, wants to take advantage of cloud computing without compromising their data security. Therefore, data security and privacy are the major challenges for the data owner and cloud service provider. The control of stored data is not in the hands of the data owner, but before storing data over a cloud server storage, it should be properly encrypted so that any unauthorised user does not hack the data. Encryption is a process in which data is scrambled into unreadable contents, i.e. ciphertext, with the help of strong encryption keys. And with the help of the same encrypting keys, data can be descrambler easily by the authorised user. The Encryption strength depends on several factors, such as how keys are generated and which Key Management systems (KMS) are utilised, encryption algorithm implementation, use of hashing algorithm on stored data, and key size also mainly matter. Because of privacy concerns and various laws, the encrypting & decrypting keys can never be stored alongside data in the cloud storage. In this chapter, try to solve problems of data storage on cloud servers by fragmenting data into chunks and individual chunks get encrypted separately and using blockchain technology and its advanced security features to secure our uncontrolled data over cloud servers without 100 per cent control of the cloud service provider as well. Cybersecurity has become a critical factor in safeguarding sensitive data, due to the risk of various cyber threats, when the data is exchanged via third-party cellular or wireless networks. When the data from the mobile devices is stored on the mobile cloud computing (MCC) infrastructure, the MCC providers must enforce a robust and foolproof mechanism to protect the private and sensitive data from cyber attacks. Even though some of the existing literature suggests the use of blockchain to secure the data on the MCC, it lacks an address to the vulnerability that could still exist. Through this research, the author proposes a technical solution to enhance the security of user data stored on such cloud-based storage infrastructure. This work not only builds on the previous research findings but also provides practical mechanisms that can be adopted to safeguard sensitive data against emerging cyber threats.
