A Hybrid Encryption Technique for Data Sharing in Clouds

Abstract: Cloud computing has developed into the finest answer to space-related concerns for consumers as well as numerous IT Enterprises in today's modern world. Cloud computing has evolved as the ideal option. It's possible that the user may give some thought to the data's true privacy and its integrity. Utilising the many cryptographic approaches that are now available is one way to improve the data security provided by cloud computing. This study presented a hybrid cryptography strategy for security in cloud data storage based on Hash function and visual cryptography approach. In hash function, the user computes the hash value/hash digest of file and then uploads the file for storage to the cloud. The paper also offered a hybrid cryptography technique for security in cloud data storage based on visual cryptography approach. The data that is saved and encrypted on the cloud side of things. If the two hash values are identical to one another, this demonstrates that the data has not been tampered with in any way. MATLAB 8.3 is the programme that is used in order to carry out the simulation.
