Securing IoT Data in the Cloud with Blockchain Technology

Preserving privacy and integrity is one of the important needs of any internet based platform especially if it is based on cloud. Block chain has been a recent technology key player in securing cloud based platforms. In the proposed work, we have used Blockchain technologies to provide encryption for cloud IoT results. Blockchain has recently become a promising software for cloud cluster integration and enhancement of cloud transaction protection and access to data and application codes. The main objective is to use blockchain technology to encrypt heterogeneous and enormous data. Authorizing the data obtained from different sources. Furthermore, more stable and better hash functions, such as SHA-256, SHA-384, and MD5 are now available, a future attacker would require more time to produce all available SHA512 hashes to brute force a hashed password from your database from a security standpoint. As a result, we consider SHA512 to be more robust and reliable in terms of the time it takes to compute a single hash when opposed to all other hash functions. As a result, we have introduced modified SHA512 in the proposed work for added reliability
