Internet of Things (IoT) is growing rapidly in different platforms and generates large number of data from each device. It is a challenging task to ensure the security of data as the IoT applications are dynamic in nature. We cannot rely on the third party (can be cloud severs) to ensure the security of the data. There can be different attack performed on the cloud or the third party can do any malicious activity to misuse the data of the owner. To overcome this, we can use blockchain-based technology named IOTA to ensure the data is secured and stored in the database and in the Tangle. The IOTA removes the third-party interaction from the transmission of data between the two parties. By using IOTA both the parties directly interact with each other. It also ensures that data is securely stored in the Tangle as it uses the SHA-256 to encrypt the data. It generates the hash of data which is stored, and once data stored, it can’t be changed as Tangle is immutable. Thus, by using blockchain-based technology with the IoT we can ensure data integrity, confidentiality and availability.
