Blockchain-driven System for Authentication and Authorization

Security is really important when it comes to cloud computing services, and authentication and authorization are key to making sure no one can get in. We already have some traditional ways to access cloud services, but we also need to make sure no one else can get in cloud services. We have some traditional centralized access control models for the authentication and authorization which is third party based model which faces a critical challenge due to a high trust cost and a single point of failure. So for handling such type of challenges, Blockchain achieve the distributed trust for access control designs. Blockchain provides a dynamic update of access permissions by syncing the smart contract. To improve the storage efficiency and system scalability and to record a user’s access privileges only one transition is required. The system is up and running, the content of the smart contracts can be executed when trigger conditions are fulfilled, data is uploaded and network access is achieved, and processing is completed. The protocol combines the authentication and integrity properties of blockchain architectures suitable for power systems with the new blockchain technique to allow identity verification and source authorization in smart grid systems.
