Blockchain-Based User Authentication in Cloud Governance Model

Evolution of digital communication has facilitated human beings to avail electronic services at their doorsteps. User can overcome the compulsion of their physical presence for accessing any type of service and hence can perform multiple tasks while availing electronic services within the same time frame. Furthermore, the present situation of global pandemic of corona virus (COVID19) has shown the necessity of electronic communication, so as to maintain the rules of social distancing to prevent transmission of virus within our society. In this entire process, utmost focus should be given over security of sensitive information which are transmitted through open digital medium (like Cloud). Advanced security schemes like Blockchains may be used to ensure digital identity of users. This task becomes more compact if an integrated environment can be designed for deployment, monitoring, and maintenance of multifaceted electronic services in a secured and Citizen centric manner. In this case, a multivariate smart card will act as a single window interface between the Citizen and Government for transmission of SERVICE REQUEST and SERVICE RESPONSE, respectively. The application of Blockchain within this integrated electronic service delivery model will build trust among the end users. To achieve this objective, authors have proposed Blockchain-based user authentication scheme during Citizen to Government (C2G) type of Cloud Governance transaction. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
