A ROBUST LIGHTWEIGHT THREE-FACTOR AUTHENTICATION SCHEME FOR IOT IN A CLOUD COMPUTING ENVIRONMENT

Abstract

With the advancement of computer science and technology, the society pays more and more attention to the application of Internet of Things technology. The Internet of Things technology brings convenience to people's lives, but various security vulnerabilities in IoT devices still threaten people's privacy. We describe the occurrence process of these security flaws and propose a robust lightweight three-factor authentication scheme based on IoT in a cloud computing environment. Then we analyzed the security and performance of the proposed scheme.
