OTP-Based Software-Defined Cloud Architecture for Secure Dynamic Routing

In the current era, anyone can freely access the Internet thanks to the development of information and communication technology. The cloud is attracting attention due to its ability to meet continuous user demands for resources. Additionally, Cloud is effective for systems with large data flow such as the Internet of Things (IoT) systems and Smart Cities. Nonetheless, the use of traditional networking technology in the cloud causes network traffic overload and network security problems. Therefore, the cloud requires efficient networking technology to solve the existing challenges. In this paper, we propose one-time password-based software-defined cloud architecture for secure dynamic routing to mitigating the above-mention issues. The proposed cloud architecture provides a secure data path through dynamic routing using One-Time Internet Protocol (OTIP) algorithm between each layer. On the network side, we use software-defined technology to provide efficient network management and data security. We introduce a software-defined cloud architecture that applies OTIP algorithms for secure dynamic routing. We conduct a comparative analysis between general IP communication and proposed OTIP communication architecture. It evaluates the performance of OTIP algorithms. Finally, we examine the proposed software-defined cloud architecture, including how to apply OTIP in secure dynamic routing according to the results of the comparative analysis.
