Dynamic Time Assisted Authentication Protocol (DTAAP) for Client-Server in WSN-IoT Environment

New expertise growths, such as the Internet of Things (IoT), Smartphones with multiple sensors, connected electronics, and smart sensors also taken out different utilities with new styles of service provider node and customer node (P-C) association criteria. Authentication is the very first step in creating customer-provider association. This work presents a secure and lightweight control key scheme named DTAAP. (Dynamic Time Assisted Authentication Protocol). DTAAP increases the reliability of protocols by utilizing time-based encryption keys and discards the security complication by offering reauthentication tickets. Therefore, it decreases the difficulty of digital signatures. The DTAAP is more scalable than other existing schemes.
