Abstract
Amidst the accelerating scenarios of cybersecurity and increasing concerns regarding data integrity organizations seriously seek strong and scalable frameworks as safeguard against sensitive data to keep it unmodified from illegitimate access. To ensure consistent performance and optimization in resource utilization over various types of devices security and scalability are of utmost requirements. Data integrity has become challenging issue in resource constrained devices as used in IoT. IoT has become one the major components in automation of healthcare, smart home and smart agriculture. This study proposes a DES based Scalable Hashing Algorithm (DESSHA) for smart devices using IoT. DESSHA due to its close alignment with theoretical values of all security test including sensitivity, confusion diffusion, uniform distribution and collision resistance with scalability. It provides message authentication for nearly all types of smart devices on IoT, especially for smart agriculture and E-Commerce purposes. Our analysis demonstrates that DESSHA provides a high level of security for message authentication for IoT enabled devices.
