IoT Node-Node Secure Communication Using RIPEMD-128 and DES

Internet of things (IoT) is believed to be the greatest thing that came along with the birth of the internet 4.0. IoT security is a growing concern that have received a lot of research interest in recent times. IoT security covers these four critical areas: Device or hardware, Communications, Cloud, and Life cycle management. At each level of these security protocols are breaches that continue to threaten the continuous adoption and use of this pervasive technology that homes, organizations and Governments use towards collecting, analysing and decision making in most cases. The concept of Internet of Things-IoT describes the environment where devices connect with each other to communicate, collect, store sensor data to the cloud. The sensor data is then processed and analyzed towards describing valuable information. IoT solutions support domestic, industrial, and Governmental installations for the monitoring of environmental data, health monitoring, control and management of household appliances, weather recording and forecasting, and the like. Loosely speaking, Internet of Things - IoT concerns itself with the interconnectedness of embedded devices and the internet for the purpose of collecting, recording, analyzing and sharing of sensor data using sensors, actuators, and Radio frequency Identifiers - RFID. The Race Integrity Primitive Evaluation Message Digest (RIPEMD 128) and Data Encryption Standards (DES) were used to achieve the ultimate goal of providing improved security for end-end encryption for secured communications within IoT systems. The authors proposed a combined approach with the use of a cryptographic algorithm and a hash function to increase security for IoT node-node communications.
