A Novel Mechanism for Design and Implementation of Confidentiality in Data for the Internet of Things with DES Technique

Confidentiality refers to the protection of data from unauthorised access. In other words, only those who have been granted permission to do so will have access to sensitive information. They are vulnerable to a variety of security threats, particularly when transferring data through IoT devices. As a result, we’re utilizing a DES Encryption Algorithm to encrypt data at the IoT transmitter and a DES Decryption Algorithm to decrypt it at the IoT receiver. We attain a level of data confidentiality by doing so. We’re utilising two BeagleBone Black boards as IoT transmitters and receivers, and we’re using IEEE 802.5 wired technology to communicate with each other. For developing DES Encryption and Decryption communication between these two BeagleBone Black boards serving as IoT devices, we’re employing the Client-Server technique. In both BeagleBone Black boards, we use the Debian operating system. The first BeagleBone Black board will act as an IoT transmitter, transmitting this encrypted message, while the second BeagleBone Black board will act as an IoT receiver, receiving the decrypted message and converting it to plain text.

I. Introduction

Effectiveness of information integrity depends on IoT device’s ability to handle authentic data and produce accurate output, which is required for the other phases of a system that depend on the output to function properly [17]. Confidentiality of data refers to the protection of information from unauthorised access. Access to sensitive information is restricted to those who have been given permission. IoT devices, in particular, are vulnerable to a variety of security threats. As a result, we encrypt data using the DES Encryption Algorithm at the transmitter and decrypt it using the DES Decryption Algorithm at the receiver. We attain a level of data confidentiality by doing so. AES algorithm can also be utilized for securing the transmission of data. Here in this paper, we use DES technique for implementing Confidentiality of data in the Internet of Things [18].
