Privacy and Security in IoT Middleware for Critical Applications

Abstract

IoT middleware is an extra layer that sits between cloud apps and IoT devices, cutting down on cloud processing and data handling. Middleware primarily uses IoT gateways to connect to various IoT devices in a typical IoT system model. The emergence of novel IoT applications on cloud platforms has resulted in fresh risks to data security and privacy. IoT system security is regarded as a significant development. It is found in numerous appliances, including electronic voting, healthcare, and industrial uses. Cryptography as well as Steganography are used to stop hackers from reading covert information, where steganography is found to be most effective for programs designed to keep attackers from discovering who transmitting confidential information. The purpose of this paper is to suggest a new steganography algorithm. The morse code algorithm is the newly suggested steganography algorithm. This algorithm consists of encryption, hiding and decryption. The performance of security of proposed algorithm for iot middleware is found better as compared to existing systems.
