Problems and prospects in internet of things (IoT)security threats

Internet of things is a popular technology which is growing at a faster pace day by day. the internet of things (IoT) describes physical objects (or groups of such objects) that are embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems over the internet or other communications networks. the important concerns in the data security of IoT applications are insecure communications and data storage. one of the significant challenges for IoT security is that compromised devices can be used to access confidential data. cryptography is an efficient way to deal with this challenge. encryption is a fundamental form of defense that deals with security of the data itself. this means that even in the event of a system breach, compromised data is still only readable by authorized users in possession of the right encryption keys. it's an efficient solution against eavesdropping attacks (used in industrial espionage), also known as sniffing attacks, when the cybercriminal passively accesses data as it is being sent or received on the network. cryptography is also a good defense against active eavesdropping (aka man-in-the-middle attack) in which the hacker intercepts all relevant messages and injects new ones between two devices. this paper contains of comparison of various models and framework & algorithms used in earlier research with respect to IoT security issues. our future proceedings can be in the direction to develop a novel approach to ensure security for IoT using efficient cryptographic algorithms.
