Published Paper Details:

Internet of Things (IoT) is a network of physical devices like vehicles, home appliances and other items embedded with electronics, software, sensors, actuators and connectivity which allows these devices to connect and transfer data. This allows the efficient and smart solutions for communicating with the heterogeneous devices. Thus, IoT opens up the key issues such as bandwidth, security, power, privacy and scalability. Among these, the Security and Privacy are main concerns or vital elements that need to be addressed to perform secure data exchange among devices in IoT. The current solutions for security at each layer are still vulnerable for attacks. This paper encloses the comparative analysis of various lightweight cryptographic algorithms used as solutions for IoT security issues. The paper also provides the brief study of algorithms with various possible attacks and more security issues that can occur in IoT environment. At last, paper encloses various opportunities and challenges based on the IoT security lightweight cryptographic solutions
