An Overview on Security Issues In Internet Of Things

Internet of things has impacted 21st century like anything never before. Every device can be connected with each other via the internet. They can be remotely controlled or managed anytime. But all time connectivity of the IoT devices generates a huge amount of data which needs to be properly managed and disposed of as required. The data captured contains a large amount of sensitive information and patterns too; which can disclose behavioural or temporal activities. In this paper, we start by giving a brief introduction of IoT and then discuss some of its applications. After that security issues affecting IoT are discussed followed by a conclusion focusing on the need for small size & efficient cryptographic algorithms.
