Abstract Internet of things (IoT) has already made its way into every industry and has started helping us in making smart decisions. Two billion people using the Internet at the moment and that is set to grow to probably 2 billion in the next couple of years and devices will be linked with themselves together using networks. Conventional cryptography uses a huge amount of energy which results in cost and complexity as compared to lightweight cryptography. Lightweight cryptography has been implemented to overcome conventional cryptography. In this paper, we have done a survey among different lightweight cryptographic algorithm protocol in aspects of RAM, efficiency, encryption and decryption cycles.

1 Introduction In this digital world, we can make everything talk to each other. The electronics objects that are connected to the Internet through their networks can exchange their data. Now billions and billions of objects are linked with the Internet. As these devices connected to each other will become the intelligent system and when they will exchange their data over the cloud they can transform our lives in a countless way whether it is in medical, house and so on. This results in consuming less cost and energy. IoT has brought evolution in this digital world by connecting to the Internet to extract meaningful information’s. M. Sinha (B) · S.

1.1 IoT Applications The IoT is changing much about the world we lived in. Wireless sensor and chips that are embedded in the physical objects exchanges their data over the Internet. In IoT, the devices interact, collaborate and share experiences with each other. The house has become a smart house, the electronic things within the house communicate with each other. Research shows that by the year 2020, 50 billion objects will be connected to the Internet [1]. Each person approximately will use 7.1 objects online. The IoT application is growing rapidly day by day [2]. Building electronics system using IoT is described in [3]. Most of the industries are showing their interest toward IoT. IoT applications in health care industries and improvement opportunities are discussed in [4] In every application, IoT demand has increased whether it has converted home to smart homes, agriculture, smart retailer, manufacturing, education and many more [5].
