Review of Different Encryptionand Decryption Techniques Used for Security and Privacy of IoT in Different Applications

Internet of Things (IoT) allows different devices connected to global network or Internet for desired application. This emerging trend of Internet of Things have been developing with exponential rate since last two decades and where different technologies and protocol stacks have been introduced in market. While developing different techniques of integration of smart devices we are facing security and privacy issues of data. To cope up with these issues different techniques have been introduced to overcome this problem. In this research paper we provide the survey of different techniques and technologies used to provide reliable and secure data communications. This research paper will focus on encryption and decryption techniques used in IoT.
