Security in Opportunistic Sensor Network and IoT having Sensors using Light Weight Key Generation and Cryptographic Algorithm

Due to the vigorous constraint of resources in Opportunistic Sensor Network (OSN) and IoT having sensors and their applications in military and business raises demand to look out ways to secure the data in the sensors using cryptography. Cryptography is very ubiquitous in today's world; it is present in smart cards, your mobile phones and even in your Wi-Fi connection. Moreover not only programming language has some sort of support for encryption and decryption but this facility is also embedded in CPUs (ex-Intel AMD CPUs have support for AES encryption), sensors and smart cards. This paper is a successful attempt to use the existing AES for encryption and generating secret keys using lightweight key generation algorithm (Abstract)
