Security in ZigBee Using Steganography for IoT Communications

ZigBee is an IEEE 802.15.4-sourced arrangement for a suite of high-level communication protocols employed to generate personal area networks. ZigBee is a less price, low-complex and low power consumption wireless personal area network (WPAN) norm that targets at the extensive developments of instruments and devices with prolonged battery life that are employed in wireless controls or applications that are used for monitoring purposes. It has an extensive utilization in industries and operations that are conducted physically. Hence, ZigBee is mostly correlated with IoT and M2M. Therefore, security in these WPANs becomes a major interest and has gained a good amount of notice currently. The security methods used in these networks over a period of time usually include practices that are cryptographic in nature. Then again these practices recommended till date can have good scopes of improvements, as a result, to turn up with additional assured and protected data communication. The chapter proposes a technique to enhance security in ZigBee using steganography over the secret data being communicated between communicating parties. However in cryptographic practices, the message even if it stands strongly resilient, can stimulate doubts and, therefore, could be adequate enough for a third party, spying the systems that something that are of significant use have been exposed. Hence, to keep the security features consistent in these networks this chapter proposes a technique to protect data by means of Steganography over the data to be communicated, this allows two communicating parties to transmit covert communication through a shared route in a way with the purpose, no adversary can even discover as in the covert communication is being transferred. Hence, making use of cryptographic practices helps protecting the insides of the messages only, on the other hand using steganographic practices can help in protecting the message contents and even the fact that a covert message has been transferred. The exclusive plan is to come up with a practice that is Steganographic in nature and ultimately has a resistance to any sort of steganalysis.
