Exponential rise of wireless transmission and internet technologies has broadens the horizon of communication systems engrossing multitude of applications and service domains. Wireless Sensor Network (WSN) being the native communication paradigm employs multiple sensor nodes cooperatively operating together. Enabling Quality-of-Service (QoS) in IoT system inevitably requires secure data transmission and resource access. WSN being distributed network with multiple sensor nodes requires optimal data security to facilitate secure and QoS sensitive communication. In major existing systems, the focus is made on employing classical cryptosystem or single layer security features that often possess vulnerability of getting attacked or breached. Classical approaches like public key cryptosystems; biometric features based standalone security systems etc are confined to meet optimal security provision. On the other hand, majority of existing approaches imposes huge computational overheads during key management and encryption-decryption that eventually forces nodes to undergo energy exhaustion thus affecting QoS provision. In this case, it is imperative and significant to develop a lightweight and robust security model for WSN enabled systems. To meet this demand, in this paper developed enhanced RSA-assisted Elliptic Curve Cryptography (ECC), Bio-hash and time stamping methods. Bio-hash developed to perform user verification at the receiver that makes computation efficient in terms of computational overhead as well as latency. Proposed model not only allows secure communication but also provides low computational and minimum latency.
