There is an exponential growth in the field of Internet of Things (IoT) assisted WSN with respect to the user credentials. Providing security is the first step process for efficient client-service association. Dynamic lightweight authenticity mechanism is proposed that utilizes the polynomial bivariate based key authentication for providing security. In this proposed scheme each node is assigned with polynomial bivariate keys. The link is generated after the verification of shared keys. By evaluating the polynomial shared keys the relay nodes are selected for the transmission. If both the sending and receiving nodes have the matching shared keys then the source node broadcast its random key. Authentication is carried out between the nodes through this polynomial key sharing system and hence the communication key is used for authentication.
