Message and node authentication is one among the foremost effective ways to prevent nodes from being propagated, forwarded, and corrupted, unauthorized messages over wireless sensor networks (WSNs). In order to alleviate those challenges, several message authentication schemes based on symmetric or public key cryptosystems have been developed. Despite various benefits, many challenges still exist in the attack mitigating in the wireless sensor network such as considering the reputation of a source and updating it dynamically by considering node transmission characteristics on packet data with the source and intermediate node acts neighbour. In addition, most of them have the constants of communication overhead, high computations, resilience and scalability. To address these issues, a novel polynomial-based scheme has been developed and it has been named Spatial Temporal based Distributed Message and Source Security Authentication Protocol. However, this scheme address all the weakness of built-in threshold-based schemes employed for message authentication in determining the degree of the polynomial. The puzzle-based node authentication has been enabled for intermediate nodes; the proposed scheme allows unlimited message transmission by any node without the struggling problem of the threshold.
