Message authentication is the process that authenticates communications between two parties. Data confidentiality is the significant parameter used for measuring the ability of the system to protect the data. In the previous works, the system has two types of routing protocols, namely, single path routing and multi path routing. The function of a single path routing protocols is to make wise decision for the cost minimizing path, along the packets are send from source node to destination node, but it has failed to enable the security in it. In this article, we review methods adopted for wireless sensor network (WSN) and outline different method proposed in the literature. We compare the method based on the accuracy and we conclude this review with possible future directions.
