The software-defined networking (SDN) paradigm is widely regarded as the one that will govern networking in the future generation. The software-defined architecture for underwater acoustic sensor networks, also known as SDUASNs, has recently emerged as an important subject of discussion. The research that is being done on SDUASNs at the moment is, however, still in its early stages and is mostly concentrating on network design, data transfer, and routing. The scope of the SDUASNs is tough to grow, and the security maintenance is seldom dabbled in. These are two of the many limitations that exist. As a result, this research presents a scalable software-definition architecture for underwater acoustic sensor networks, also known as SSDUASNs. It does this by realising an organic integration of the three levels of knowledge, control, and data. The new nodes are able to readily access the network, which may be beneficial to the implementation of a widespread system. Then, the fundamental security authentication mechanism, also known as BSAM, is created using our architecture as the basis. In order to take use of the benefits of being flexible and programmable in SSDUASNs, the security authentication mechanism with pre-push, abbreviated as SAM-PP, is being presented in the further. In today's UASNs, the nodes authentication protocol is inefficient due to its high consumption and lengthy latency times. In addition, it is challenging to adjust to the constantly shifting surroundings. The two approaches have the potential to successfully resolve these issues. In comparison to other systems that are currently in use, BSAM and SAM-PP are better able to differentiate between legal nodes and malicious nodes, significantly reduce the amount of storage space used by nodes, and enhance the effectiveness of the operation of the network. In addition to this, SAM-PP has an additional benefit in that it shortens the time it takes to authenticate.
