This document presents a novel routing protocol called SSAAR that aims to provide end-to-end throughput and secure data transmission in multi-hop wireless networks. The protocol uses an hop-by-hop authentication scheme using elliptic curve cryptography where each user generates a public/private key pair. When a source node wants to transmit data, it generates a digital signature for the message using its private key. Intermediate nodes can verify the signature using the source's public key to authenticate the message. The protocol is evaluated experimentally and results show it can effectively provide security and reliability for wireless data transmission.
