Transport protocols for Wireless Sensor Networks (WSNs) are designed to fulfill both reliability and energy efficiency requirements. Distributed Transport for Sensor Networks (DTSN) [1] is one of the most promising transport protocols designed for WSNs because of its effectiveness; however, it does not address any security issues, hence it is vulnerable to many attacks. The first secure transport protocol for WSN was the secure distributed transport protocol (SDTP) [2], which is a security extension of DTSN. Unfortunately, it turns out that the security methods provided by SDTP are not sufficient; some tricky attacks get around the protection mechanism. In this paper, we describe the security gaps in the SDTP protocol, and we introduce SDTP+for patching the weaknesses. We show that SDTP+resists attacks on reliability and energy efficiency of the protocol, and also present an overhead analysis for showing its effectiveness.
