Due to the nature of the public channel, designing authentication techniques suitable for wireless sensor networks (WSNs) that satisfy the dedicated considerations is critical. In 2022, Liu et al. presented an authentication protocol that employs dynamic authentication credentials (DACs) and Intel software guard extensions (SGX) to guarantee security in WSNs. Then, they proved that it is secure by formal and informal security analysis. This paper shows that it is not secure against desynchronization and offline guessing attacks for long-term random numbers of users. In addition, it suffers from the known session-specific temporary information attack. Then, an improved authentication scheme using DAC and Intel SGX will be presented to address these vulnerabilities. We show that it is secure against the aforementioned attacks by employing formal and informal analysis and has a reasonable communication and computation overhead. It should be highlighted that our proposal’s communication and computation overheads are increased negligibly, but it provides more security features compared to the baseline protocol.
