A new era of Internet of Things (IoT) will emerge in near future due to the rapid innovations and advancements in computing and communication technologies. In order to make IoT era become possible, sensitive data in IoT devices such as cryptographic keys should be protected from malicious attackers. In particular, cryptographic keys are vital for securing systems and communication. In this paper, we study a sensitive data hiding scheme for IoT devices using software obfuscation techniques. Proposed scheme exploits function call obfuscation and creates a hidden area between functions to secretly store sensitive data. The proposed scheme outperforms the legacy hardware-based schemes which impose additional hardware cost to IoT devices.
