Even-Mansour Space-hard Cipher: White-box Cryptography Cipher Meets Physically Unclonable Function
Takaki Asanuma, Takanori Isobe · Journal of Information Processing · 2023
Device authentication is essential between network-connected Internet of Things (IoT) devices and the systems connected to them to prevent security threats, such as leakage and tampering of information. However, there are cases where IoT devices with limited manufacturing costs do not have secure key storages. As cryptographic communication and authentication using symmetric keys may suffer from various attack opportunities, such devices should be secured against the white-box adversary, which can fully access the executing environment and the memory.
