Abstract Cloud services and the internet of things, which operate in dynamic multi-user and multi-device environments, require scalable, real-time authentication. However, conventional static key management systems lack flexibility and security. Here we report on a security system based on physical unclonable functions that uses chaotic vertical-cavity surface-emitting lasers as entropy sources for key generation.
