For low-resource internet-of-things (IoTs) like wearables, health-monitors, tags and sensors, existing authentication techniques (e.g., encryption, strong hash functions, pseudorandom number generators) might be impractical for securing access to critical data. This is because these devices have limited computational bandwidth; limited energy; and require real-time authentication. Static identifiers like bar-codes, product IDs, embedded physical unclonable functions (PUFs) or stored private keys are vulnerable to theft, counterfeiting, replay attacks or tampering. In this gap, Secure Dynamics is delivering enterprise-grade security solutions for energy-constrained Internet-of-things using zero-power timers. This solution uses zero-power timers to generate dynamic tokens that are secure against any power side-channel attacks, eaves-dropping and tampering. The hardware-software solution also supports mutual authentication, where the IoT device could also query and verify the trust of its reader.
