Flash memory and true random number generators (TRNGs) can be essential components of security systems for smart devices. Using physical variations in integrated circuit (IC) constituent components is an increasingly popular technique for generating true random numbers. An existing approach uses a technique called “partial programming” to...

Current portable and wearable devices use fingerprint analysis for secure authentication. The fingerprint pattern systems analyze only the surface morphology of the fingerprint, making it easy for hackers to spoof and bypass authentication. RF signals can collect tissue information beyond the surface of the finger and can provide increased security...
