PHYSEC-ProPair (“Proximity Pairing”) is a highly secure pairing solution consisting of a software and hardware part. It enables the ad-hoc authentication of wirelessly communicating devices towards each other. This solution offers an elegant alternative to any pre-shared key solution by authenticating devices based on their proximity.
The PHYSEC-ProPair hardware module can be attached to any smartphone and turns it into an authentication device. The headphone jack is used as connector, therefore the hardware can be used with any type of Smartphone (e.g. Samsung Nexus 5 or IPhone 6).
The software is designed particularly for being used in embedded systems which typically have only a low amount of memory and energy available, such as 8051, AVR, MSP430, ARM M0+, and ARM M3 microcontrollers or SoCs like the cc111x and cc253x platforms.
