Project Details


RFID technology is treated as one of the main enabler for the future Internet of Things. RFID systems consist of tags, readers and a backend system. The tags basically provide their ID to any reader that is querying the tags. Additional functionality like authentication or secure communication of tags or readers is not considered in the existing standards. We are confident that profound security measures for RFID systems will not only enable a variety of new RFID applications, but also contribute to solve the currently ongoing privacy discussion concerning current RFID technology. Within CRYPTA we will build a future RFID application prototype extended by state-of-the-art security functionality (proof-of-origin) and build a fully-functional cryptographic enabled tag prototype chip for this purpose. In order to embed additional modules (crypto) into passive RFID tags, we will design a new flexible tag architecture considering all sub-components. With this generic architecture it shall be easy to integrate new functionality into tags and to reduce the time-to-market for future RFID tags. One of the most ambitious goals of CRYPTA is the design of an asymmetric cryptographic module (ECDSA) suitable for passive RFID tags. This cryptographic module will be integrated in the developed tag architecture to build the tag prototype. The prototype should be the first passive RFID tag ever produced that supports a standardized asymmetric cryptographic signature algorithm (ECDSA). The prototype tags will be used in the application prototype to show the applicability of our developments.
