    摘要: Some embodiments are directed to a cryptographic method for providing an electronic first device, an electronic second device and an electronic intermediary device, the cryptographic method establishing a cryptographically protected communication channel between the first device and the second device. The method comprises establishing a session identifier (SID) between the first device and the intermediary device. The first device sends the session identifier and a first key element to the second device over an out-of-band channel. The second device sends a registration message comprising the session identifier to the intermediary device. The first and second device can communicate through the intermediary device protected using a shared key derived at the first and second device.

    摘要: A cryptographic system for reproducibly establishing a reliable data string, such as a cryptographic key, from a noisy physically unclonable function (PUF, 110) is provided. The system comprises a hard decision decoder (150) to decode a first multiple of error correctable data words to obtain a second multiple of corrected and decoded data words and a reliability information extractor (180) to determine reliability information, e.g. soft decision information, that is indicative of a reliability of corrected and decoded data words. The system further comprises a soft decision decoder (160) configured to use the reliability information to decode at least one further correctable data word. Error correcting a PUF using reliability information decreases the false rejection rate.
