ZISC makes key contributions to private contact tracing DP-3T

The current Covid-19 pandemic has triggered an unforeseen interest in smartphone-based contract tracing technologies. If carefully designed and widely deployed, such systems may significantly help the medical authorities to track infection chains, prevent new outbreaks and thus save many lives. At the same time, any smartphone-based tracing solution has inherent privacy concerns. If the system

TLS-N from ZISC researchers makes websites “blockchain-ready”

ZISC researchers Hubert Ritzdorf, Karl Wust, Arthur Gervais, Guillaume Felley, Srdjan Capkun have released TLS-N, an extension of TLS that enables the seamless integration of non-repudiation between arbitrary parties within TLS. TLS-N allows the generation of privacy-preserving, non-repudiable, non-interactive proofs for the contents of a TLS session. TLS-N provides a trusted data relay. Therefore, it
