Prof. Capkun new member of the IC3 blockchain initiative

IC3, an initiative of faculty members at Cornell University, Cornell Tech, UC Berkeley, UIUC, and the Technion, offers world-class expertise in computer science that spans cryptography, distributed systems, game theory, programming languages, and system security techniques. IC3’s innovations include new blockchains, smart contracts, and cryptocurrency technologies that offer both the scientifically rigorous security properties and

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

ZISC researchers present new way to analyze Bitcoin security

Blockchain systems like Bitcoin are gaining increasing attention, but at the same time their security guarantees remain not well understood, due to the difficulty of precisely modeling their functionality and proving their security. In a recently published research paper, ZISC researcher Christian Badertscher and his colleagues present a new approach for creating proofs of security
