    • 0-RTT Key Exchange with Full Forward Secrecy 

      Günther, Felix; Hale, Britta; Jager, Tibor; Lauer, Sebastian (Chapter, 2017)
      Reducing latency overhead while maintaining critical security guarantees like forward secrecy has become a major design goal for key exchange (KE) protocols, both in academia and industry. Of particular interest in this ...

    • Highly Efficient Key Exchange Protocols with Optimal Tightness 

      Cohn-Gordon, Katriel; Cremers, Cas; Gjøsteen, Kristian; Jacobsen, Håkon; Jager, Tibor (Journal article; Peer reviewed, 2019)
      In this paper we give nearly tight reductions for modern implicitly authenticated Diffie-Hellman protocols in the style of the Signal and Noise protocols, which are extremely simple and efficient. Unlike previous approaches, ...

    • Practical and tightly-secure digital signatures and authenticated key exchange 

      Gjøsteen, Kristian; Jager, Tibor (Journal article; Peer reviewed, 2018)
      Tight security is increasingly gaining importance in real-world cryptography, as it allows to choose cryptographic parameters in a way that is supported by a security proof, without the need to sacrifice efficiency by ...
