Tjerand Silde
About
I am an Associate Professor in Cryptology at the Department of Information Security and Communication Technology, where I am the Research Group Leader of the NTNU Applied Cryptology Lab. I am also affiliated with the Department of Mathematical Sciences at NTNU and working as a Security and Cryptography Expert at the cybersecurity company Pone Biometrics.
I defended my PhD thesis on August 22nd, 2022, titled: Privacy-Preserving Cryptography from Zero-Knowledge Proofs. I started as an Associate Professor on September 1st, 2022. You can find more information at: tjerandsilde.no.
Research
My main foci of research are lattice-based cryptography and zero-knowledge protocols. My interests also span the areas of post-quantum cryptography, anonymous communication, multiparty computation, homomorphic encryption, electronic voting, and secure implementation.
