Cryptography Seminar

Title: Quantum Key Distribution - Transitioning to Future Cryptography Speaker: Andrei Andries (masterand SAL, UB) Abstract: The talk discusses Quantum Key Distribution (QKD), which marks the transition from mathematics-based to physics-based cryptography. While QKD is in continuous development, there are still unsolved issues (such as long-distance transmission and hardware limitations).

Title: Making zkSNARKs Non-Malleable Speaker: Antonio Faonio (Eurecom) Abstract: Zero-knowledge SNARKs (zkSNARKs) are cryptographic proof systems that allow a prover to convince a verifier that a statement is true, with very small proofs and fast verification, without revealing the underlying witness. The standard security notion for SNARKs is knowledge soundness, which guarantees that any prover

Title: Hidden subgroup problem Speaker: Mihai Prunescu (UB) Abstract:A subgroup H of G = F2 x .... x F2 is implicitly given by a function rho on G. The function rho is constant on classes H+x. A classical quantum algorithm is able to find a generating set of H.   Acknowledgement: This seminar talk is (in
