Biography

Jakub Klemsa graduated in Mathematical Informatics programme at CTU in Prague with main interest in cryptography. In his diploma thesis, he proposed a novel extension to an attack against white-box implementations of ciphers. Thanks to these advances, he won an internship at Riscure, which is a world- class security lab. Currently, he is a third-year PhD student at CTU in Prague and his main focus is on theoretical guarantees as well as practical aspects of homomorphic cryptography.
