1-2 PhD Students in Computing Science with focus on Cryptography and Cybersecurity Umeå University, Umeå, Sweden At our department, which conducts research at the highest international level and offers several high-quality educational programs in Computer Science, we are now seeking 1-2 PhD students with a focus on Cryptography and Cybersecurity. The project focuses on the design and analysis of modes of operation for symmetric-key cryptography, including, but not limited to, message authentication codes, pseudorandom functions, encryption schemes, deck functions, hash functions, and hash-based signatures, for applications such as quantum-secure and post-quantum cryptography, and leakage- and tamper-resilient cryptography. It is supervised by Asst. Prof. Mustafa Khairallah. The research is expected to include a mixture of theory and practice. The selected students will be part of the Department of Computing Science at Umeå University, as well as the WASP graduate school. The exact rese...
