Offene Themen

• Title: Security Analysis of MAYO (Master thesis)
  Description: MAYO is a recently published signature scheme based on multivariate quadratic equations. Its performance and key sizes are compatible to lattice-based signature schemes, including NIST's finalists Dilithium and Falcon. An appealing task for such a young scheme is to investigate it regarding possible improvements in cryptanalysis. Like Rainbow and LUOV, MAYO is a modification of UOV. The past has shown that such modifications can lead to additional attack vectors, that might be exploited. Thus, a detailed security analysis is an important step in the development process of MAYO.

• Title: Analyzing attacks against code-based signatures (Master thesis)
  Description: Three signature schemes based on codes were submitted to the NIST PQC standardization process. During the first round, all of these submissions have been broken. The goal of this thesis is identify design mistakes made in the development of these signature schemes by analyzing the attacks and looking for similarities and differences.
