Andre Esser: Evaluating the security of code-based systems

The fourth round of the NIST standardization process requires agreement on secure parameters to be standardized. The central question is, how to choose these parameters to achieve necessary security guarantees under the best possible performance? There is an established methodology for parameter selection for pre-quantum primitives, which combines theoretical and practical results. In this talk, we outline this selection process using RSA as an example and determine how well code-based research has been able to adapt to it over the years. Eventually, we answer how far we are from a confident section of parameters for code-based NIST candidates and what remains to be done.

Break (15:15 - 15:45)
