What happened
Collection of new information-theory and coding-theory preprints. Highlights of security relevance: (1) A criterion determining when q-ary Goppa and certain primitive BCH codes attain their designed minimum distance — directly relevant to parameter selection and security estimates for code-based (post-quantum) cryptosystems. (2) Constructions of twisted linearized Reed–Solomon codes that give explicit LCD/ACD MDS families — relevant to code design for secure storage and potential implications for algebraic-structure attacks. (3) A Fourier-curve constellation demapping work that quantifies a ≈5
