Efficient and Quantum-safe Internet Key Exchange Protocols for Satellite Communications
Davide De Zuane, Marco Baldi, Paolo Santini +4
This paper studies cryptographic key exchange in satellite communications, which requires specific solutions because the satellite context presents unique challenges, particularly…
The Power of Power Codes: New Classes of Easy Instances for the Linear Equivalence Problem
Michele Battagliola, Anna-Lena Horlemann, Abhinaba Mazumder +4
Given two linear codes, the Linear Equivalence Problem (LEP) asks to find (if it exists) a linear isometry between them; as a special case, we have the Permutation Equivalence Prob…
Near-Codewords Aware Bit Flipping Decoding of QC-MDPC Codes
Alessio Baldelli, Marco Baldi, Davide De Zuane +1
Bit-Flipping (BF) decoders are a family of decoders widely employed in post-quantum cryptographic schemes based on Quasi-Cyclic Moderate-Density Parity-Check (QC-MDPC) codes, such…
Implementation and transition to post-quantum cryptography of the Minimal IKE protocol
Davide De Zuane, Paolo Santini, Marco Baldi
This paper concerns the Minimal Internet Key Exchange (IKE) protocol, which has received little attention to date, despite its potential to make the best-known IKE protocol suffici…
BF-Max: an Efficient Bit Flipping Decoder with Predictable Decoding Failure Rate
Alessio Baldelli, Marco Baldi, Franco Chiaraluce +1
The Bit-Flipping (BF) decoder, thanks to its very low computational complexity, is widely employed in post-quantum cryptographic schemes based on Moderate Density Parity Check code…
