Postdoc Sven Puchinger with co-authors from TU Munich (Julian Renner and Antonia Wachter-Zeh), German Aerospace Center (Thomas Jerkovits and Hannes Bartz), and Université de Rennes 1 (Pierre Loidreau) got a paper accepted at the International Conference on Post-Quantum Cryptography (PQCrypto) 2020:
“Randomized Decoding of Gabidulin Codes Beyond the Unique Decoding Radius”, Julian Renner, Thomas Jerkovits, Hannes Bartz, Sven Puchinger, Pierre Loidreau, Antonia Wachter-Zeh [link] [arXiv]
The paper proposes a significantly faster algorithm to solve a decoding problem which the security of three code-based cryptosystems is based on.
