Zulke systemen die voortkomen uit cryptografische schema’s, en in het algemeen van praktische toepassingen zijn bijna altijd gestructureerd, maar de huidige algoritmen houden doorgaans geen rekening met deze structuur. In dit project zullen we een algoritmisch raamwerk ontwikkelen dat rekening houdt met de specifieke structuur die voortkomt uit het cryptosysteem en uit de interactie van de fysieke implementatie van het cryptosysteem met vijandige omgeving. Het raamwerk zal worden toegepast op post-kwantumschema’s om het vertrouwen in de veiligheidsanalyse van deze schema’s te vergroten.", "summary_en": "An algebraic attack is a cryptanalytic technique in which cryptographic schemes are modeled as systems of non-linear equations. Systems arising from cryptographic schemes, and in general from practical applications are almost always structured, but current algorithms typically do not take into account this structure. In this project, we will develop an algorithmic framework that takes into account the specific structure arising from the cryptosystem itself and from the interaction of the physical implementation of the cryptosystem with adversarial environment. The framework will be applied on post-quantum schemes in order to increase the confidence in the security analysis of these schemes.", "award_amount": 326737, "grant_id": "https://doi.org/10.61686/SQZXD91995", "project_members": [ { "role": "Main Applicant", "member_id": 503081, "last_name": "Samardjiska", "degree_pre_nominal": "dr.", "initials": "S.", "first_name": "Simona", "organisation": "Radboud Universiteit Nijmegen||Faculteit der Natuurwetenschappen, Wiskunde en Informatica||Institute for Computing and Information Sciences (ICIS)", "organisation_id": 79553, "ror": "https://ror.org/016xsfp80", "active": true }, { "role": "Project leader", "member_id": 503081, "last_name": "Samardjiska", "degree_pre_nominal": "dr.", "initials": "S.", "first_name": "Simona", "organisation": "Radboud Universiteit Nijmegen||Faculteit der Natuurwetenschappen, Wiskunde en Informatica||Institute for Computing and Information Sciences (ICIS)", "organisation_id": 79553, "ror": "https://ror.org/016xsfp80", "active": true }, { "role": "Researcher", "member_id": 528078, "last_name": "Ran", "initials": "l.a.", "first_name": "lARS", "organisation": "Radboud Universiteit Nijmegen||Faculteit der Natuurwetenschappen, Wiskunde en Informatica||Institute for Computing and Information Sciences (ICIS)||Digital Security (DiS) Group", "organisation_id": 76766, "ror": "https://ror.org/016xsfp80", "active": true } ], "products": [ { "title": "Algebraic Algorithm for the Alternating Trilinear Form Equivalence Problem", "year": 2023, "edition": "1", "start": 84, "end": 103, "type": "Productbijdrage", "url_open_access": "https://doi.org/10.1007/978-3-031-46495-9_5", "journal_title": "Springer, Cham.", "authors": [ { "last_name": "Esser", "initials": "A", "first_name": "Andre", "role": "Editor" }, { "last_name": "Ran", "initials": "L", "first_name": "Lars", "role": "Auteur" }, { "last_name": "Trimoska", "initials": "M", "first_name": "Monika", "role": "Auteur" }, { "last_name": "Santini", "initials": "P", "first_name": "Paolo", "role": "Editor" }, { "last_name": "Samardjiska", "initials": "S", "first_name": "Simona", "role": "Auteur" } ] }, { "title": "Reducing Signature Size of Matrix-Code-Based Signature Schemes", "year": 2024, "edition": "1", "start": 107, "end": 134, "type": "Productbijdrage", "url_open_access": "https://doi.org/10.1007/978-3-031-62743-9_4", "journal_title": "Springer, Cham.", "authors": [ { "last_name": "Smith-Tone", "initials": "D", "first_name": "Daniel", "role": "Editor" }, { "last_name": "Ran", "initials": "L", "first_name": "Lars", "role": "Auteur" }, { "last_name": "Saarinen", "initials": "M", "first_name": "Markku-Juhani", "role": "Editor" }, { "last_name": "Niederhagen", "initials": "R", "first_name": "Ruben", "role": "Auteur" }, { "last_name": "Samardjiska", "initials": "S", "first_name": "Simona", "role": "Auteur" }, { "last_name": "Chou", "initials": "T", "first_name": "Tung", "role": "Auteur" } ] }, { "title": "Rare Structures in Tensor Graphs - Bermuda Triangles for Cryptosystems Based on the Tensor Isomorphism Problem", "year": 2024, "edition": "1", "start": 66, "end": 96, "type": "Productbijdrage", "url_open_access": "https://doi.org/10.1007/978-981-96-0944-4_3", "journal_title": "Springer", "city": "Singapore", "authors": [ { "last_name": "Ran", "initials": "L", "first_name": "Lars", "role": "Auteur" }, { "last_name": "Samardjiska", "initials": "S", "first_name": "Simona", "role": "Auteur" }, { "last_name": "Chung", "initials": "KM", "role": "Editor" }, { "last_name": "Sasaki", "initials": "Y", "role": "Editor" } ] }, { "title": "MEDS - Matrix Equivalence Digital Signature Scheme", "year": 2023, "type": "Overige Output", "url_open_access": "https://www.meds-pqc.org/", "authors": [ { "last_name": "Samardjiska", "initials": "S", "first_name": "Simona", "role": "Maker" }, { "last_name": "Persichetti", "initials": "E", "role": "Maker" }, { "last_name": "Reijnders", "initials": "K", "role": "Maker" }, { "last_name": "Ran", "initials": "L", "role": "Maker" }, { "last_name": "Trimoska", "initials": "M", "role": "Maker" }, { "last_name": "Niederhagen", "initials": "R", "role": "Maker" }, { "last_name": "Chou", "initials": "T", "role": "Maker" }, { "last_name": "Hajatiana Randrianarisoa", "initials": "T", "role": "Maker" } ] } ] } ] }
