Fault Attacks on Nonce-based Authenticated Encryption: Application to Keyak and Ketje [PDF]
, 2018 In the context of fault attacks on nonce-based authenticated encryption, an attacker faces two restrictions. The first is the uniqueness of the nonce for each new encryption that prevents the attacker from collecting pairs of correct and faulty outputs ...

Optimizing S-box Implementations for Several Criteria using SAT Solvers [PDF]
, 2017 We explore the feasibility of applying SAT solvers to optimizing implementations of small functions such as S-boxes for multiple optimization criteria, e.g., the number of nonlinear gates and the number of gates.

Mathématiques discrètes appliquées à la cryptographie symétrique [PDF]
, 2018 In this thesis, we study the security of symmetric cryptographic primitives. These systems are based on transformations relying on mathematical objects that can be represented in multiple ways.

Joseph Milot : cordonnier, cocher, trésorier. Un humble militant dans la grande histoire
, 2022 editorial reviewedIn dit artikel focussen we op de activist Joseph Milot (1854-1934). Als Brussels ‘ketje’, schoenmaker, koetsier, beheerder van de informatie- en propagandamiddelen van de Belgische Werkliedenpartij (BWP/POB) was Milot betrokken bij het ...

A New Authenticated Encryption Technique for Handling Long Ciphertexts in Memory Constrained Devices [PDF]
, 2015 In authenticated encryption schemes, there are two techniques for handling long ciphertexts while working within the constraints of a low buffer size: Releasing unverified plaintext (RUP) or Producing intermediate tags (PIT).

Institutions for Collective Action: Kroniek van een Bazenbondje, interview met Ad van Sundert
, 2016 ‘Het is eigenlijk een woongebied waar industrie tussen zat.’ Ad van Sundert geeft in deze zin kernachtig het leven, werken en wonen neer in het Nieuwendam zoals dat na de Tweede Wereldoorlog was. ‘Maar’, zo zegt hij erbij, ‘Later werd dat minder’.

New MILP Modeling: Improved Conditional Cube Attacks on Keccak-based Constructions [PDF]
, 2018 In this paper, we propose a new MILP modeling to find better or even optimal choices of conditional cubes, under the general framework of conditional cube attacks. These choices generally find new or improved attacks against the keyed constructions based

Evaluation of CAESAR candidates on FPGA
, 2016 Het beveiligen van data is essentieel in ons leven. Omdat krakers manieren vinden om bestaande cryptografische algoritmen te kraken, moeten deze evolueren. Authenticated encryption (AE) biedt zowel confidentiality als authenticity van data simultaan aan.
