WarpAttack: Bypassing CFI through Compiler-Introduced Double-Fetches
Mathias Josef Payer, Flavio Toffalini, Luca Di Bartolomeo, Jianhao Xu
Code-reuse attacks are dangerous threats that attracted the attention of the security community for years. These attacks aim at corrupting important control-flow transfers for taking control of a process without injecting code. Nowadays, the combinations o ...
IEEE COMPUTER SOC2023Privacy-Enhancing Optical Embeddings for Lensless Classification
Martin Vetterli, Eric Bezzam, Matthieu Martin Jean-André Simeoni
Lensless imaging can provide visual privacy due to the highly multiplexed characteristic of its measurements. However, this alone is a weak form of security, as various adversarial attacks can be designed to invert the one-to-many scene mapping of such cam ...
2022Efficient Bootstrapping for Approximate Homomorphic Encryption with Non-sparse Keys
Jean-Pierre Hubaux, Juan Ramón Troncoso-Pastoriza, Jean-Philippe Léonard Bossuat, Christian Vincent Mouchet
We present a bootstrapping procedure for the full-RNS variant of the approximate homomorphic-encryption scheme of Cheon et al., CKKS (Asiacrypt 17, SAC 18). Compared to the previously proposed procedures (Eurocrypt 18 & 19, CT-RSA 20), our bootstrapping pr ...
SPRINGER INTERNATIONAL PUBLISHING AG2021Towards Efficient LPN-Based Symmetric Encryption
Serge Vaudenay, Sonia Mihaela Bogos, Dario Korolija, Thomas Locher
Due to the rapidly growing number of devices that need to communicate securely, there is still significant interest in the development of efficient encryption schemes. It is important to maintain a portfolio of different constructions in order to enable a ...
Springer International Publishing2021Cryptanalysis of LowMC instances using single plaintext/ciphertext pair
Serge Vaudenay, Subhadeep Banik, Fatma Betül Durak, Khashayar Barooti
Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned with ...
RUHR-UNIV BOCHUM, HORST GORTZ INST IT-SICHERHEIT2020Misuse Attacks on Post-quantum Cryptosystems
Serge Vaudenay, Loïs Evan Huguenin-Dumittan, Abdullah Talayhan, Fatma Betül Durak, Ciprian Baetu
Many post-quantum cryptosystems which have been proposed in the National Institute of Standards and Technology (NISI) standardization process follow the same meta-algorithm, but in different algebras or different encoding methods. They usually propose two ...
