Towards 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-SICHERHEIT2020Analysis of the BIKE post-quantum cryptographic protocols and the Legendre pseudorandom function
The field of post-quantum cryptography studies cryptographic systems that are secure against an adversary in possession of a quantum computer. In 2017, the National Institute of Standards and Technology (NIST) initiated a process to standardize quantum-res ...
EPFL2020Misuse 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 ...
SPRINGER INTERNATIONAL PUBLISHING AG2019On Secure Cloud Computing for Genomic Data: From Storage to Analysis
Although privacy is generally considered to be the right of an individual or group to control information about themselves, such a right has become challenging to protect in the digital era, this is exemplified by the case of cloud-based genomic computing. ...
EPFL2018Breaking The FF3 Format-Preserving Encryption Standard Over Small Domains
Serge Vaudenay, Fatma Betül Durak
The National Institute of Standards and Technology (NIST) recently published a Format-Preserving Encryption standard accepting two Feistel structure based schemes called FF1 and FF3. Particularly, FF3 is a tweakable block cipher based on an 8-round Feistel ...
2017Some Cryptanalytic Results on Lizard
Lizard is a lightweight stream cipher proposed by Hamann, Krause and Meier in IACR ToSC 2017. It has a Grain-like structure with two state registers of size 90 and 31 bits. The cipher uses a 120 bit secret key and a 64 bit IV. The authors claim that Lizard ...
