Design and Cryptanalysis of Lightweight Symmetric Key Primitives
In this paper, we present a new Private Set Intersection (PSI) protocol that is extremely efficient and highly scalable compared with existing protocols. The ...
Automated Methods in Cryptanalysis and Design of Symmetric-Key ...In this model, the protocol security problem is transformed into a search based on a term rewriting system [6]. Given a security protocol and a security ... When Private Set Intersection Meets Big Data: An Efficient and ...We give transformations that substantially reduce the size of boolean circuits if the costs for evaluating XOR gates are lower than for other types of gates. Vers l'efficacité et la sécurité du chiffrement homomorphe et du ...Another possibility is to XOR all eight lookup results. This is very useful for ciphers that. XOR the results of multiple table lookups, such as AES (Figure ... INTERNSHIP REPORT Supporting additional equational theories in ...... Multi-collisions. Une r-multi-collision est un ensemble de r messages qui ont tous le même haché. Pour construire une r-multi-collision dans une fonction ... Engineering Secure Two-Party Computation Protocols? In symmetric-key cryptography, both parties need to know the key before the communication in order to establish the secure channel. ? However, the problem is ... Construction et Analyse de Fonctions de Hachage - 400 Bad RequestOur construction follows a simple design approach, applying the hash function to the XOR of multiple hash values. The construction calls to mind ... Evolutionary Computation and Cryptology - CMAPStill, a proof in the ideal cipher model seems useful because it shows that a scheme is secure against generic attacks, that do not exploit specific weaknesses ... Correcting Subverted Random Oracles - Cryptology ePrint ArchiveWe apply this model to the standardized block cipher PRESENT. Finally, we present very generic attacks on two authenticated encryption schemes, ...
