Lower and Upper Bounds on the Randomness Complexity of Private Computations of AND
Thời gian : 14:30
Người thuyết trình : Damien Vergnaud
(joint work with Eyal Kushilevitz, Rafail Ostrovsky, Emmanuel Prouff, Adi Rosen & Adrian Thillard)
We consider multi-party information-theoretic private protocols, and specifically their randomness complexity. The randomness complexity of private protocols is of interest bot...

Optimizing Multiple Objectives for Clustering
Thời gian : 10:00
Người thuyết trình : Sanghamitra Bandyopadhyay (Indian Statistical Institute)
Clustering is an unsupervised exploratory data analysis tool which groups the data on the basis of some similarity/dissimilarity metric such that a predefined criterion is optimized. The problem of clustering is therefore essentially one of optimization. The use of metaheuristics...

- Brute-Force Cryptanalysis with Aging Hardware: Controling Half the Output of SHA-256
Thời gian : 14:30
Người thuyết trình : Charles Bouillaguet
This paper describes three random-looking bit strings whose hashes by SHA-256
maintain a non-trivial relation: their XOR starts with 128 zero bits. They have
been found by brute-force, without exploiting any cryptographic weakness in the
hash function itself. This shows that birt...

- Wave: a New Family of Trapdoor One-Way PSF Based on Codes
Thời gian : 14:30
Người thuyết trình : Thomas Debris
(joint work with Nicolas Sendrier and Jean-Pierre Tillich)
We present here a new family of trapdoor one-way Preimage Sampleable Functions (PSF) based on codes, the Wave-PSF family. The trapdoor function is one-way under two computational assumptions: the hardness of gene...
