Intrusion Detection Systems over an Encrypted Traffic: Problem and Solutions
Orateur : Sébastien Canard (Orange)
Privacy and data confidentiality are today at the heart of many discussions. But such data protection should not be done at the detriment of other security aspects. In the context of network traffic, intrusion detection system becomes in particular totally blind when the traffic is encrypted, making clients again vulnerable to known threats and attacks. Reconciling security and privacy is then one[…] -

Private Set Intersection and Other Private Information Sharing Protocols
Orateur : Xavier Carpent (University of Nottingham)
In this seminar, we will give an overview of Private Set Intersection (PSI), some of its constructions, use cases, and open research questions. The canonical PSI protocol allows Alice and Bob (both with their own set of elements) to interact in a way that Alice learns the intersection of the sets and nothing else. Numerous variants exist:cardinality of intersection only (how many elements in[…] -

Squirrel: a new approach to computer-assisted proofs of protocols in the computational model.
Orateur : David Baelde (ENS Cachan)
Formal methods have brought several approaches for proving that security protocols ensure the expected security and privacy properties. Most of the resulting tools analyze protocols in symbolic models, aka. Dolev-Yao-style models. Security in the symbolic model does not imply security in the cryptographer’s standard model, the computational model, where attackers are arbitrary (PPTIME) Turing[…] -

True Random Number Generators enabled hardware security
Orateur : Bohan Yang
True randomness is all about unpredictability, which can neither be qualified nor quantified by examining statistics of a sequence of digits. Unpredictability is a property of random phenomena, which is measured in bits of information entropy. Application of randomness spans from art to numerical computing and system security. Random numbers enable various cryptographic algorithms, protocols and[…] -

Post-Quantum Cryptography Hardware: Monolithic Implementations vs. Hardware-Software Co-Design
Orateur : Markku-Juhani Saarinen
At PQShield, we’ve developed dedicated coprocessor(s) for lattice schemes, hash-based signatures, and code-based cryptography. These cryptographic modules are commercial rather than academic and designed to meet customer specifications such as a specific performance profile or Common Criteria and FIPS security certification requirements.Hardware implementations of legacy RSA and Elliptic Curve[…] -

Security challenges and opportunities in emerging device technologies: a case study on flexible electronics
Orateur : Nele Mentens - KU Leuven, Belgium
While traditional chips in bulk silicon technology are widely used for reliable and highly ef?cient systems, there are applications that call for devices in other technologies. On the one hand, novel device technologies need to be re-evaluated with respect to potential threats and attacks, and how these can be faced with existing and novel security solutions and methods. On the other hand,[…] -
