Speaker: Radu Titiu Abstract: Functional Encryption (FE) este o primitiva criptografica moderna care generalizeaza notiunea de criptografie cu cheie publica in felul urmator. In mod normal algoritmul de decriptare se foloseste de cheia secreta pentru a recupera intreg mesajul criptat cu cheia publica. FE permite o decriptare controlata a mesajului: detinatorul cheii secrete K poate sa …
Speaker: Alin Puncioiu (Secureworks) Abstract: In cadrul prezentarii vom prezenta cateva fluxuri de lucru executate manual in momentul de fata pe parcursul fazelor de raspuns la incidente cibernetice.
Speaker: Mihai Prunescu (University of Bucharest) Abstract: Regular logic systems which are strictly stronger than the first order predicate calculus cannot satisfy in the same time Löwenheim-Skolem for statements and compacity (Lindström 1). Effectively presented such systems cannot satisfy in the same time Löwenheim-Skolem for statements and the condition that the set of generally valid …
Speaker: Ana Costache Abstract: Fully homomorphic encryption este un tip de criptare care permite manipularea datelor criptate pastrand securitatea acestora. Ana va introduce notiunea de latice, si va defini FHE. De asemenea, va vorbi despre librarii FHE si despre relevanta FHE in lumea comerciala.
Speaker: Alexandru Dragomir (University of Bucharest) Abstract: Epistemic logics - logics aimed at reasoning about knowledge and belief - are widely considered to be suitable for modelling, analyzing and predicting vulnerabilities of security protocols. One of the first and most discussed logical approaches to the problem of verifying security protocols is the one proposed in …

Speaker: Bogdan Ghimiș (University of Bucharest) Abstract: From a security perspective, discovering bugs before shipping a product is crucial. This presentation will be about RIVER, a tool that can help us to inspect x86 binary code. This lecture will encompass two papers describing methods of finding problematic inputs: a genetic algorithm and a method using …
Speaker: Mihai Prunescu (University of Bucharest) Abstract: We discuss different implications of the negative answer of Hilbert's Tenth Problem: the exponential Diophantine equation over ℕ and ℚ, the minimal number of variables which lead to an undecidable problem over ℤ, the homogeneous Diophantine problem over ℤ.
Speaker: Ruxandra Olimid (University of Bucharest) Abstract: Short (crypto) introduction in Blockchain. Mostly a reading group, discussing the original bitcoin paper: https://bitcoin.org/bitcoin.pdf
