SUMMARY:Quantum Key Distribution - Transitioning to Future Cryptography
DESCRIPTION:Title: Quantum Key Distribution – Transitioning to Future Cryptography \nSpeaker: Andrei Andries (masterand SAL\, UB) \n\nAbstract: The talk discusses Quantum Key Distribution (QKD)\, which marks the transition from mathematics-based to physics-based cryptography. While QKD is in continuous development\, there are still unsolved issues (such as long-distance transmission and hardware limitations).

SUMMARY:Making zkSNARKs Non-Malleable
DESCRIPTION:Title: Making zkSNARKs Non-Malleable \nSpeaker: Antonio Faonio (Eurecom) \n\nAbstract: Zero-knowledge SNARKs (zkSNARKs) are cryptographic proof systems that allow a prover to convince a verifier that a statement is true\, with very small proofs and fast verification\, without revealing the underlying witness. The standard security notion for SNARKs is knowledge soundness\, which guarantees that any prover who convinces the verifier must “know” a valid witness. A stronger notion is simulation extractability\, which ensures that even an adversary who has seen simulated proofs cannot create a new valid proof without actually knowing a witness\, and in particular implies non-malleability. This stronger guarantee is especially important in distributed and adversarial settings\, where proof malleability can become a real threat. In this talk\, we revisit simulation extractability for universal zkSNARKs in the PIOP-to-SNARK paradigm. We discuss how this property can be achieved and analyzed in systems used in practice\, with particular attention to optimizations such as the linearization trick. We also place these results in a broader context\, reviewing existing approaches to simulation extractability in the literature and highlighting alternative techniques and trade-offs. The goal is to give a unified and accessible picture of how simulation extractability can be obtained in modern zkSNARK constructions\, and what design choices are needed to ensure it in practice. \n  \n\nAcknowledgement: This seminar talk is due to the PATTERN CHIST-ERA project https://chistera-pattern.github.io/ ; https://sites.google.com/unibuc.ro/patternub \n \nPATTERN receives funding from the French National Research Agency under Grant Agreement No. ANR-23-CHR4-0008\, the Luxembourg National Fund under Grant Agreement No. INTER/CHIST23/17931746\, and the Romanian Ministry of Research\, Innovation and Digitization\, CNCS/CCCDI – UEFISCDI\, project number ERANET-CHISTERA-IV-PATTERN\, within PNCDI IV.

SUMMARY:BLOCKCHAIN - More than a buzzword
DESCRIPTION:Title: BLOCKCHAIN – More than a buzzword \nSpeaker: Ionut-Daniel Dobos (MBN Technologies) \n\nAbstract: In this presentation we will take a look at the concept of a blockchain as a mean to hold historical transactional data (while maintaining all the core concepts of Cryptography) and moreover\, to see how IPFS uses such approaches to ensure a way of general data storage with the same capabilities. We will choose the Ethereum network as a use case for the first topic\, taking a deeper look into the upcoming Casper update for the consensus mechanism\, introducing the Proof of Stake paradigm.

SUMMARY:Functional Encryption (FE)
DESCRIPTION:Speaker:  Radu Titiu \n\nAbstract: \nFunctional 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 produca alta cheie secreta K_f asociata unei functionalitati f. Folosind cheia K_f un utilizator poate sa obtina f(mesaj) si nimic mai mult. O astfel de primitiva criptografica ar putea fi utilizata de un spital care tine datele pacientilor criptate dar care poate totusi oferi acces cercetatorilor la anumite statistici care ar putea ajuta la intelegerea anumitor boli. Toate acestea sunt posibile fara a divulga informatii despre pacienti.\nIn aceasta prezentare Radu va explica detaliat ce inseamna Functional Encryption si posibile aplicatii. De asemenea\, va exemplifica conceptul printr-o constructie pentru o clasa restransa de functionalitati [2] si va vorbi despre cerintele de securitate pe care le satisface aceasta constructie.\nReferinte:\n[1] https://link.springer.com/chapter/10.1007%2F978-3-319-70500-2_8\n[2] https://eprint.iacr.org/2015/608.pdf

SUMMARY:Criptosistemul lui McEliece\, dupa 40 de ani de criptanaliza
DESCRIPTION:Speaker:  Vlad Dragoi (Univ. Aurel Vlaicu Arad) \n\nAbstract: \nAceasta prezentare are ca scop descrierea principalelor solutii de criptare asimetrica cu ajutorul codurilor corectoare de erori. Vom incerca sa discutam cat mai multe aspecte legate de aceste protocoale\, cum ar fi: natura codurilor folosite in acest context\, complexitatea algoritmilor de criptare si decriptare\, securitatea protocolului (distinguisher\, message recovery attacks\, key recovery attacks). Daca timpul ne permite vom incerca sa detaliem una dintre variante\, de exemplu McEliece textbook cu codurile Goppa binare.
