SUMMARY:Fully Homomorphic Encryption (FHE)
DESCRIPTION:Speaker:  Ana Costache \n\nAbstract: \n\n\n\n\n\n\nFully 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.

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.
