Секция “Математически основи на информатиката” към ИМИ - БАН, Ви кани на поредната сбирка на семинара си, на която Grigory Kabatiansky, Skolkovo Institute of Science and Technology, ще изнесе доклад на тема: On combinatorics of tracing traitors codes.  Резюме. Tracing traitors codes were invented by Chor, Fiat and Naor 25 years ago. Later these codes were renamed as IPP-codes (codes with the identifiable parent property). It is an interesting combinatorial object related to separating codes, cover-free family of sets and error-correcting codes also. I'll discuss some known results as well as open problems. Семинарът ще се проведе на 17 септември 2019 г. от 14:00 часа в зала 503 на ИМИ-БАН.
