SUMMARY:Elena Egorova (Skoltech\, Moscou): Codes with identifiable parent &
  traceability properties\, and broadcast encryption
DESCRIPTION:Elena Egorova: In this talk we address the problem of broadcast
  encryption schemes resistant to collusion attacks of malicious users and 
 consider the corresponding mathematical models known under the name of IPP
  codes and Traceability codes. For any set U of q-ary vectors of length n 
 we define its convex hull &lt\;U&gt\; as the set of vectors z such that ea
 ch coordinate of z coincides with corresponding coordinate of at least one
  vectors of U. A q-ary code C of length n is called a t-IPP code if for an
 y q-ary vector z either intersection of all t-subsets U of C such that z 
 ∈ &lt\;U&gt\; is non-empty or there is no t-subsets U of C such that z 
 ∈ &lt\;U&gt\; . We describe the known results as well as some open probl
 ems concerning IPP codes and traceability codes.\n\nhttps://www.researchga
