SUMMARY:Collusion Resistant Copy-Protection for Watermarkable Functionaliti
 es
CLASS:PUBLIC
DESCRIPTION:CS/MATH SEMINAR - JIAHUI LIU (UT AUSTIN)\n\nCopy-protection is 
 the task of encoding a program into a quantum state\nto prevent illegal du
 plications. A line of recent works studied\ncopy-protection schemes under 
 ``1 -> 2 attacks'': the adversary\nreceiving one program copy can not prod
 uce two valid copies. However\,\nunder most circumstances\, vendors need t
 o sell more than one copy of a\nprogram and still ensure that no duplicate
 s can be generated. In this\nwork\, we initiate the study of collusion res
 istant copy-protection in\nthe plain model. Our results are twofold:
