Masking Based Domain Extenders for UOWHFs: Bounds and Constructions
We study the class of masking based domain extenders for UOWHFs. Our first contribution is to show that any correct masking based domain extender for UOWHF which invokes the compr...

A Public-Key Black-Box Traitor Tracing Scheme with Sublinear Ciphertext Size Against Self-Defensive Pirates
We propose a public-key traitor tracing scheme in which (1) the size of a ciphertext is sublinear in the number of receivers and (2) black-box tracing is efficiently achieved again...
