WebNotions of Black-Box Reductions, Revisited Paul Baecher1 Christina Brzuska2 Marc Fischlin1 1 Darmstadt University of Technology, Germany 2 Tel-Aviv University, Israel November 29, 2013 Abstract. Reductions are the common technique to prove security of cryptographic construc- tions based on a primitive. WebWe revisit memory-tightness on black-box reductions, and show several lower bound results. Lower bound for unique signatures. In [6], Coron proved a tightness lower bound of black-box reductions from the security of unique signatures [10,20,19], in which there exists only one valid signature for each pair of public key (not how to send videos to google chromecast https://oppgrp.net

It is also known that the most desired form of commitments in terms of their round complexity, i.e., non-interactive commitments, cannot be built from one-way functions in a black-box way [Mahmoody-Pass, Crypto’12].

We say that R is a C-black-box reduction from P to P0, if R is a probabilistic polynomial-time oracle machine such that for every oracle A 2 C that solves P0, RA solves P.
