Tighter Adaptive IBEs and VRFs: Revisiting Waters' Artificial Abort
Abstract
One of the most popular techniques to prove adaptive security of identity-based encryptions (IBE) and verifiable random functions (VRF) is the partitioning technique. Currently, there are only two methods to relate the adversary's advantage and runtime
