Sufficient Conditions for Intractability over Black-Box Groups: Generic Lower Bounds for Generalized DL and DH Problems
Abstract. The generic (aka. black-box) group model is a valuable methodology for analyzing the computational hardness of number-theoretic problems used in cryptography. Since the p...

Fast alignment of digital images using a lower bound on an entropy metric
We propose a registration algorithm based on successively refined quantization and an alignment metric derived from a minimal spanning tree entropy estimate. The metric favors edg...

Resolution lower bounds for the weak pigeonhole principle
We prove that any Resolution proof for the weak pigeon hole principle, with n holes and any number of pigeons, is of length (2n ), (for some global constant > 0).
