Kripke Models, Distributive Lattices, and Medvedev Degrees
We define a variant of the standard Kripke semantics for intuitionistic logic, motivated by the connection between constructive logic and the Medvedev lattice. We show that while...

EON: modeling and analyzing dynamic access control systems with logic programs
We present EON, a logic-programming language and tool that can be used to model and analyze dynamic access control systems. Our language extends Datalog with some carefully design...

CCA2 Secure IBE: Standard Model Efficiency through Authenticated Symmetric Encryption
We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performan...

Models of real-valued measurability
Abstract. Solovay's random-real forcing ([1]) is the standard way of producing real-valued measurable cardinals. Following questions of Fremlin, by giving a new construction, ...

A Concurrent Model for Linear Logic
We build a realizability model for linear logic using a name-passing process calculus. The construction is based on testing semantics for processes, drawing ideas from spatial and...
