Idealized Algol with Ground Recursion, and DPDA Equivalence
Abstract. We prove that observational equivalence of IA3 + Y0 (3rdorder Idealized Algol with 0th-order recursion) is equivalent to the DPDA Equivalence Problem, and hence decidable...

Basing Cryptographic Protocols on Tamper-Evident Seals
Abstract. In this paper we attempt to formally study two very intuitive physical models: sealed envelopes and locked boxes, often used as illustrations for common cryptographic ope...

Discrete Random Variables over Domains
In this paper we initiate the study of discrete random variables over domains. Our work is inspired by work of Daniele Varacca, who devised indexed valuations as models of probabi...

Quantum Complexity of Testing Group Commutativity
We consider the problem of testing the commutativity of a black-box group specified by its k generators. The complexity (in terms of k) of this problem was first considered by Pa...
