Traq: Estimating the Quantum Cost of Classical ProgramsPLanQC 20262026-01-12
Traq provides an automated pipeline that compiles a classical CPL source language to unitary quantum code, extracts three cost functions (worst-case have cost…
Talk on
Decompiling for Constant-Time AnalysisPriSC 20262026-01-11
Claims that mainstream decompilers can hide timing leaks by turning branches into conditional moves, tests five popular decompilers and finds unsoundness for…
Talk on
Preservation of Speculative Constant-time by CompilationPriSC 2025 (with POPL 2025)2025-01-20
Shows that common compilers (GCC -O0 and -O1 and Jasmin) produce speculatively insecure binaries from speculatively constant-time sources, then builds a…
Talk on
Preservation of speculative constant-time by compilationPOPL 20252025-01-19
Shows that mainstream compilers (GCC -O0/-O1 and Jasmin) can break speculative constant-time by removing or introducing Spectre-v1 leaks, gives concrete…
Talk on
Automating equational proofs in Dirac notationPOPL 20252025-01-19
Proves that Dirac notation’s first-order theory is decidable by reducing formulas to the theory of real closed fields (Tarski) and shows practical equivalence…
Talk on
A quantitative probabilistic relational Hoare logicPOPL 20252025-01-19
eRHL is a program logic whose pre/post-conditions are nonnegative real-valued functions on pairs of states, and it gives upper bounds on expectations…
Talk on
Hopping Proofs of Expectation-Based Properties: Applications to Skiplists and Security(…)OOPSLA 20242024-10-20
Proposes a EHL + pRHL hopping rule that reduces expectation-based proof goals to related programs, implements it inside EasyCrypt integration, and proves…
Talk on
A modal type-theory of expected cost in higher-order probabilistic programsOOPSLA 20242024-10-20
pλ-amor is a graded modal type theory that encodes probabilities, potentials and expected cost at the type level and proves bounds for higher-order…
Talk on
Decision and Complexity of Dolev-Yao HyperpropertiesPOPL 20242024-01-14
Provides the first decision procedure for Dolev–Yao hyperproperties under a bounded number of sessions and subterm-convergent equational theories, proving…
Talk on
CoqQ: Foundational Verification of Quantum ProgramsPOPL 20232023-01-15
CoqQ is a Coq framework that formalizes a quantum language, proves a program logic sound with respect to a denotational semantics built on MathComp and…
Talk on
Safe Couplings: Coupled Refinement TypesICFP 20222022-09-11
Enhances refinement types with a coupling-based connective that captures relational properties like expected sensitivity and proves that output-distance is…
Talk on
On Feller Continuity and Full AbstractionICFP 20222022-09-11
Shows that in a call-by-value higher-order lambda calculus with sampling and only continuous real-valued primitives, Feller-continuity on the induced labelled…
Talk
A Pre-Expectation Calculus for Probabilistic SensitivityPOPL 20212021-01-17
A relational pre-expectation calculus gives computable upper bounds on the Kantorovich lifting of output distributions, proved sound and (in cases) continuous…
Talk on
Deciding Accuracy of Differential Privacy SchemesPOPL 20212021-01-17
Introduces accuracy as a parametric notion based on distance to disagreement (dd) and output closeness γ, yielding an explicit alpha–beta–gamma claim: e.g. for…
Talk on
Verifying Constant-Time ImplementationsUSENIX Security '162016-08-10
Claims an automated verifier, ct-verif, that proves constant-time for optimized LLVM code by reducing the two-execution security property to safety of a…
