The functorial structure of type constructors is the foundation for many definition and proof principles in higher-order logic (HOL). For example, inductive and coinductive datatypes can be built modularly from bounded natural functors (BNFs), a clas

Machine-checked proofs of security are important to increase the rigour of provable security. In this work we present a formalised theory of two fundamental two party cryptographic primitives: $$\varSigma $$ Σ -protocols and Commitment Schemes. $$\v

Game-based proofs are a well-established paradigm for structuring security arguments and simplifying their understanding. We present a novel framework, CryptHOL, for rigorous game-based proofs that is supported by mechanical theorem proving. CryptHOL

Proofs in simulation-based frameworks have the greatest rigor when they are machine checked. But the level of details in these proofs surpasses what the formal-methods community can handle with existing tools. Existing formal results consider streaml

We consider the problem of formally verifying an algorithm in a proof assistant and generating efficient code. Reasoning about correctness is best done at an abstract level, but efficiency of the generated code often requires complicated data structu

This article presents JinjaThreads, a unified, type-safe model of multithreaded Java source code and bytecode formalised in the proof assistant Isabelle/HOL. The semantics strictly separates sequential aspects from multithreading features like locks,

Computer-aided cryptography increases the rigour of cryptographic proofs by mechanizing their verification. Existing tools focus mainly on game-based proofs, and efforts to formalize composable frameworks such as Universal Composability have met with

The notion of a monad cannot be expressed within higher-order logic (HOL) due to type system restrictions. I show that if a monad is restricted to values of a fixed type, this notion can be formalised in HOL. Based on this idea, I develop a library o

Cardinality estimators like HyperLogLog are sketching algorithms that estimate the number of distinct elements in a large multiset. Their use in privacy-sensitive contexts raises the question of whether they leak private information. In particular, c
