Verifying Implementations of Security Protocols by Refinement

Type-checking Implementations of Protocols Based on Zero-knowledge Proofs – Work in Progress –

We present the first static analysis technique for verifying implementations of cryptographic protocols based on zero-knowledge proofs. Protocols are implemented in RCF∧∨, a core calculus of ML with support for concurrency. Cryptographic primitives are considered as fully reliable building blocks and represented symbolically using a sealing mechanism. Zero-knowledge proofs, in particular, are s...

Union, intersection, and refinement types and reasoning about type disjointness for security protocol analysis

In this thesis we present two new type systems for verifying the security of cryptographic protocol models expressed in a spi-calculus and, respectively, of protocol implementations expressed in a concurrent lambda calculus. The two type systems combine prior work on refinement types with union and intersection types and with the novel ability to reason statically about the disjointness of type...

Manual for Slede Annotation Language

Verifying sensor network security protocol implementations using testing/simulation might leave some flaws undetected. Formal verification techniques have been very successful in detecting faults in security protocol specifications; however, they generally require building a formal description (model) of the protocol. Building accurate models is hard, thus hindering the application of formal ve...

Union, intersection and refinement types and reasoning about type disjointness for secure protocol implementations

We present a new type system for verifying the security of reference implementations of cryptographic protocols written in a core functional programming language. The type system combines prior work on refinement types, with union, intersection, and polymorphic types, and with the novel ability to reason statically about the disjointness of types. The increased expressivity enables the analysis...
