Transport Layer Security 1.0 handshake protocol formal verification case study: How to use a proof script generator for existing large proof scores [PDF]
PeerJ Computer Science, 2023 The Transport Layer Security (TLS) 1.0 protocol has been formally verified with CafeInMaude Proof Generator (CiMPG) and Proof Assistant (CiMPA), where CafeInMaude is the second major implementation of CafeOBJ, a direct successor of OBJ3, a canonical ...

Using CafeOBJ to Mechanise Refactoring Proofs and Application [PDF]
Electronic Notes in Theoretical Computer Science, 2007 AbstractIn this paper we show how rewriting systems, in particular CafeOBJ, can be used to automatically prove refactoring rules. In addition, a small case study that illustrates the application of a refactoring rule in an arbitrary program is also developed. Our approach is based on a sequential object-oriented language of refinement (rool) similar to

Advances of proof scores in CafeOBJ
Science of Computer Programming, 2022 Critical flaws continue to exist at the level of domain, requirement, and/or design specification, and specification verification (i.e., to check whether a specification has desirable properties) is still one of the most important challenges in software/system engineering.

An integrated tool set for verifying CafeOBJ specifications [PDF]
Journal of Systems and Software, 2022 CafeOBJ is a language for specifying and verifying a wide variety of software and/or hardware systems. Traditionally, verification has been carried out via proof scores, which consist of reducing goalrelated terms in user-defined modules. Although proof scores are semi-formal (the specifier is partially responsible for soundness), their flexibility ...

An Integration of CafeOBJ into Full Maude [PDF]
Lecture Notes in Computer Science, 2014 We present in this paper an integration of CafeOBJ into Full Maude. We have developed a grammar to parse any CafeOBJ specification, an intermediate language to store it, and a translation from this representation into Maude specifications. This integration enhances CafeOBJ functionality in many ways: our intermediate representation has been developed ...

Trace anonymity in the OTS/CafeOBJ method
2008 8th IEEE International Conference on Computer and Information Technology, 2008 We report on a case study in which the OTS/CafeOBJ method is used to formalize and verify trace anonymity property of distributed systems. In this case study, the property of trace anonymity is formalized with the trace notations of observational transition systems (OTSs), and CafeOBJ language/system is used as an interactive theorem prover to verify ...

Simulation-Based Invariant Verification Technique for the OTS/CafeOBJ Method
IEEE Access, 2021 We demonstrate the power of the simulation-based invariant verification technique through two case studies in which it is formally verified that two mutual exclusion protocols, MCS protocol and Anderson protocol, enjoy the mutual exclusion property by ...

Parchments for CafeOBJ Logics [PDF]
, 2014 This paper addresses issues arising in the systematic construction of large logical systems. We rely on a model-theoretic view of logical systems, captured by institutions that are in turn presented by parchments. We define their categories, and study constructions that may be carried out in these categories.
