This repository contains the implementation of the CONFidentiality EnforcemenT TransparencY (CONFETTY) tool submitted to the Forum Track of the 38th International Conference on Advanced Information Systems Engineering (CAiSE'26).
CONFETTY is a prototypical blockchain-based process-aware information system preserving the confidentiality of exchanged information while maintaining public enforcement and transparency of process execution. CONFETTY employs smart contracts to encode and enforce business process logic while logging interactions between parties. It resorts to Multi-Authority Attribute-Based Encryption (MA-ABE) to specify the access rights of different parties to activity data payloads and information artifacts, thus safeguarding confidentiality.
Below we present a step-by-step video demonstrating the local execution of CONFETTY.
For detailed documentation and a step-by-step tutorial on how to configure and test CONFETTY locally, check out the Wiki.
This repository contains several folders necessary to run the system.
- The Confidentiality Manager folder contains all the files required to run the Confidentiality Manager.
- The Evaluation tool folder contains the tool used to run all the tests and to produce the ``Execution Analysis'' presented in this paper.
- The Performance Analysis folder contains all the images from the tests performed, together with their cost and time tables.
- The Process Manager folder contains the files needed to run the Process Manager.
- The Running example files folder contains the two files used as inputs for the running example in the papers (an X-ray BPMN choreography), as well as the references to the deployed smart contracts where all the transactions can be found.
