Camille Nuoskala from Tampere University (TUNI) presented HARPOCRATES research at the 29th ACM Symposium on Access Control Models and Technologies (SACMAT 2024), held on 15–17 May 2024 in San Antonio, Texas, USA. The paper was presented in person.
SACMAT is a leading symposium on access control, security, and trust models, bringing together academics and practitioners to discuss advances that shape secure information systems.
Research Contribution
Camille Nuoskala presented the paper:
“FE[r]Chain: Enforcing Fairness in Blockchain Data Exchanges Through Verifiable Functional Encryption.”
The work introduces FE[r]Chain, a framework that combines blockchain technologies with verifiable functional encryption (VFE) to ensure fairness in data exchanges. Traditional blockchain-based data sharing can face challenges with accountability and fairness, particularly in ensuring that all parties adhere to agreed rules. FE[r]Chain integrates advanced cryptographic methods to provide verifiable guarantees, ensuring that sensitive data remains confidential while fairness is enforced transparently.
Connection to HARPOCRATES
The HARPOCRATES project develops privacy-preserving cryptographic solutions that can be applied in areas where secure and trustworthy data use is essential. FE[r]Chain is an example of how functional encryption can extend beyond privacy to address fairness and accountability, contributing to the broader project goal of enabling secure, resilient, and transparent digital infrastructures.
