Project description
Lattice-based cryptography leveraging attribute-based encryption
As data are increasingly stored in the cloud and processed using shared infrastructure to accommodate data volumes and resource-intensive computations, security, privacy and compliance with legal regulations are increasingly difficult to ensure. Furthermore, the advent of quantum computing is making older encryption paradigms obsolete. With the support of the Marie Skłodowska-Curie Actions programme, the ACryL project aims to develop new techniques relying on advanced cryptographic primitives in the context of lattice-based cryptography. Specifically, ‘succinct non-interactive arguments of knowledge’ enable end users to verify that outsourced computations were correctly performed. Attribute-based encryption (ABE) enables selective data sharing while preserving confidentiality. Lattice-based assumptions will allow construction of ABE for general circuits and security even with quantum computers.
Objective
As organizations increasingly rely on cloud services and shared infrastructures to store data and delegate resource-intensive computations, it is essential for maintaining privacy, security, and compliance with regulations to i) protect data while ensuring that only authorized individuals or systems can decrypt and use it, and ii) guarantee the correctness of the computation performed by cloud services.
Advanced cryptographic primitives tackle both of these challenges: on the one hand, attribute-based encryption (ABE) effectively addresses the problem of selective data sharing while preserving confidentiality of unauthorized messages, on the other hand, succinct arguments (SNARKs) enable end users to verify efficiently that outsourced computation was performed correctly by cloud providers.
In recent years, both ABE and SNARKs have seen tremendous research progress, especially in the context of lattice-based cryptography, where both constructions often rely on shared techniques, underscoring the deep synergy between these two cryptographic primitives.
Leveraging lattice-based assumption offers several key advantages in this context, which are essential to the proposed project, in particular, enabling the construction of ABE for general circuits, and providing post-quantum security, meaning these constructions are believed to remain secure even in the presence of quantum computers.
By exploring and developing new techniques that leverage these synergies, this project aims to advance theory and practice in both domains and construct robust, quantum-secure cryptographic systems that address the complex security and privacy challenges of the digital age.
