The Story

Functional Encryption (FE) is a new cryptographic paradigm that overcomes the all-or-nothing decryptability barrier of present encryption systems. In an FE system the decryptor deciphers a function over the message plaintext instead of the message itself.  An application of functional encryption is Identity Based Encryption (IBE) which is ideal to solve key management issues. Or Attribute based Encryption (ABE) that allows a finer-grained decryption policy. Or Inner Product Encryption (IPE) facilitating the computation of affine functions.

Loosely speaking, FE may be seen as the non-interactive version of multi-party computation (MPC). Functional encryption has numerous applications in the field of privacy-preserving computation including private AI and business analytics.

Make Functional Encryption the new Encryption Standard!

To ease the deployment of functional encryption technologies, two APIsI - CiFEr (C) and GoFE (Go lang) - have been developed within the EU H2020 project FENTEC so that non-specialist may leverage the power of many state-of-the-art FE schemes. With this hackathon, we want to show the practicability and versatility of FE and reduce the entry barrier for researchers, engineers, product owners, architects to deploy FE in their solutions, ranging from prototypes to enterprise-ready products.

Challenges

Against this background the hackathon projects focus on one of the following challenges:

Extend

Extend the CiFEr or GoFE API with additional arithmetics, schemes and protocols.

Improve

Do whatever it takes to improve the usability and ease-of-use to make the APIs accessible to the broadest audience possible.

Examples include video tutorials, coding examples, wikis, documentations, dockerization, etc.

Apply

Demonstrate a viable application of FE, for example, in the use case of access control or privacy-preserving AI.

Surprise

This challenge statement leaves it open to come up with any idea that demonstrates the magic of FE with help of the APIs.

Judging Criteria

At this hackathon, we believe in spreading positivity. Therefore, we will be awarding five prizes.

Technical Execution

• How has the team effectively utilized the FE technologies?
• How easy is the application to use?
• How advanced is the prototype presented?
• Is there a working demo?

Challenge Fit

• How relevant is the project to the stated challenge?

Impact

• Will this solution have a far reach and market potential?

Agenda

The hackathon consists of three stages:

Intro Workshop(Fri 8th Jan)

We will give an introduction to functional encryption for a broad audience ranging from theoreticians to practitioners. It is also a good entry for newbies. No prior knowledge on FE is necessary. The goal of the invited talks will be to introduce the theory, applications and limitations of functional encryption. We will also explain the FE API developed in the H2020 FENTEC project that allows participants to implement novel use cases leveraging the functional encryption paradigm. Towards the end of the talks we will announce some challenges to attendees along the opportunity to win prizes.

Hackathon (Sat 9th to Thur 14th Jan)

Attendees may team up in order to work on the challenges. Mentors both from academia and industry will help attendees with questions regarding the theory of functional encryption, the deployment of the API, or the identification of meaningful use cases.

Demo Day (Fri 15th Jan)

Teams will give a short presentation (10-15min) of their results. A jury will pick the winners.
