Frederik Vercauteren
Cybersecurity & Privacy Innovation Forum

• Project funded by EU in Horizon 2020.
• Starting date 1st January 2015, runs for 3 years.
• 7 partners from academia and industry, KU Leuven is
coordinator
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 2

• Homomorphic encryption:
• Process sensitive data in encrypted form
• Without decrypting it!
• Somewhat vs. Fully homomorphic encryption
• Somewhat: can compute functions of limited complexity
• Fully: can compute any function
• Applicability of SHE in 3 use cases:
• Smart grid
• Automated detection of crime
• Shared satellite infrastructure applications
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 3

1. Open source toolbox for SHE in SW and HW
2. Security analysis & parameter recommendations
3. Focus on real world applications with immediate
impact
4. Enable knowledge transfer and exploitation
5. Improve European competitiveness in
homomorphic cryptography
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 4

1. Use case specification/requirement analysis (NXP)
2. Scheme design and security analysis (UL)
3. Open source implementation of SHE libraries (CRX)
4. Demonstrators and integration (Thales UK)
5. Dissemination, standardization, exploitation and
training (UNIVBRIS)
6. Project management (KU Leuven)
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 5

• Satellite use case:
• GMES earth observation satellites
• Encrypted image data and positioning data
• Smart grid use case:
• Non-linear billing and advanced statistics
• Automated detection of organized crime
• Encrypted version of crime detection algorithms
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 6

• Optimize schemes for speed and size
• Currently large keys and therefore slow
• Design new schemes based on different hard problems
• Design SHE-friendly symmetric ciphers
• Hybrid approach to keep message expansion to
minimum
• Security analysis
• Parameter recommendations
• Currently not really studied in depth
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 7

• Software implementations:
• Target different platforms
• Open source with standardized API
• Hardware implementations:
• Evaluate low depth circuits on FPGA
• SW/HW co-design in embedded environment
• Cryptanalytic implementations
• Understand precise security level of SHE
• Specify security parameters
29 April, 2015 HEAT – Homomorphic Encryption Applications and Technology 8

• Open source SW and HW libraries for SHE
• Develop your own applications
• Faster, more compact SHE systems
• Security parameter recommendations
• Attend summer school and work shops
