CAPSULE: Applied Cryptography and Cryptographic implementation Security

CAPSULE’s research activities are organized along four axes, namely symmetric-key cryptography, post-quantum cryptography, security of cryptographic hardware and software implementations, and the real-world cryptographic systems.

Research themes

• Design and analysis of ciphers: lightweight block ciphers, authenticated encryption schemes, etc ;
• Lattice-based cryptography, security proofs and advanced constructions, deployment of post-quantum standards ;
• Security of cryptographic implementations: side-channel attacks, micro-architectural attacks and countermeasures ;
• Design and analysis of real-world cryptographic systems such as WhatsApp and Signal secure messaging or database security with Searchable Symmetric Encryption Schemes.
