Workpackage 5

Privacy-preserving protocols

The objective of this work package is to develop a couple of specific cryptographic protocols, where the cryptographic systems used are based on lattices. Known solutions exist, but they use other types of cryptographic systems, which are not quantum safe. The protocols developed in this work package will use building blocks as produced in work package 4. Within each of the first three tasks, a specific cryptographic protocol will be developed, namely anonymous credentials, electronic cash, and e-democracy. Implementations of this work package will be used in work package 6.
