  • Estimated project duration: 3 years
  • Subsidy programme: Digital Europe Cyber Working Programme

Conditions

Proposals should target activities on the following subjects:

  • Design of digital signature combiners and key encapsulation mechanism combiners.
  • The testing of the deployment of certificates in protocols that use those certificates.
  • The development of novel protocols for Automatic Certificate Management and revocation, and novel protocols for (privacy-friendly) certificate transparency.
  • The development of methods and tools that experts across various PKI domains can use, including all aspects of key management of asymmetric systems.
