Danish Digital Signature (OCES)
OCES – Offentlige Certifikater til Elektroniske Services (Public Certificates for Electronic Services) is an establishment of digital signatures. A digital signature is based on a PKI (Public Key Infrastructure). This is an infrastructure which enables authentication and confidentiality in electronic communication between two parties.
OCES is primarily used in communications between private enterprises and public authorities in Denmark. The digital signatures are partly free of charge for the private enterprises, but there is a transaction-fee for merchants who use the infrastructure.
