Abstract

the invention relates to a computer-implemented method for providing a digital certificate to a device. The method is based on receiving, from the device, authentication data via a secure communication channel. Furthermore, the method is based on receiving, from the device, or determining, by the server, a first certificate identifier. In particular, the first certificate identifier is a hash value. Further steps of the method are verifying the authentication data and receiving, from the device, a first public key created by the device.The method is furthermore based on sending a first certificate signing request related to a first domain name based on the first public key to a certificate authority. Herein, the first domain name comprises the certificate identifier, and a domain related to the first domain name is controlled by the server. In particular, the first domain name is a wildcard domain.The method is furthermore based on receiving the first digital certificate from the certificate authority, wherein the first digital certificate is a wildcard certificate based on the first domain name and the first public key signed by the certificate authority, providing the first digital certificate to the device.
