Siemens issues digital certificates ("certificates", also known as "Digital IDs") to its employees and agents, known business partners and to Siemens web sites in accordance with its Public Key Infrastructure Disclosure Statement.

Siemens has set up a Public Key Infrastructure (PKI) to issue certificates, with rules for ascertaining and checking the identity of the person or server in question. A Certification Authority then confirms this identity by appending its digital signature at the bottom of the certificate for the person or server.

Siemens Public Key Infrastructure ("PKI") basic documents are available upon request, as necessary and appropriate, from the contact office referred to in the "Public Key Infrastructure Disclosure Statement"
