Digital ID

A crucial element in transacting business via networks is what is frequently referred to as 'trust': do I know for sure who I am doing business with? Is the transaction binding? Are my business relationships secure and confidential? 

Siemens issues certificates (known as digital IDs) for employees and for Siemens Web sites. These identify a person or server unequivocally and unambiguously, and comply with ITU Standard X.509V3.

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.

If you receive a Siemens certificate electronically, e.g. by e-mail, and want to check its authenticity, simply compare the signature on the certificate you received with the original signature of the Siemens Certification Authority.
