PKI is an abbreviation and stands for public key infrastructure. It is an important component of a solid security concept and describes a cryptographic trust anchor. Within this framework, every device and every user must identify themselves. Only with successful authentication is it then possible to enable secure communication or connection between two endpoints.
The concept's security mechanisms provide greater security between digital and physical resources. To enable secure communication between people, devices and software, they must create and manage trusted electronic identities. These identities include people, services as well as objects.
The foundation of PKI is hardware, policies, standards and software. Without a combination of these elements, it would not be possible to create a digital PKI certificate. Let alone distribute, manage or even revoke it. Finally, the PKI guarantees that a digital certificate is trustworthy. For this reason, it is characterized by different features.
The digital certificate is composed of various data such as a serial number and other identifying information. In most cases, it is based on the X509 standard. This uniquely assigns a public key to an application, a device or a person.
While the public key is known, only its owner knows the private key. This ensures that the person, system or device can identify itself uniquely. Both keys are created as a pair and mathematically linked.
The combination of a public digital certificate and a private key is also known as eID. Thanks to the PKI infrastructure, the ensemble of certificate and private key functions like a digital ID card. It therefore makes it possible to prove one's own identity.
Because PKI manages electronic identities for people, devices, and services, it allows strong authentication, data encryption, and digital signatures.
The basis for this system is the combination of a public and a private key. With the help of these keys, the PKI infrastructure checks whether communication with other devices is possible, for example. In concrete terms, this means that the PKI verifies the identity of the owner. After the check, it issues a certificate for the respective public key, thereby certifying the authenticity of the key pair. The authenticity of a certificate can also be verified in this way.
We have developed an effective and comprehensive format for verifiable security that can be integrated directly into your website. This certificate proves to third parties such as customers or insurance companies a high level of security, data protection and IT security awareness.
The certificates we issue prove a high level of IT security at a given time according to a standard or individual test modules. Depending on the assessment, different test guidelines are chosen and evaluated.

Video-Ident - also spelled Videoident - is a convenient alternative to the PostIdent procedure you know from the post office. It is used to establish identity and is intended to prevent money laundering and fraud.
