System for appts.-side storage of key pairs based on public key infrastructure (PKI)

摘要

The storage of key pairs, based on PCI, e.g. X509v3 standard is applied in the internet access device (IZV). A key pair is coupled to the IZV non-erasably and non-separably. After user's authentication the key pair is activated for read-out access.A further key pair can be again overwritten and stored in the IZV in a secure process after verification assisted by the first key pair.
