PKI and key management

Security with keys and certificate

PKI and key management allows building trusted IT infrastructures and guarantee secure communication in highly networked systems. Reliable authentication as well as signing and encryption of data are mandatory for maximum IT security.
Public key infrastructures (PKI) allow to issue, manage and verify digital identities in a secure way.

The ECOS TrustManagementAppliance is a PKI and key management solution securing mobile devices, PCs, servers, processes and other devices in the (I)IoT area.
