Secure IoT with PKI-based identities

For any IoT application, it is crucial to protect data, user privacy, and safety. Breaches can harm production continuity and business processes, customers’ trust, and – worst of all – human health and life.

To enable true end-to-end security and prevent cyber attacks against IoT applications, a public-key infrastructure (PKI) can be used to issue certificate-based identities. These trusted identities secure the IoT applications with strong authentication of devices, people and servers, encrypted communication and proven data integrity.

Nexus IoT-How it works

How does it work?

The Smart ID PKI platform issues certificate-based, cryptographically secure and unforgeable identities that enable:

Strong authentication: Certificate-based authentication ensures that only authorized users, devices or servers can connect to a network or application. Revocation of certificates instantly blocks access in case of compromise or emergency.

Encryption and Privacy: Certificates enable encrypted communication between devices and services for secure transmission of data over TLS.

Integrity: Digitally signed messages based on certificates can be used to prove the origin of data, and to detect manipulation of data. Signed firmware enables secure software updates.
