Open source IoT X509 certificate management

Open source IoT X509 certificate management

Zibawa has now launched open source software for creating your own public key infrastructure for IoT devices.

The software is designed to allow user devices to request,download and automatically renew X509 client certificates, taking the headache out of device password management.  The system administration panel allows administrators to approve initial requests, and if necessary revoke certificates.

Many common IoT software such as mosquitto or rabbitMQ offer the option to use X509 certificates in place of usernames and passwords, but although a more robust solution, is often not used due to the complexities of managing certificate renewal.  The Zibawa software enables manufacturers and maintainers of IoT devices to deploy devices with identical firmware code.  When a device is deployed, it will request a certificate from the IoT_pki backend (which initially must be approved by the system administrator).  From then on, the same firmware can renew certificates as often as necessary without the need for human interaction.

Below shown the admin screens for approving certificate requests, or for revoking certificates.

 

 

A test python client is also available which downloads and renews an example X509 certificate to your PC.

The software is freely available on GitHub.  https://github.com/zibawa/IoT_pki

 

Drones – Leading the way in open IoT innovation

Drones – Leading the way in open IoT innovation

March brought the Drone Show to Barcelona, where many new companies are bringing their expertise in aerial surveillance to a wide range of industrial applications.  Early adopters are in agriculture, and industrial infrastructure monitoring.   As technological startups, many of these companies are preparing to adopt new technologies such as IoT to support their data collection and processing, and Zibawa is proud to be part of this innovative ecosystem.

Advanced Factories Conference Barcelona

Zibawa assisted  the advanced manufacturing conference in Barcelona, where a number of manufacturers are show casing their offers for Industrie 4.0.  While the benefits of connected machinery are clear, the barriers to acceptance appear to be the difficulty in connecting to existing machinery and compatibility issues.   While many of the big manufacturers are recognizing the merits of open source, many are now claiming that there systems are “open” since they are offering developers the possibility to sell “apps” based on their systems.    However we recommend that end users ensure that they install systems which are truly modular and open, to ensure that they remain in control of their data  and can grow and evolve their systems as new technology emerges.
