In addition to the normative requirements, it should be noted in the product definition that a higher security level (SL) of a component such as a control system requires fewer protective measures to be taken externally. Since system considerations always require intensive coordination with the end user, embeX advises on the cost-benefit analysis of improved security protection, where further system components and coordination are not necessary.

The certified embeX development process covers both safety and security requirements and is made available to customers for adaptation on request.

On the one hand, synergies are created in the development of safe and secure products, as both areas place high demands on the care taken in development and predictable behaviour. On the other hand, it is necessary to strike a balance between a large number of opposing objectives of the security concepts on a project-specific basis.

KISS: Safe & Secure Platform for the IoT

The networking of functionally safe devices in the IoT environment requires the safeguarding of functional safety through suitable cybersecurity measures. embeX has developed the powerful and field-proven multiprocessor platform KISS for these diverse areas of application - KISS stands for “Keep It Save and Secure”. The platform covers the following core functions of cybersecurity:

• Implementation of access restrictions
• Use of secure and proven protocols
• Updateability of bootloader, operating system, application SW

The technical basis of the KISS multiprocessor platform is a Yocto-based embedded Linux with the following advantages for manufacturers:

• Highly efficient development through integration of modules
• Very large, constantly growing range of functions
• Future-proofing through upcoming advances in the Yocto project

Safety solutions from a wide range of standards (IEC 61508, ISO 13849, MDR, FDA, etc.) can be integrated into the KISS platform to get protected effectively and efficiently with regard to security.

Functional Safety

We are the leading provider of development services in the area functional safety covering measurement, drive, and control technology, medical engineering, for the associated control devices and for components of collaborative robot systems. embeX was the first company worldwide to be awarded the highest maturity level for Functional Safety Management (FSM) according to IEC 61508 by TÜV Rheinland.

embeX develops embedded systems ranging from SIL 1 to SIL 4, from PL a to PL e, from medical device class I to III. We advise and support our customers in all issues relating to functional safety, when implementing a functional safety management system and during assessment and certification.

Our safety experts actively work in the safety standardisation groups such as IEC 61508 (SIL) and maintain constant contact with all renowned notified bodies.
