Bluetooth® security technology
A secure low energy technology for the process industry developed by Endress+Hauser
Convenient wireless access to field instruments is of increasing interest. Significant security risks emerge with the growing frequency with which instruments are accessed remotely. Developments in the Industrial Internet of Things are leading to interconnected process control components. Endress+Hauser has developed a security layer for Bluetooth® that protects the passwords, using CPace as its core-component. With CPace, the notorious attacks on the Bluetooth® pairing-step are prevented.
Bluetooth® security matters
Secure password-based user authentication plays a special role today, particularly when devices with wireless interfaces such as Bluetooth® are involved. As it is extremely difficult to protect passwords, Endress+Hauser's CPace uses a powerful PAKE technique that was derived from the PACE method used in German ID cards. With CPace, Bluetooth® connections are always secure, no matter the password length.

Bluetooth® security by Endress+Hauser is recommended by IETF
In 2020 CFRG, the Crypto Forum Research Group of the Internet standardization body IETF, chose the Endress+Hauser in-house solution CPace as winner (“Recommended for use in internet protocols”) as the result of a comprehensive security analysis. And independently, in 2016, the Munich-based Fraunhofer Institute AISEC classified the protection level of the Endress+Hauser Bluetooth® security extension as “high”.
