UART Serial Port Module includes WLAN security feature.

Press Release Summary:

For mission critical applications, OWS451 WLAN UART Serial Port Module is supplied with Extensible Authentication Protocol-Transport Layer Security. With EAP-TLS, each wireless client is assigned unique authentication certificate. EAP-TLS makes it possible to centrally manage individual units when one would like to centrally remove certain client's certificate. With client-side certificate, security is also sustained as compromised password is not enough to break into EAP-TLS-enabled systems.

connectBlue Releases New WLAN Security Feature

Today, connectBlue® made available the Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) as a Wireless LAN (WLAN) security feature. EAP-TLS is particularly beneficial in mission critical applications when there is a need to increase security and / or to centrally authorize individual wireless units.

In small embedded systems, WLAN security features applied are usually various forms of encryption such as WPA-PSK, WPA2-PSK. Typically, the assigned authentication key is the same for all distributed wireless units. However, with EAP-TLS, each wireless client is assigned a unique authentication certificate.

“Applying EAP-TLS in small embedded systems is unusual as it is mostly seen in large, complicated systems. But since a key component of the connectBlue delivery is a repeatedly robust wireless experience, we have put extensive resources into applying the EAP-TLS security feature,” says Rolf Nilsson, CEO of connectBlue. “Now, also mobile or portable WLAN applications can enjoy real-time handover as well as disturbance-free roaming.”

New connectBlue WLAN UART Serial Port Module OWS451s are shipped with the added-on EAP-TLS feature whereas customers who have installed OWS451 modules can easily download upgrade firmware from the connectBlue support site. The OWS451 EAP-TLS feature has already been tested and validated in key mission critical applications.

EAP-TLS is considered as one of the most secure standards and is thus often required by central IT management. For instance, EAP-TLS makes it possible to centrally manage individual units when one, for example, would like to centrally revoke a certain client’s certificate. Thanks to the client-side certificate, security is also sustained as a compromised password is not enough to break into EAP-TLS enabled systems as the potential intruder would also need the client-side private key. Both these advantages make EAP-TLS particularly beneficial in demanding factory automation and medical installations.
