SignalFire New Firmware Adds AES-128 Encryption to its Wireless Remote Monitoring Product Line For Added Security

Wireless monitoring and control systems must ensure the security of data as it passes from device to device.

To provide this high level of data integrity for customers’ critical processes, SignalFire Wireless Telemetry has released a new version of their firmware that includes a suite of advanced security features including:

• AES-128 Encryption supports a more reliable and secure wireless network infrastructure within all its communication systems. The encryption protects against tampering as any modified data is invalidated and ignored.

• Device Authentication ensures that nodes perform an integrity check before joining the network.  This prevents nodes from joining a rogue or malicious network that would prevent them from communicating with their intended network.  Additionally, this process also allows only authenticated nodes to join the network.

• Replay Prevention stops messages from being resent by a malicious device.  It blocks security attacks if packets are captured and retransmitted at a later time.  For example, if a message to turn on a relay is captured and sent later, operations could be at risk. SignalFire’s replay prevention scheme is based on time synchronization of all nodes in the network and would not allow this message to be accepted by the network.  

The new firmware is now shipping on all SignalFire products as of August 1, 2016.  It is also available via the SignalFire ToolKit’s automatic firmware download feature.  For more information about SignalFire Wireless security, refer to  or contact the company at [email protected] or 978-212-2868.
