2.7 Security concept, Bluetooth operation
Sensor adjustment via Bluetooth is based on a multi-stage security
concept.
Authentication
When starting Bluetooth communication, an authentication is carried
out between sensor and adjustment device by means of the sensor
PIN. The sensor PIN is part of the respective sensor and must be
entered in the adjustment device (smartphone/tablet). To increase
adjustment convenience, this PIN is stored in the adjustment device.
This process is secured via an algorithm acc. to standard SHA 256.
Protection against incorrect entries
In case of multiple incorrect PIN entries in the adjustment device,
further entries are possible only after a certain amount of time has
passed.
Encrypted Bluetooth communication
The sensor PIN as well as the sensor data are transmitted encrypted
between sensor and adjustment device according to Bluetooth
standard 4.0.
ModificationofthedefaultsensorPIN
Authentication by means of the sensor PIN is only possible after the
default sensor PIN "0000" has been changed in the sensor by the
user.
