Abstract
A chemical sensor (11) of a portable electronic device (1) is authenticated by reading a cryptographic sensor identifier from a memory of the chemical sensor and transmitting sensor-related data from the portable electronic device to a remote evaluation unit (6), the sensor-related data comprising the cryptographic sensor identifier. The sensor-related data may be transmitted in encrypted form. The sensor-related data may be complemented with a device identifier for the portable electronic device.
