USER_KEY 

 
Each STM 550 module is pre-programmed at the factory with a randomly generated 128 bit 
security key (FACTORY_KEY). This key will by default be used to encrypt and authenticate 
STM 550 radio telegrams when operating in high security mode. 
 
In certain applications it might be desirable to assign a different (user-defined) security key 
(USER_KEY) during commissioning to STM 550. This can be done by writing the user-de-
fined security key to the USER_KEY register and setting KEY SELECTION field of the SECU-
RITY_KEY_MODE to 0b01 as described below.  
 
Note that the USER_SECURITY_KEY register is a write-only register meaning that it is not 
possible to read back a user-defined security key. 

 

SECURITY_KEY_MODE 

 
The register SECURITY_KEY_MODE allows selecting if FACTORY_KEY or USER_KEY should 
be used to encrypt and authenticate STM 550 radio telegrams in high security mode. In ad-
dition, it allows disabling the transmission of Secure Teach-in telegrams in order to protect-
ing the security key.  
 
Note that if the transmission of a secure teach-in telegram has been disabled and is subse-
quently re-enabled then USER_KEY will be reset to FACTORY_KEY.  
 
Figure 4 below shows the structure of the SECURITY_KEY_MODE register.
