ARMER Encryption

ARMER supports a variety of encryption algorithms including AES (Advanced Encryption Standard) and DES-OFB (Data Encryption Standard-Output Feedback).  Each of these algorithms is commonplace on ARMER.

Entities purchasing radios for use on encrypted ARMER talkgroups are encouraged to purchase radios with AES and DES-OFB functionality; as well, they should purchase “multi-key” capability so that the encrypted radio may access more than one encryption key.  SAFECOM and the Minnesota Statewide Emergency Communications Board (SECB) have declared that grant money may not be used to purchase encryption-enabled radios unless AES encryption is included.  

There is no standard requiring that entities use encryption on ARMER or that entities monitor encrypted talkgroup but several statewide, regional, and local ARMER tactical talkgroups and an increasing-number of local dispatch talkgroups are encrypted.  A properly-programed, encryption-capable radio and applicable permissions are necessary to monitor or use those talkgroups.
