  §  90.553   Encryption.

   (a) Encryption is permitted on all but the two nationwide
   Interoperability calling channels. Radios employing encryption must
   have a readily accessible switch or other readily accessible control
   that permits the radio user to disable encryption.

   (b) If encryption is employed, then transmitters manufactured after
   August 11, 2014 must use the Advanced Encryption Standard (AES)
   specified in ANSI/TIA-102.AAAD-A: Project 25 Digital Land Mobile
   Radio-Block Encryption Protocol, approved August 20, 2009. Until 2030,
   manufacturers may also include the Digital Encryption Standard (DES) or
   Triple Data Encryption Algorithm (TDEA), in addition to but not in
   place of AES, for compatibility with legacy radios that lack AES
   capability. The Director of the Federal Register approves this
   incorporation by reference in accordance with 5 U.S.C. 552(a) and 1 CFR
   part 51. The standard can also be purchased from TIA/EIA, 2500 Wilson
