§ 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
