Motorola is a US-based manufacturer of electronic equipment. The company was founded in 1928 by Paul Galvin and started in Chicago (Illinois, USA) as Galvin Manufacturing Corporation. The first product was a battery-eliminator for using radio receivers in automobiles. In 1930, the company name was changed to Motorola, after that name had been acquired from William Lear. A few years later they started using the Motorola brand name as a trademark. The 'bat' symbol is from 1955.

Known Motorola encryption algorithms
  1. REX is a diminutive of Range Extension. It is a technique which converts a 1-bit CTAK block cipher into a kind of counter addressing mode, and is described in US Patent 4,893,339 [5].

Key loaders
Most Motorola devices that provide some level of encryption, are protected by means of a crypto­graphic key that has to be entered into the device, either manually or with a so-called key loader. In Motorola terminology, a key loader was known as a code inserter or a key variable loader. The following key loaders are known:

  1. First generation.
  2. Only 2 algorithms can be supported smultaneously. Each algorithm has to be ordered separately from Motorola. Upgrades for the KVL-3000 are not longer available. Check before buying.
  3. Each algorithm has to be ordered separately, so there is no guarantee that they are already loaded when you buy one. This version does not support the old DVP format.
  4. Used with the SE-160 and SE-660 mobile radios developed by ASCOM.
