Frequetly Asked Questios This Voice Security Selectio Guide is desiged to help aswer commo questios about voice scramblers, their applicatios & which level of security is appropriate. Do I eed digital voice ecryptio? Most likely ot! Digital voice ecryptio teds to be very costly ad the beefits for may systems do ot outweigh this high cost. Most users oly eed their coversatios secured for a tactical amout of time (i.e. days or weeks). Oce this time period has passed the iformatio is o loger importat. Examples of this would be a military commader directig troop movemets durig a battle, police SWAT or Narcotics operatios, a taxi or towig compay pickig up a fare, etc. Oce the troops have moved, the SWAT operatio is over or the fare is picked up the iformatio trasmitted is o loger importat to a eavesdropper, therefore most systems oly eed a tactical level of voice security such as Midia s TVS- 2 or VS-1200. Digital voice ecryptio is typically oly eeded to secure coversatios for a strategic time period (i.e. years). Is voice iversio scramblig secure? Voice iversio scramblers will provide voice security to protect coversatios from a casual listeer. May radio maufacturers are buildig voice iversio scramblers ito the firmware of the radio ad they ted to use the same or very similar iversio frequecies. If you buy a radio with the built i iversio scrambler, someoe with a radio with a built i iversio scrambler could eavesdrop o your coversatio if o the same chael. Addig a Midia voice iversio scrambler, such as the VPU-12A or VS-1000, o a iversio frequecy away from what the radio maufacturers have built i ca provide additioal voice security. Is it difficult to istall a voice scrambler? Midia supports plug i modules for may popular radio maufacturers ad models icludig Motorola, Kewood, Vertex, Icom, Tait ad HYT. Midia also offers voice security i a speaker microphoe cofiguratio. May plug i istallatios ca be doe i just a matter of miutes. For radios ot supported with a plug i module, Midia offers may applicatio otes which are istructios o how to wire i a wired module. Which kids of systems ca scramblers be used i? Midia has istalled voice scramblers i simplex radio systems, as well as repeater systems, trukig systems ad voted systems. Scramblers ca also be used with sigalig such as CTCSS, DCS, DTMF, 5-Toe ad MDC-1200. O the trasmit side the scrambler scrambles the audio prior to the sigalig beig ecoded ad o the receive side the scrambler descrambles the audio after the sigalig has bee decoded. Do the umber of security codes matter? Oly up to a poit. Midia s TVS-2 offers 4.29 billio userprogrammable codes plus 10,000 Midia cotrolled system ID s for a total of 42.9 trillio codes. Midia s VS-1200 offers approximately 4 billio user programmable codes from 6.2 x 10^23 total codes. To put this i perspective, it would take more tha 30 years to test oe billio codes at a rate of oe code per miute. Some maufacturers claim to offer more codes alludig to higher security, but that is just marketig hype. It is o more practical to try ad break a scrambler with a billio codes tha a scrambler with a trillio codes.

Hoppig Code Voice Scramblers TVS-2 Hoppig Code Scrambler Midia s TVS-2 offers a high-level of voice security for two-way radio commuicatios. By usig the hoppig code type of rollig code scramblig, Midia s TVS-2 offers a higher level of voice security versus other rollig code scramblers (see compariso below). The TVS-2 icorporates Midia s Kryptic sigalig format which allows for greater cotrol of fleet commuicatios (see below) ad the automatic detectio of scrambled/clear audio. A Dual Mode optio is available upo request for systems that require both rollig code ad voice iversio scramblig for iteroperability. The TVS-2 series has the followig features: Number of possible codes: ~ 40 Trillio Number of selectable keys: 4 5 user-programmable levels of voice security Level L4: 12-25 hops per secod Level L3: 6-12 hops per secod Level L2: 1.2-2.4 hops per secod Level L1: 0.8-1.2 hops per secod Voice Iversio Midia s Kryptic sigalig format for: ANI & Emergecy ANI Selective Callig Radio Kill Spy Radio Check Over-The-Air-Reprogrammig (OTAR) of the security keys Dimesios: 1.64 L x 0.84 W x 0.2 H Plug-i modules are available for HYT, Icom, Kewood, Motorola, Tait ad Vertex. Hoppig versus Sweepig Rollig Code Scramblers: Midia s TVS-2 uses the hoppig type of rollig code scramblig, istead of the sweepig type, for higher voice security. Both types of scramblers claim a certai umber of hops per secod. Sweepers (aka Hybrid Sweeper/Hopper) imply a higher level of voice security because they hop hudreds of times per secod. However, it is the legth of the hop that is importat rather tha the umber of hops per secod. Each hop of a sweeper is approximately 1 Hz i legth whereas each hop of a true hoppig scrambler is at least 300 Hz. Therefore it would take ~300 hops of a sweeper to equal the chage of a true hopper i oe hop. Because of the egligible frequecy chage of a sweeper, sweepers are susceptible to attack by trackig the sweepig with a phase lock loop (PLL) circuit.
