00:00:03

will try to program the

00:00:07

Kalta DMR radio station, the Kalta radio station

00:00:10

in our case, the pH 660 model

00:00:15

in this line there is also a 600 model

00:00:18

without a display with the same dimensions and a 690 model

00:00:21

with a full-size keyboard about

00:00:24

programming to work in a closed

00:00:26

channel using encryption

00:00:29

method A from a key length of

00:00:32

256 bits and we will combine it today

00:00:36

with Motorola, first we will program

00:00:39

the card then we will program Motorola

00:00:41

we will enable encryption And if 256 and check

00:00:45

whether these models are compatible Is

00:00:47

this encryption compatible Will everything work for us

00:00:50

the station is now factory reset

00:00:52

to the factory settings to zero, so I read it,

00:00:58

we won’t do all the settings carefully, you

00:01:01

and I will only focus on the

00:01:03

basic ones that we need to work in the

00:01:06

basic settings, we’ll check if there are

00:01:10

any specific options that

00:01:11

could interfere with us, the language here is not

00:01:15

important to us Now you don’t have to select it,

00:01:19

we move immediately through the menu items in the

00:01:23

direction of the

00:01:25

list

00:01:27

secret keys encryption keys you can

00:01:31

activate any key length you and I

00:01:35

will be interested in the key Let me remind you that

00:01:38

for the rc4 encryption method it does not

00:01:41

matter In what order the

00:01:43

keys are in the list for the

00:01:46

iOS encryption method does not important From what length of the

00:01:50

key 40 bits 128 256 is important not

00:01:54

only the content of the key, not only its

00:01:56

length but also its place in the list of keys, this is

00:02:01

important, always remember this If you have

00:02:03

Key number one at one station and the

00:02:06

same key at the second station at

00:02:08

number 2, encryption already works according to the

00:02:11

method And if it doesn’t So we add,

00:02:14

we can, of course, add more keys here,

00:02:17

but we don’t seem to need it now We are

00:02:20

now interested in one key, so we

00:02:22

will have k1 We will call it that, and from the

00:02:28

length y we will be 64 64 multiplied by 4 and it

00:02:34

just turns out 256 so this

00:02:37

method

00:02:39

indicates the key length 64 characters in the

00:02:43

S method it will be 256 characters 256

00:02:47

key length but here it is not

00:02:50

displayed we are interested

00:02:52

in having

00:02:53

some kind of key generated for us so

00:02:55

we add a

00:02:57

new key from number 3, for example,

00:03:01

64 characters. Here we have generated it and then we will

00:03:07

use the

00:03:09

third key. Although, by and large,

00:03:14

Yes, she swears at us about the designation of the

00:03:17

key. And there are 3, let it be so.

00:03:21

We immediately copy this value to ourselves in a

00:03:26

text editor

00:03:28

so that we registered the value in

00:03:31

Motorola, how long is it here? 64

00:03:33

characters this will be our

00:03:35

256-bit key for iOS encryption in the

00:03:39

table we entered the key Okay now

00:03:43

Let's move on Demerkin crowned Basic

00:03:46

settings

00:03:47

check here the

00:03:49

radio station identifier here

00:03:51

we leave all the parameters at default

00:03:54

this is already a taste and the color of who is

00:03:58

programming what, we check if there are

00:04:00

any parameters that could

00:04:02

interfere with us again, everything is fine here. We

00:04:05

go to the incript section,

00:04:08

we check the incript Mode, that is, the encryption mode is

00:04:13

soft ingript Well, in the demo you are different and do not

00:04:16

select

00:04:19

Voice Only Data Only in this radio station Voice and Data,

00:04:23

select Voice Only Because if you

00:04:26

select Voice and Data, then

00:04:29

not only the contents of your packets will be encrypted,

00:04:31

but also the

00:04:35

Destination and fields, that is, Where does

00:04:38

the signal come from ID person Where

00:04:42

does the call come from and, accordingly, its

00:04:45

direction if group current groups ID

00:04:48

if individual call then

00:04:51

the individual number of the called

00:04:53

correspondent, this data will also be

00:04:55

encrypted, and if on the other

00:04:57

side it is

00:04:59

only troop encryption that is activated,

00:05:02

then no routing will be

00:05:04

carried out, it will be especially important to

00:05:05

remember this. When you work through a

00:05:08

repeater that sees you transparently

00:05:10

with a bridge, that is, it lets everything through

00:05:13

and It will also allow encrypted traffic

00:05:15

if the encryption is

00:05:17

only Voice Only because it needs to

00:05:20

understand where the signal is coming from and where.

00:05:22

Therefore, in typical cases, in most cases

00:05:25

we select Voice Only in the Motorola, it

00:05:29

will be easier for you there in old firmware this

00:05:32

option is not available at all in new firmware.

00:05:35

just let’s see

00:05:36

here everything is clear, we don’t touch the call System

00:05:40

and we got to the Digital Channel,

00:05:43

select the channel settings, let’s

00:05:49

take the frequency for testing,

00:05:55

let it be 446 050, let’s call it like this Color

00:06:00

code 1 time Slot one, let it be

00:06:03

written directly cleanliness

00:06:09

here, unfortunately not like a motorized car Or

00:06:12

how to trick with the ability to copy from the

00:06:16

receiving unit to the transmitting frequency RX

00:06:19

grouplist Compose by default If

00:06:21

you need some other one, you choose

00:06:24

your other one that is relevant for your

00:06:27

network

00:06:29

And here is the important point: choose

00:06:32

nq encryption If you leave

00:06:36

Basic here, then that one will be used the same

00:06:40

set of encryption keys that we entered in the

00:06:42

table, but the encryption method will be

00:06:44

proprietary from calcium. I don’t know which one.

00:06:48

If you select in Hands advanced,

00:06:51

then here below when choosing a key you

00:06:56

will already see If you had a

00:07:00

ten-digit key specified in the table and you select

00:07:03

it from this list, encryption will be

00:07:05

carried out using the arc4 method

00:07:09

using a 40-bit key 10 by 4

00:07:11

40 If you here select a key with a length of

00:07:15

32 characters or 64 characters from our

00:07:18

list, then it will be

00:07:21

128-bit encryption or

00:07:24

256-bit, respectively, we are with you under number a C3,

00:07:27

under this name,

00:07:29

we programmed a 64-character key

00:07:32

that corresponds to A, there are 256 bits, we

00:07:37

select it. We have selected

00:07:39

everything in this channel, our setup is

00:07:42

complete, we have a channel

00:07:46

called [music]

00:07:48

d446050, let’s remember this moment

00:07:51

Okay, here we don’t touch anything further.

00:07:54

We need to now a simple test, this is in

00:07:57

principle and there is no need to record

00:07:59

the radio station

00:08:04

while the station is being written, I

00:08:06

forgot to say TX Contact, our unit

00:08:10

is a group call number one and

00:08:14

RX grouplist, of course, also a

00:08:17

contact list with these contacts

00:08:20

number one, just in case, I’ll show you

00:08:22

so that it is clear the contact

00:08:26

group call identifier one and RX

00:08:30

grouplist actually He is in this

00:08:34

list we

00:08:36

have a kalta we programmed

00:08:40

actually on this channel we have it

00:08:43

now it remains to

00:08:44

program Motorola Motorola

00:08:48

as a sample Motorola we will

00:08:50

use Motorola SL

00:08:54

400010

00:08:56

functional it is identical to Motorola

00:09:01

models such as

00:09:05

dp44004600

00:09:07

48007 and

00:09:11

4401461 481 34 41 361 all basic

00:09:18

basic functions including

00:09:21

encryption encryption methods that

00:09:23

they can do and I have it at hand today

00:09:27

so we are working with it,

00:09:30

our code is open Motorola posters

00:09:34

first of all you need to make sure in

00:09:36

your Motorola whether your

00:09:38

NPP license is activated you have it here in the

00:09:42

configuration in the main settings, it

00:09:45

will be immediately visible if it is activated.

00:09:48

Here is the icon A from the line Well, and

00:09:53

it will be purchased or activated there

00:09:55

it says

00:09:56

if it is Yes, you can move on if

00:09:59

it is Well, then accordingly you need to take

00:10:02

care first of all about activation And

00:10:05

if only then we can continue without

00:10:07

this, nothing will happen, but we have it

00:10:09

activated. Let's go to the

00:10:12

settings in the general settings, let's check

00:10:16

some parameters

00:10:18

so that nothing interferes with us, but

00:10:22

theoretically there

00:10:24

shouldn't be anything that interferes with us, here all the

00:10:26

default parameters the station has been reset to

00:10:28

factory settings, look especially

00:10:32

especially nothing here from the parameters that

00:10:36

would affect our experiment right now,

00:10:38

we don’t seem to be here, so we don’t

00:10:42

touch it, we go to the defense

00:10:46

in the Motorola, it’s implemented a little differently,

00:10:48

everything is not like kalto type of

00:10:51

confidentiality here

00:10:54

Motorola asks you to decide what

00:10:57

we will do work with basic

00:10:59

confidentiality That is, this is even But

00:11:02

this is encryption in essence, but it is more

00:11:04

like an

00:11:06

inversion voice scrambler only

00:11:08

in digital mode, something like this,

00:11:11

if we choose basic, then we

00:11:14

will work with fixed keys, there are

00:11:20

255 of them in total fixed

00:11:24

keys We won’t work with them we are

00:11:27

interested in improved encryption that’s

00:11:30

when we chose improved we have here with

00:11:33

you next we need to enter the value of

00:11:36

the keys the

00:11:37

first table after the

00:11:41

privacy type we have

00:11:43

improved privacy keys This is

00:11:47

arc4 40 bits 10 characters come out

00:11:53

here one two three 4 5 6 7 8 9 0 10

00:11:59

characters won’t fit in there anymore This is

00:12:03

our arc4 40 bit we’ll call it RC

00:12:09

4

00:12:12

to use iOS 256 encryption we

00:12:17

go down to the value of the symmetric

00:12:21

key here where the symmetric key is

00:12:24

already here We are dealing with using the

00:12:27

NPP encryption method we add a key

00:12:31

estimate kay we will call it the same as we

00:12:34

called it on the map

00:12:37

remember that in the table since in tracing paper

00:12:40

we made three keys the table we

00:12:42

should also have three keys

00:12:45

does not matter any set of characters

00:12:47

we do for one key

00:12:54

we add a second one we add 3 here we

00:13:00

can also have any value

00:13:03

as much as we want and

00:13:06

we also call the third key on the list A

00:13:10

from 3 just like we did in the map and

00:13:14

here we insert from our

00:13:16

text notebook the value of this

00:13:19

key that we used in the tracing paper

00:13:23

we insert is

00:13:26

Key number 3 This is also an important

00:13:29

point, always remember that the

00:13:33

key must be in the same position

00:13:36

as at other stations. Okay, there is a

00:13:39

symmetrical key, then

00:13:42

check the parameters below, because if you don’t

00:13:44

enter an arbitrary key somewhere, even

00:13:47

any system will not write the code for the plug

00:13:49

radio station in ours In this case, this always

00:13:52

happens with just a key,

00:13:54

we register any arbitrary one just so

00:13:56

that the parameters are recorded because well,

00:13:59

we won’t use it anyway, right

00:14:00

now we register an arbitrary one,

00:14:03

then we don’t touch anything and

00:14:06

go

00:14:08

to contacts, remember that we had a

00:14:12

clever contact number one

00:14:15

identifier One he had check here the

00:14:18

same group call

00:14:20

identifier number one

00:14:23

look at the lists of reception groups

00:14:29

sheet one number one added excellent by

00:14:34

default the parameters matched We do

00:14:37

n’t need to do anything else here go

00:14:39

directly to the channel itself

00:14:43

Zone 1

00:14:49

opens for a long time and take channel number

00:14:52

one

00:14:53

edit it

00:15:01

let’s call it 446

00:15:06

050 so that it looks like

00:15:10

Color code 1 time Slot one so that everything is the

00:15:14

same as in Kalta OK we

00:15:19

leave these parameters at default do not

00:15:22

touch

00:15:23

here where confidentiality is

00:15:27

not checked if we check this box

00:15:30

then rc4 40-bit encryption will be used in this channel

00:15:32

which

00:15:36

we will select from the first list,

00:15:38

uncheck the

00:15:41

symmetrical alias or in English,

00:15:46

this is ours is 256 and here

00:15:51

from the list We select Key number 3, I

00:15:53

repeat, it can be

00:15:56

number 123 10 it doesn’t matter, the main thing is that

00:16:00

this number is identical in your

00:16:03

stations

00:16:04

you chose a symmetric alias and And there is

00:16:08

number three, excellent

00:16:09

decryption of a fixed secret

00:16:11

key, we check the box here now, for the sake of

00:16:14

experiment, we don’t set to ignore

00:16:16

unprotected voice packets when

00:16:19

receiving data, we also don’t set If you check it,

00:16:22

then you will only hear

00:16:24

your encrypted signal, you won’t hear other signals

00:16:26

you will,

00:16:28

but Kay, we don’t need it here

00:16:33

because we have the Access Security tutor in a

00:16:35

direct channel with you now, we wo

00:16:37

n’t use it any

00:16:40

further, we move

00:16:45

all these default parameters, we don’t touch anything

00:16:51

and we get to prescribing purity 4460, a

00:16:58

convenient moment You can copy the parameters

00:17:03

As you can see below Here we have a list of

00:17:06

receiving groups RX sheet 1 where we have a contact with

00:17:09

ID 1 and for transmission there is also a

00:17:12

group call contact with

00:17:15

ID 1

00:17:17

time-out timer we don’t touch the free

00:17:20

channel here we’ll put it like in tracing paper you can

00:17:23

always transmit so that

00:17:26

essentially everything is the same for ours experiment, we have

00:17:29

all programmed and are recording the

00:17:32

parameters of the radio station, an

00:17:37

important point is an important point when you

00:17:41

are

00:17:42

registering the keys.

00:17:46

Don’t forget

00:17:48

to watch. More precisely, not when you register

00:17:51

the key, when you select encryption in the channel,

00:17:55

remember that a symmetric key is just that,

00:17:58

but just

00:18:01

confidentiality is either basic

00:18:04

encryption or rc4 40 bits depending on

00:18:07

what we chose from the list so we

00:18:11

recorded

00:18:13

the station signed up and we are ready for the

00:18:18

final stage of our experiment so

00:18:21

now all that remains is to understand how to output both of them so

00:18:25

that it can be seen So 446 by 50

00:18:29

This is the only channel that we

00:18:31

programmed on the Motorola itself

00:18:34

we see the key is on, that is, encryption is

00:18:37

active, we check that we have the

00:18:43

same history on the card, the lock is on, encryption

00:18:47

is active, the channel is what we need 446

00:18:51

050, let's try to call Motorola 123 123,

00:19:00

this is what we are calling Motorola,

00:19:03

let go with

00:19:08

one hand, shoot with the other, say, please

00:19:10

forgive me Dear viewers, no it’s

00:19:14

very convenient to do all this in makeshift

00:19:16

conditions

00:19:18

and We pass on

00:19:20

123 123

00:19:23

here it is, our reception

00:19:27

has been released

As we can see

00:19:30

again here 1 2 3 1 2 3 1 2 3

00:19:40

I’m releasing

00:19:43

NPP encryption works without problems

00:19:47

between tracing paper and Motorola, the main thing is to

00:19:50

carefully take your time and set everything up correctly

00:19:52

and, moreover,

00:19:54

encryption using the ies algorithm will

00:19:58

work on any equipment where

00:20:01

this method is supported in the

00:20:04

etsi standards, including its

00:20:09

structure and those manufacturers that

00:20:11

support this algorithm are described Naturally,

00:20:14

it will work Regardless of

00:20:17

which manufacturer it is, it has

00:20:18

already been verified for those who have already since then, the

00:20:21

unbelieving Foma, the

00:20:25

compatibility of this encryption between

00:20:28

Motorola Calta Hitera Kenwood radios has been verified. I apologize,

00:20:37

DMR, some versions are something that has already

00:20:41

been tested, something that is functioning, I am

00:20:44

sure that there are still manufacturers

00:20:46

who also provide full

00:20:49

compatibility of NPP and arc4 encryption with

00:20:53

other manufacturers, that is, the

00:20:55

protocols are standardized, which means will

00:20:57

work on almost any hardware

00:21:00

by 99 percent Thank you for your attention

00:21:03

friends I hope this information was

00:21:05

useful to you
