PD705 - DP4400 Encryption Compatability

[Sputnik1]

Hello all

another long shot but........

I have inherited a job where the previous radio company has put BASIC encryption into a fleet of DP4400 radios.

I have managed to figure out the 3 digit code and can now program successfully any other additional DP radio needed for their fleet

However.......

what I really really wanna do is:

to migrate some PD7 radios into the fleet but I need to know is if there is a way / formula / table which will give a compatible encryption code
for the PD7 fleet to communicate correctly to the Motorolas

Encrypt for DP radios allows 1 - 255 as a code in the BASIC encryption section
Encrypt for PD radios allows 1 - 255 in the ' Key ID ' box but allows adjustment of the ' Key Value '

unless I am missing something the Motorola 1-255 basic code is NOT the same as the Hytera 1-255 Key ID

am i p*****ing in the wind or is there a way to work a code to match the DP4400s ?????

any advice would be very welcome

thanks in advance

I don't know about the basic encryption, as I have never used it. I have also never used a PD705 or a DP4400. ha ha!

However! I have successfully used 10-Character Encryption on a PD782G with Enhanced Encryption on a XPR7550e. They are both 40-bit and both compatible.

Basic privacy is proprietary to Motorola. I haven't seen any other radios be compatible with it. As mentioned though enhanced privacy/ARC4 is compatible with other vendors.

In my experience, Moto’s enhanced encryption is equal to Hytera’s basic encryption. At least that’s how I got my XPR6550 to talk to my PD782.

there is differences between Motorola and Hytera Basic Privacy
Motorola Basic privacy is fixed keys mapped to (1...255)
Hytera Basic Privacy is more complicated and using 10ch 32ch and 64ch and 1 to 255 key mapped to this values
user can define those keys (10ch, 32ch, 64ch)
then user can not communicate between Motorola and Hytera radio in BP
but in EP, both using RC4 algo then they can talk with together.
