Sir,
I tip my hat to you. Well done!

by **GEMOTO** » Wed Mar 15, 2006 3:31 pm

Very nice and well written. I learned a lot from that article.

by **RKG** » Thu Mar 16, 2006 2:50 pm

I concur.

exceptional article. thanks

Looks good.

Just a quick observation (havent finished the whole article yet)

I must disagree with you about the security of DVP-XL being better than DES-XL.

The keylength is longer, but the algo strength is.. Questionable.

Result: DVP-XL is most likely less secure than DES-XL, due to a most probably weaker encryption algo than DES-XL.

Still, its great to finally see some effort going into collecting together all the moto secure stuff.

Cheers,

Pete

Good stuff.

RSA didn't develop PGP, though. PGP was developed by Phil Zimmerman, who was persecuted for doing so in a fairly well publicised three year long court case several years ago.

Also, the length of a keyspace alone does not indicate that one cipher is stronger than another. Compare elliptic curve to traditional finite field or integer factorisation cryptography, for example - you'd need 15,000-bit RSA keys to achieve the same level of security as you'd see in 512-bit ECC.

Where did you find this? It looked to me the opposite was stated (des more secure than dvp)

by **ogoun** » Sat Mar 18, 2006 5:02 am

About half way down the fourth page, where it states: "DVP-XL is MORE SECURE than DES-XL".

Overall, I am impressed with this PDF. It is LONG overdue. I hope to be able to contribute to it soon. Hopefully it will become a "living document", with revisions and additions being made as they are discovered.

Cheers

All I have to say is "Wow".

I finally understand how encryption works on Motorolas now.

Shame I can't play with it where I usually use my radios.

Thanks, Batdude.

Is there any way we can get a copy of this either on the discussion board or on the Batlabs site? My company's firewall and access policy prevent me from accessing aol.members.net or other "standard" discussion boards...

Thanks.

I'll mirror it for Batdude for the people that cannot access AOL servers.

I'll repeat the kudos of everyone else so far on an excellent article, and add my 2 cents by stating how pleased I am that we now have what was sorely missing in lots of previous works: Pictures of the actual items!!!

Keep the stuff coming!!

Jaymz--

Thanks for the accessible posting.

Batdude--

It is an excellent article.

I'm anxiously awaiting the remaining sections.

Are there any photos we can contribute?

Between us all, we possess at least one of everything /\/\ ever built.

I'm running a couple Spectra's and X9000's with DVP....old skool baby! Need pics?

by **Jim2121** » Sat Aug 26, 2006 5:48 pm

very nice work Batdude......

by **proff** » Thu Nov 09, 2006 9:09 pm

YOU LEGEND
BUT IN AUSTRALIA
motorola online "not advalable".
can any one else get these boards and if yes , where did you get them?

by **mr.syntrx** » Thu Nov 09, 2006 10:49 pm

From private sellers in the USA.

Unless you can find an ex police DVP SYNTRX or something, that is.

by **proff** » Sat Nov 11, 2006 12:42 am

the company I work for has over 30
XTS3000 radios , so thats why I need at least 15 encryption boards.
If there is this amount of pcb's some where for sale please let me know.

And here some pictures of the old stuff - the inside view of a NTN5763C-module :-)

Really amazing how much electronics they stuffed into those tiny modules...

Fell free to use the photos for whatever you want.
