Bronze Member Username: DesiplanetzPost Number: 49 Registered: Mar-09 |  To help you all understand In response to the number Of Threads/Post being made Through Out the DSS/FTA Community i have Put together this Thread To help you Understand What N3 is And what You can Expect .. About Nagra 3 Q. What is Nagra 3? A. Nagra 3, also referred to as N3 & Nag3 is the newest encryption system being implemented on DN & B3V. Q. Why is Nagra 3 causing us problems? A. Because all FTA use on DN & B3V uses an older system, Nagra 2. The coders know Nagra 2 like the back of their hand. Nagra 3 is new and needs to be mastered & broken. DN & B3V are switching things over to Nagra 3. Q. What is the cardswap? A. The cardswap is the effort by B3V & DN to switch out the access cards used by subscriber boxes. The cards they are replacing are nagra 2 cards and are being replaced with new Nagra3 cards, also referred to as the ROM240 (B3V), ROM241 (DN). The new DN cards are sometimes referred to as "G3" cards since G3 is on the front of them. Q. FTA doesn't use cards, why is this affecting us? A. Because the software used in your FTA box is likely modeled on the older card that uses Nagra 2. The coders have yet to break and understand how the new card using Nagra 3 works. Therefore they cannot write software (the BIN file) to work with Nagra 3 yet. Q. How long until everything goes Nagra 3? A. Exact dates are unknown. B3V completed its cardswap awhile back and is testing N3 only channels. Expect it to go completely dark aound the 1st of November if not before. DN has recently started its cardswap and will take significantly longer to complete. DN HD channels could go dark as soon as November sometime as indications are that they are swapping HD customers with N3 cards first. Q. Will Nagra 3 be hacked? A. Nothing can be promised but all past and current indicators are that yes, a hack of some sort will eventually surface. Do not expect to see or hear of it until the DN cardswap is complete. It also may or may not require you to use a Nagra 3 card in your FTA. This early on in the game it is educated guesses and speculation. Q. Some of my B3V channels are missing, or I just have audio. What is wrong? A. Odds are that those channels are using Nagra 3. Audio on many channels is not encrypted or is still using Nagra 2, that would be why you may have sound on HD channels but no picture. At this point there is nothing that can be done to get it back Q. will i have to buy another receiver? No you will not - just wait till after N3 and all info needed will be Posted How does it work I have seen a bunch of talk about Nagra 3 being implemented and tested in the data stream so I figured I would explain a bit about how encryption works so that folks understand a bit more about why these rumors are false and why they shouldn't worry about the release of Nagra 3 so much..... Just so you know, this is a simplified version... professional encryption is a huge deal with several formulas, algorithms etc..... but just as encryption is huge so is DECRYPTION...... in other words, for every person making encryption there is 5 working to decrypt it.... All of them working for our stb manufacturers..... Here is a basic idea of how encryption works : All encryption is based on a mathematical formula.... For example... you start off with a code to crack and the idea is that you want to find out how many apples Johnny has in his bucket..... here is how the systems would work... NAGRA 1..... this works on basic addition (not really.. this is the part where I am makin' it simpler).... You start off with someone leaking that there was originally 3 apples in Johnny's bucket.... The only mathematical process Nagra 1 knows is addition..... so... the provider sends down the number 5 in the data stream... through basic addition your formula tells you to add 5 apples to the original 3... you get eight and boom..... you know the answer.... A simple calculation like this would be done millions and millions of times by your receiver in seconds..... this produces your tv pic using binary language.... When the provider uses addition to change the amount of apples originally in the basket you need a new bin file to help your receiver decrypt the signal.... NAGRA 2...... Now you introduce subtraction into the mix... now the provider can change the number of apples originally in the basket both ways... add more or take some away..... the equation is twice as complicated and your receiver has to work double time...... every once in a while the equation gives you a previous number used because due to subtraction you can go back to a previous number.... This is what happens that causes a previous bin file to work..... NAGRA 3... Ok... let's say this bad boy can do multiplication..... now your equations are 3 times as difficult... it is harder for coders to find the formula.... Your number of original apples can now go from 100000 to 2 in a flash of a second due to multiplication...... your receiver is working triple time...... it takes the coders longer to learn how many apples are in the basket...... Bottom line... the bad news is that you may not have any apples in your basket for a while since the coders will need time to figure this out....... The good news is that they are geniuses and a whole lot of rich folks will be losing a pile of money until they get some apples back in your basket......LOL..... no worries..... we will get some downtime but we will be back up and running.... |

Silver Member Username: JoeturnPost Number: 188 Registered: Apr-06 | I for one understood it to its fullest. Can you cypher this out and put it in laymans terms just for me?#months and counting<;-) http://www.scribd.com/doc/9350917/The-NagraVision3-Hacking |

Platinum Member Username: NydasPost Number: 14844 Registered: Jun-06 | joeturn : It is a detailed analysis of what they believe to be the Nagra 3 software. I have downloaded the pdf file and am trying to understand it. IF I can, I will post, otherwise DesiPlanetz or somebody more knowledgeable than me may do so. |

Silver Member Username: JoeturnPost Number: 189 Registered: Apr-06 | Dont loose it Nalin you might be interested in related articles and the index at the bottom of the page! Ps I would not worry about the smart coming to explain its existance! I just keep thinking UNK has directed me to it. Its been there 3 months with outbeing posted |

Silver Member Username: UbbaPost Number: 193 Registered: Sep-06 | My question is any idea when the DN channels that are not HD might become completely black? Thanks so much. |

Silver Member Username: JoeturnPost Number: 204 Registered: Apr-06 | That will never happen before 2012! SD might become obsolete but the Federal Government wont allow SD programming to cease in existance! There would be pandamonium in WASINGTON DC.The majority of TV sets are still SD. |

This so called NEW technology of DIGITAL was improved by narrowing its band width from 12.5 mhz to 6.125 mhz 40 years ago. Going back in time is a stupid idea! Even the terminology is worked up wrong SD means Standard Definition meaning low pixelization,HD means High Definition 1080ppi and greater! They are calling SD= anolog and HD= digital(c4FM) "Oh what a tangled webb we weave" |

Silver Member Username: JoeturnPost Number: 207 Registered: Apr-06 | "If we practice to decieve" The second paragraph in the broadcastnow link is decieving! How can doubling its bandwidth be saving bandwidth? I'de say its more like job security for the next wave of NEW technology of putting things back the way they are now! Uncle Ruport saw this coming miles ago when he realized new technology THE INTERNET was killing his newspaper bidniz! So his NEW goal is to have an INTERNET monopoly$$$$$$$$$$$$$$$$$$$$ |

Silver Member Username: JoeturnPost Number: 227 Registered: Apr-06 | After a closer analysis I have came to the conclusion that the internet has destroied the economy! Not only the paper bidniz but internet shoping has created a loss of jobs world wide,gamblers stay at home and use cheatware putting the casinos in jeoperdy. The casinos inturn create online sites that does away with dealers,bit bosses ect...Disney has went down 50% as people can see it all for free on the internet! Likewise hollywood is about to go under as the big studios cant compete with pirates that use the internet for their cheatware.Free tv has put a damper on the satellite providers. This modern technology is soo convenient it is staving us all to death with price hikes.Most every job lost can be directly linked to the World Wide Webb's influience$$$$$$$$$$$$$ and the beat goes on |
