 06 Feb 2005 6:05 Dongle Protection |
|
|
|
I've recently heard about dongles also known as Hardware locks... i got interested in them but i was unable to find any info... Can someone help me regarding the following:
1. What actually is a dongle?
2. Some pictures of a dongle
3. What is the mechanism involved along with its internal structure.
4. Is it possible to beat the dongle protection.
5. Why a printer port and not any other is chosen for the dongle.
Please Help...

| I don't have a photograph of a dongle but from what I have already seen it had a small pcb with a microcontroller with erased numbers connected to assorted lines + 3-state RS-232 driver and DB-9 male and DB-9 female at both ends..

| When a software is started it checks for the presence of a dongle on a port (parallel, serial, etc) by sending certain string of data which dongle reads and sends back to PC its string which the software accepts (can be more than one exchange) and continous its operation..

What do you meam the dongle reads a string? In what way? Whether a gate has a 0 or 1 and then it interprets the data and then send it back to the PC...
Now, is it not possible for me to replicate the same signals, the dongle sends to a pc using another chip? If yes, then even this protection is not completely foolproof...so, did they come up with any upgraded models, or do you have any idea about the current trends?

That is why dongle is not popular any more.
As far as current trends, I think it is on-line registration with codes to activate software sent directly to you..

Oh...Dongles are not popular anymore? Thanks for that...i never knew that...i was still thinking that dongles are used even today... As far as online registrations are concerned...i think they are good but definitely the best...

And by the way, i still didn't get my answer for this:
What do you mean when you say that the dongle reads the data sent?
Please clarify
