I think that is on the low side, too. Just for starters.

Do you have access to lasers and stuff like that ? What about photon polarity and the Heisenberg uncertainty principle ? what about Bob and Alice ?
From what I understand, it's a lot more than just source code; and probably what is available right now must be under lock and key in the hands of a few companies and research departments around the world.

Ordinary lasers won't due. You need ones that are capable of emitting a single photon at a controlled polarization. The actual algorithm used isn't complex and could be simulated easily enough but would not be secure since the inability to be eavesdropped on is fundamental to the quantum nature of the data transfer.

Agreed and those kind of lasers are probably not sold at Circuit City.

Probably not at Fry's Electronics, either :->

Alright, I've got to google that.

Just hope they are on good terms with each other. Now, nobody point lasers at anybody's eyes

Well technically thats still encryption then.

i think it can be done virtually in a computer.. i googled my doubts and i got good results.. it is said that it can be done virtually without the use of photons.. we need to encrypt the messages with different qubits.. which is defined by the representation of the bits which need to be sent.. all we have to do is to make an hidden channel.. but i got no clue how to do that????
can any1 who understood the above concept explain me???
Help of any kind r welcome....
Thank u,

You need a computer that stores information as qubits, not mere bits, otherwise it's not quantum at all. AND, there are only two implementations, and they both use photons - one uses polarization, the other entanglement. It's not just a software thing - not just any computer can do it.
You obviously have no idea about this, and quantum computing isn't for the faint-hearted, or the clueless. And anyway, QKD is tied-in with encryption, so basically it's not what you're looking for at all.

Well, you've just communicated something without encryption. What else you want to demonstrate ?

Are you trying to track a package sent via IPS? Isn't that the fictitious company that Doug Heffernan works for?

If anybody knows about that simulation program, Please help me to find AES simulation program.
Thank you.

The only AES I know about is an encryption scheme, also refered to as Rijndael encryption method. Are you looking for information about this algorithm, or are you asking for something else?

Thanks for your answering Skippums
The AES is common knowing algorithm nowadays. I'm looking for the simulation program for the AES only. The simulation program which is a real AES program that shows some operations' results inside AES on the screen. First, I need to compare between encryption time of the AES for certian data and encryption time for my algorithm for same certian data with AES aslo. Second, I need to check the randomness of the key generator. Third the check the....., Fourth......
Therefore i'm looking for the simulation AES program.
Maybe anybody knows about that, please help?
you can get idea about simulation program from here.

You are important person.
Thank you.

Sorry, but I don't know anything about an AES simulation program... I have used the .Net class in C# before to perform encryption, but that is about the extent of my knowlege. Sorry I can't be more help.
