MATLAB: Chaotic bit stream cipher

Question

Hello

I have a sets of data stream, i want to encrypt the data streams using chaotic system or logistcs map. unfortunately the codes i have found are used to encrypt images, could i use the same code for the data streams?

thanks in advence

Answer 1

Logicists maps can be used for this purposes, as they only need to know the current state.

"cat map" on the other hand requires 2D arrays. In theory you could create a 2D array of encryption information, and then keep a 2d state variable that reflected your current virtual position in the array, moving between the positions according to cat map.

But what you are asking is algorithm questions, and you should be researching in algorithm sources.

It is not entirely clear whether we are legally permitted to assist you with code for this purpose; the USA has strict laws about code for encryption purposes, and I think it likely that further discussion of implementing MATLAB code would pass those legal limits.
