File compression and encryption based on LLS and arithmetic coding
e propose a file compression model based on arithmetic coding.Firstly,the original symbols,to be encoded,are input to the encoder one by one,we produce a set of chaotic sequences by using the Logistic and sine chaos system(LLS),and the values of this chaotic sequences are randomly modified the Upper and lower limits of current symbols probability.In order to achieve the purpose of encryption,we modify the upper and lower limits of all character probabilities when encoding each symbols.Experimental results show that the proposed model can achieve the purpose of data encryption while achieving almost the same compression efficiency as the arithmetic coding.
