Integrated Encryption in Dynamic Arithmetic Compression
A compression cryptosystem based on adaptive arithmetic coding is proposed, in which the updates of the frequency tables for the underlying alphabet are done selectively, according to some secret key K. We give empirical evidence that the compression performance is not hurt, and discuss also aspects of the system being used as an encryption method.
