What is it about?
The speech signal is compressed and encrypted in a single step, from point of view of security this system has strength encryption, and faces all the attacks to break the security. In other hand, the reconstructed speech quality is very good.

Why is it important?
This system can compress and encrypt the speech signal in one step with sampling rate lower than shanon rate. This should be reduced the time consuming and memory required.
