Abstract :
A new secure digital communication scheme is presented which is based on hyperchaotic synchronisation. The message is masked and easily recovered. The chaotic masking signal shows strong randomness. The length of the secure key is calculated to be >200 bit. The security of speech communication is significantly increased
