Abstract :
In this work, an attempt has been made to design and synthesize speech encoding and encryption as a system-on-chip. The novelty of this design is that it uses wavelet decomposition for data compression and perpetual audio masking to keep quantization noise level to a minimum. The encryption is done by implementing an RSA algorithm in hardware.
