DESCRIPTION

The basic idea was simple, the signal is received, passed through the codec, converted to hex values, then passed through my algorithm where it is scrambled, passed to the output buffers and back out through the codec

• The purpose of this project is basically to implement a strong audio encryption algorithm that has not been covered in the labs

• The basic idea was simple, the signal is received, passed through the codec, converted to hex values, then passed through my algorithm where it is scrambled, passed to the output buffers and back out through the codec

The encryption process

I also monitored the graphs of the signals I was working with

• This next slide shows the input and output before encryption, as it should be

These next two slides show the graphs before and after encryption respectively

The graphs confirm that the signal was scrambled adequately and the project was a success.
