Abstract
Disclosed herein is a data encryption technique that pertains to a data stream that divides into data samples. Each sample is truncated by a predetermined number of bits to make room in the data stream for an encryption data packet. The truncation reduces the resolution of the data in exchange for security features. The encryption data packet includes a counter to prevent replay attacks and an HMAC to verify contents and synchronize the frames of the data stream. The data is encrypted and transmitted to a receiver where the data is played.
