Abstract
The ability to securely transmit information between two locations is of paramount importance in today's communication systems. Before the invention of digital transmission methods, analog transmission was commonplace. However, today's communication systems rely almost exclusively on transmitting information digitally. Digital transmission has become commonplace because it provides optimal accuracy and security. However, digital transmission also has drawbacks, for example, increased bandwidth requirements and the loss of information when converting information between the analog and digital domains. The present invention relates to a method and apparatus for encrypting analog data while minimizing data loss and conserving bandwidth.
