Abstract:

Money is core part of human activities and paper cash has existed for very 
long time in history of civilized human. With advances of technology 
today, digitizing paper cash is a good attempt because it enhances payment 
systems into a great extent. However, turning a paper cash into a string 
of ones and zeros leads to critical issues of how to make it secure, how 
to protect payer's privacy, how to divide denomination, and how to 
transfer this piece of digital string to others. In this thesis, we study 
on digital cash in an approach of how proposed schemes solve these 
critical issues, and analyze the difficulties in designing, implementing 
and deploying digital cash systems.
