A simple protocol for digital cash by elliptic curves
Shuo Shen, Samuel S. Wagstaff · Annual Information Security Symposium · 2004
Digital cash is an important application of modern cryptology. Traditional cash spreads germs, and people can steal it from the owner. Checks and credit card have an audit trail; you can't hide to whom you gave money. Digital cash can avoid all these defects. There have been a lot of excellent protocols designed for digital cash, which allow for secure and untraceable transactions. In this poster, we try to create a simple and efficient protocol of digital cash by use the powerful mathematics theory of elliptic curve.
