We propose an approach using elliptic curve-based
zero-knowledge proofs in e-commerce applications.
We demonstrate that using elliptic curved-based zero-
knowledge proofs provide privacy and more security
than other existing techniques. The improvement of
security is due to the complexity of solving the discrete
logarithm problem over elliptic curves.
Index terms E-commerce, security, privacy, zero-
knowledge proofs, elliptic curves.
E-commerce is not dead, but it is thriving! According
to the eSpending report, online shoppers spent $2.95
billion during the second week of December 2003,
