| Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 85 === The purpose of this thesis is to study entity authentication
schemes of smart cards and to compare the efficiency between
them. The author has classified the schemes into three
categories-schemes using symmetric cryptographic keys, or using
asymmetric keys, and those based upon the zero knowledge theory-
and pointed out which is better in terms of efficiency.
Secondarily, the author has included electronic commerce as an
application field, and studied the feasibility of utilizing the
cards in proposed systems, such as SET, as a payment instrument.
Smart cards will replace magnetic cards in the future, because
of their strength in security, portability, and expandability.
