Mostly we use password for Remote Authentication but Smart Card- based scheme is very promising and practical solution to remote authentication. Over the past several years, Smart Cards have achieved a growing acceptance as a powerful tool for Security, Identification and Authorization. Smart Cards have been widely used as simple token hardware in authentication process. As the e-business is growing rapidly via the internet, many organizations are implementing all the infrastructures that allow them to have secure e-business transactions. In this paper we study what is e-business, threats for e-business, security requirements for e-business and various authentication approaches for e-commerce transactions that allow partners to realize secure transactions.
