In order to protect the security of online transactions, e-commerce systems generally use PKI technology to meet the security demands of identity authentication, confidentiality and integrity of transaction information. But as storage carriers of digital certificate, IE browser is not safe or portable, and although USB-Key is relatively safe and convenient, it is easily be forgotten to carry. What's more, specific USB-Key can only be used for specific e-commerce service. In this paper, a mobile identity authentication scheme for e-commerce based on Java-SIM card is proposed which covers these shortages, and the Java-SIM Card security system is analyzed.
