Abstract

With the exponentially growing number of users, who are accessing online services, easy authentication became a key factor. A trusted and secure platform can enable seamless authentication in most of the applications. This paper extends the possible use of the Subscriber Identity Module (SIM) as authenticator in the online world. The paper proposes Near Field Communication (NFC) technology as a transfer technology between the mobile handset and other devices. A possible architecture is shown, future SIM requirements and secure key transfer are addressed. Scenarios for different security or user needs are shown and appropriate key policies are suggested. Solutions are focused on ease of use, security and the needs of different usage areas.
