Abstract
AbstractIn recent past SMS (Short Message Service) has become very popular data bearer in GSM networks. SMS, inherently being a messaging protocol, has always been point-to-point and in plaintext. For m-commerce transactions, SMS will be routed through public networks and some application servers of the merchant. Also, to protect itself against unknown roaming environments, SMS needs peer-to-peer object level security at the application level. This demands SMS to offer trustworthy model. The paper uses a novel philosophy to establish trust between users and services. We presented a model of trust and application level public key encryption of SMS with client authentication using JavaCard technology over GSM 03.48.KeywordsMobile UserShort Message ServiceCertification AuthorityMobile TerminateElementary FileThese keywords were added by machine and not by the authors.
