摘要:A multi-service smart card system enables users to access di®erent services over an open network with a single smart card. Due to its highly economic and social bene¯ts, the multi-service smart card system has drawn much attention in industrial and academic areas. However, the big hindrance to its wide em- ployment is the risk of breaching users' privacy and their service con¯dentiality across di®erent service systems. This paper proposes a secure multi-service system model to overcome such problems. The model allows users to access di®erent services with a single password. The privacy and service con¯dentiality are achieved through a set of protections|password protection, user identity protection, and service trans- action protection|to guarantee the user's anonymity to all service systems and ensure high unlinkability between di®erent services.
