| Summary: | To solve the problem that the existing electronic ticket systems are challenging to deploy in resource-constrained devices and cannot prevent the sharing of tickets among unauthorized devices, a privacy-preserving attribute ticket scheme based on mobile terminal with a smart card was proposed.The smart card was a secure and constrained-yet-trusted core device that holds secret information and performs lightweight operations.The mobile terminal was a powerful helper device that handles key-independent and time-consuming operations.Firstly, the efficient attribute-based ticket scheme deployed on the mobile terminal with a smart card was constructed by combining a pseudorandom function, anonymous ephemeral identities scheme, aggregatable signatures with randomizable tags, and Pointcheval-Sanders signatures.Secondly, the security model of the electronic tickets system was presented, and the proposed scheme was proved to be unlinkable and unforgeable.Finally, the proposed scheme was implemented on a personal computer, a smart card (Aisinochip ACH512), and a smart phone (Huawei Honor 9i), and the comparison and experimental results show that it is efficient. |
