Abstract:
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. © 2022 Editorial Board of Journal on Communications.
