摘要

Anonymity protecting mechanisms are an important part of any Trusted Computing platform. They provide protection of a plat-form's anonymity and, consequently, protection of the privacy of the platform's owners. As Trusted Computing technologies have been intro-duced on mobile and embedded systems and more and more mobile de-vices are equipped with Near Field Communication (NFC) modules, the question arises whether the supported anonymization mechanisms can be used efficiently for anonymous authentication for NFC enabled ap-plications. However, state-of-the-art technologies like the Direct Anony-mous Attestation scheme require complex mathematical computations that put high requirements on the processing power of the signer's de-vice which are typically not available on resource constrained devices like smart-cards. In this paper, we analyze how the Direct Anonymous Attestation protocol can be used for anonymous authentication in NFC scenarios and we propose an approach that allows a practical use of this technology in real-world scenarios.
