Numerous organizations have pressed in the past several years for improved security and privacy in online interactions. Stakeholders have encouraged the adoption of privacy-enhancing technologies, utilization of microcontrollers and hardware devices for key storage and attestation, and improvements to the methods and policies used for authentication. Cryptographers and security engineers have responded to these calls. There have been numerous papers published in the last decade on topics such as private information retrieval and anonymous authentication and the Trusted Computing Group (TCG) has released a version 2.0 standard for Trusted Platform Modules (TPM). Adoption and implementation of these techniques, however, has been lacking. Although the TPM 2.0 specification was released in 2014 there are no reference implementations of direct anonymous attestation algorithms compatible with the hardware. The purpose of this work is to implement and discuss the implementation of direct anonymous attestation on TPM 2.0 and to consider the scalability and performance of direct anonymous attestation schemes operating on real-world TPM devices.
