UBITECH is proud to announce a major milestone in the company’s strategic positioning in trusted computing and standardization: on September 3, 2025, the IETF working group published a new Internet-Draft, “Direct Anonymous Attestation for the Remote Attestation Procedures Architecture” (draft-ietf-rats-daa-08), which adopts UBITECH’s efficient DAA approach for privacy-preserving platform authentication and attestation. UBITECH’s Dr. Thanassis Giannetsos, Head of Secure Systems & Trusted Computing (SST), serves as co-editor of the draft, formally establishing UBITECH’s leadership in modern attestation standards. By integrating UBITECH’s DAA modular implementation, architected by Mr. Stefanos Vasileiadis (Tech Leader, Trusted Computing at UBITECH’s SST Research Group), agnostic to the underlying HW-based Root-of-Trust, into the overall RATS architecture, the IETF draft provides evidence of UBITECH’s strategic position and leadership of in the attestation standardization community. This marks a significant reinforcement of UBITECH’s positioning at the intersection of trusted computing, privacy-enhancing technologies, and open standardization.
Key Highlights & Strategic Significance
The publication of the new IETF draft represents a major validation of UBITECH’s pioneering role in trusted computing and privacy-preserving attestation. The document formally incorporates UBITECH’s Direct Anonymous Attestation (DAA) scheme into the IETF Remote Attestation Procedures Architecture (RATS), providing an authoritative standardization reference for the company’s innovation.
As co-editor of the draft, Dr. Thanassis Giannetsos, together with Mr. Stefanos Vasileiadis, played a central role in shaping how DAA integrates into the RATS ecosystem, guiding the development of privacy-aware attestation methods that balance verifiable trust with anonymity. The draft acknowledges UBITECH’s TPM Direct Anonymous Attestation (DAA) Library as the open-source implementation of the proposed mechanisms, recognized as production-grade and distributed under an MIT license—underscoring UBITECH’s commitment to open, interoperable security foundations.
The adoption of DAA into the RATS architecture establishes a clear pathway for enabling anonymous attestation in remote verification processes. This innovation allows devices and systems to prove their integrity without revealing their unique identity, a crucial capability for privacy-sensitive environments such as the Internet of Things, edge computing, and multi-tenant cloud infrastructures.
Beyond the technical achievement, the draft highlights UBITECH’s growing influence within international standardization efforts. By contributing a privacy-preserving trust mechanism directly into an IETF architecture, UBITECH has reinforced its position as a driving force in shaping the future of secure and trusted computing. This milestone affirms the company’s role not merely as a contributor but as a leader defining the next generation of open standards for attestation and verifiable trust.
“This adoption by IETF is validation of our long-term vision of privacy-preserving trusted computing. It signals that UBITECH is not just participating in the standardization of attestation but is shaping it,” said Dr. Thanassis Giannetsos. “We remain committed to delivering practical, open, high-assurance implementations aligned with global standards, and this marks a turning point in how anonymity and trust can coexist in remote attestation systems.”
UBITECH’s prior work in trusted computing, hardware roots-of-trust, secure enclaves, and open cryptographic primitives has built to this moment. This announcement further strengthens UBITECH’s brand as a leading contributor in the intersection of cybersecurity, privacy, and standardization.
