Leveraging the HyperLedger blockchain platform and drawing upon lessons learned from digital rights management (DRM) initiatives, NIRA is working with the Defense Technical Information Center (DTIC) to develop a solution that promotes effective document and data publication and sharing within the defense research, development, test, and evaluation (RDT&E) community. In addition to high availability and confidentiality, the LEDGEr-based Network for Document Distribution (LEDGENDD) enables easy document authentication and integrity verification, traceable document delivery, and fine-grained access control beyond initial dissemination. We will discuss the unique challenge of integrating the HyperLedger blockchain platform with the DTIC semantic web technology foundation while ensuring transaction privacy and deterring transaction-pattern-based, side-channel attacks. With a consensus mechanism designed for mixed trust environments, the LEDGENDD architecture aligns with the RDT&E community governance structure.
