adams-bridge

About this tag
The tag adams-bridge refers to a component of Microsoft's Azure security architecture, specifically an open silicon root of trust (Caliptra 2.0) that includes an integrated post-quantum cryptography accelerator. Based on recent discussions, Adams Bridge is part of Microsoft's Secure Future Initiative, which aims to harden Azure from silicon to systems. It works alongside the Azure Integrated HSM, Azure Boost DPU, and other hardware security measures to provide per-server cryptographic isolation and supply-chain transparency. The tag also appears in the context of Microsoft's quantum-safe roadmap, where Adams Bridge supports post-quantum cryptography readiness across Azure infrastructure.

    Azure Integrated HSM: Per-Server On-Chip Crypto for Secure Cloud

    Microsoft has quietly moved one of the most sensitive elements of cloud security — the Hardware Security Module — from dedicated cluster appliances into the silicon and chassis of individual Azure servers, embedding a custom Azure Integrated HSM ASIC across new fleet servers as part of a broader...

    Azure Per-Server HSM and Open RoT with PQC Accelerators

    Microsoft’s cloud team has quietly re-architected the silicon under Azure to treat nearly every element of a server as a discrete security boundary — and it's shipping that architecture at scale across new servers this year and into 2025. What started as a collection of academic and hyperscaler...

    Azure Silicon-to-Systems Security: Hardware Roots, Attestation, and Supply-Chain Transparency

    Microsoft’s latest push to “harden Azure from silicon to systems” stitches together a clear thesis: security must be built into every layer of the cloud stack — starting in silicon and extending through firmware, host controllers, attestation, and immutable supply-chain evidence. The company’s...

    Microsoft's Quantum Safe Program: From PQC Testing to Enterprise Migration by 2033

    Microsoft’s public roadmap for a quantum‑safe future is no longer a research manifesto: it’s a multi‑year engineering and procurement plan that maps how SymCrypt, Windows, Azure, Microsoft 365 and silicon will evolve to resist the cryptanalytic power of future quantum computers. The company has...

    Microsoft's Quantum-Safe Roadmap: PQC Rollout Across Windows and Hardware

    Microsoft’s public roadmap for a quantum-safe future marks a decisive shift: the company is moving from research experiments to a staged, product-level rollout of post-quantum cryptography (PQC) across its cryptographic libraries, identity systems, and hardware roots of trust — and it’s asking...
