_PUFrt receives OCP S.A.F.E. Scope 3 approval following an independent security 
assessment of its resistance to physical attacks that could compromise sensitive
information stored in silicon._

SAN JOSE, Calif., Oct. 19, 2026 /PRNewswire/ — PUFsecurity, a subsidiary of eMemory
Technology, **was spotlighted at Microsoft’s Caliptra Workshop** on October 12, 
the opening day of the sold-out 2026 OCP Global Summit. The workshop drew nearly
400 attendees.

In his talk, "Caliptra Specification to Silicon Reality & a Turnkey Solution for
Ecosystem Integrations," PUFsecurity Principal Security Architect Kent Chuang highlighted
how PUFrt helps bring the open-source Caliptra specification into production-ready
silicon for AI data centers.

**PUFrt has also received OCP S.A.F.E. approval following an independent Scope 3
security assessment and is now listed on the OCP Marketplace**, marking an important
milestone in advancing hardware security for cloud and AI infrastructure.

**PUFrt: The Physical Security Anchor for the Caliptra Architecture**

Caliptra is an open-source hardware Root-of-Trust architecture developed under the
Open Compute Project (OCP), designed to provide every chip in cloud servers with
a verifiable identity and a trusted boot path.

As AI infrastructure continues to expand rapidly, **every chip within a data center
must have a verifiable identity**. **Caliptra is becoming the standard for establishing
this trust**, while PUFrt provides the underlying physical security foundation, 
from key generation to chip mass-production testing, ensuring security throughout
the supply chain and enabling large-scale deployment across the ecosystem.

PUFrt integrates eMemory’s NeoPUF technology to generate chip-specific Unique Device
Secrets (UDS), NeoFuse anti-fuse One-Time Programmable (OTP) memory for on-chip 
data storage, and an entropy source compliant with NIST SP 800-90B standards. As
an early adopter of Caliptra, PUFrt **has already been successfully integrated into
Caliptra products from ASPEED, a leading provider of server management chips (BMC/
SMC)**, as well as security systems from several major memory manufacturers and 
networking-related chips.

**OCP S.A.F.E. Scope 3 Approval: Independently Assessed for Physical Attack Resistance**

PUFrt completed its Scope 3 assessment in 2026, focusing on **its ability to resist
physical threats, including fault injection and side-channel attacks**. The OCP 
S.A.F.E. program provides an industry-wide, standardized, and independent security
review framework for hardware and software, helping customers avoid repetitive security
assessments.

For silicon Roots of Trust, resistance to physical attacks is particularly important
because the cryptographic keys and device secrets they protect serve as the foundation
for higher-level security functions.

**Supporting the Agentic AI Era with Caliptra**

As AI infrastructure evolves to support Agentic AI workloads capable of autonomous
decision-making, data center security architectures are rapidly transitioning from
proprietary, closed systems toward standardized, open-source architectures such 
as Caliptra.

**PUFrt now fully supports Caliptra 1.x and 2.x silicon IP requirements on advanced
process nodes**. Through PUFsecurity’s "**One-Stop-Shop Service**," chip design 
teams can access a complete, pre-validated solution integrating Caliptra and PUFrt,
covering verification, certification support, and end-to-end engineering guidance,
significantly shortening the development-to-mass-production timeline.

The OCP Marketplace listing for PUFsecurity’s OCP S.A.F.E.-approved PUFrt is available
[here](https://www.opencompute.org/marketplace/security-systems-management/pufrt/).

**About PUFsecurity**
