Abstract

This Prior Art Search Report presents the results of a comprehensive search conducted in support of a provisional patent application filed with the United States Patent and Trademark Office (USPTO) for the invention titled "Systems and Methods for Device Security Attestation Architecture (DSAA)." The DSAA invention comprises five integrated subsystems — Dual-SIM Mutual Attestation (DSMA), Differential Network Analysis (DNA), Multi-Sensor Environmental Attestation (MSEA), Hardware-Rooted Trust Chain (HRTC), and Autonomous Downgrade Resistance System (ADRS) — collectively forming a unified on-device architecture for cellular network security.

The search encompassed all available records through April 2026 across the following databases: USPTO Patent Full-Text and Image Database (PatFT), USPTO Patent Application Full-Text (AppFT), Google Patents, the European Patent Office Espacenet database, WIPO PCT International Patent Database, IEEE Xplore Digital Library, ACM Digital Library, arXiv preprint repository, and Google Scholar. Classification codes searched included H04W 12/12, H04W 12/126, H04W 12/06, H04L 9/32, G01S 5/02, and H04W 48/16. Search queries were organized by subsystem and encompassed approximately 80 distinct search term combinations.

A total of 30 prior art references were identified and analyzed across eight categories: SIM Swap Prevention Patents & Standards, Cell-Site Simulator / IMSI Catcher Detection, Multi-SIM Security Research, Device Integrity and Attestation, Sensor-Based Security and Location Verification, Network Downgrade Attack Prevention, Relevant Standards and Frameworks, and pSIM/eSIM Conversion and Management
