Title: Hyunsoo Choe: Inventor of a Scalable TLS Access-Control Mechanism

Introduction

Hyunsoo Choe is an inventor based in Kirkland, Washington, and is associated with Amazon Technologies, Inc. His work includes a patented approach to enforcing client-certificate access control for internet services using Transport Layer Security (TLS).

Latest Patents

Choe is credited with 1 patent: “Mechanism for Enforcing Access Control at Scale to an Internet Service Using Transport Layer Security (TLS).” The invention describes systems and methods for a scalable load balancer to support client-certificate access control through mutual TLS authentication.

The system receives trust-store files containing a certificate authority (CA) bundle and a certificate revocation list (CRL), then combines them into a single trust-store file. It distributes snapshots of that file to load-balancer nodes, which use the snapshots to verify client certificates against trusted CAs and check whether a certificate appears on the CRL. If the certificate is trusted and has not been revoked, the system forwards connection data to an application target.

Career Highlights

Choe’s patent focuses on making certificate-based access control practical at scale. By consolidating trust information and distributing snapshots across load-balancer nodes, the described method supports certificate verification and revocation checks as part of the connection process.

Collaborations

The supplied information lists Sathyaprasad Srivatsa Ramaseshan and Dhruva Gaidhani as Choe’s coworkers. Their shared professional context is associated with Amazon Technologies, Inc.

Conclusion

Hyunsoo Choe’s patented work addresses scalable TLS-based access control by combining certificate validation, revocation checking, and connection routing in a load-balancer system.
