Title: Eun-Sun Yoo: Innovator in Broadcast Encryption

Introduction

Eun-Sun Yoo is a notable inventor based in South Korea, recognized for her contributions to the field of broadcast encryption. She has developed innovative methods that enhance user key management, which is crucial for secure communications.

Latest Patents

Eun-Sun Yoo holds a patent titled "Method Of Managing User Key For Broadcast Encryption." This patent outlines a user key management method that includes assigning node path identifiers (IDs) to nodes arranged in sequence. It also involves assigning random seed value keys to the nodes according to the node path IDs. The method generates key values by repeatedly applying a hash function to the assigned random seed value keys and assigns the generated key values to the nodes in sequence. This approach significantly reduces the transmission overhead, which is a critical aspect of broadcast encryption, to less than the number of revoked users. Furthermore, the transmission overhead of this method is remarkably reduced compared to the Subset Difference method.
