Latest Patents

One of Myung-hwan Kim's latest patents is a method of managing user keys for broadcast encryption. This method involves assigning node path identifiers (IDs) to nodes arranged in sequence. It also includes assigning random seed value keys to the nodes according to the node path IDs. Key values are generated by repeatedly applying a hash function to the assigned random seed value keys. The generated key values are then assigned 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 is remarkably reduced compared to the Subset Difference method.
