Latest Patents

Nam-su Jho holds a patent for a "Method of managing user key for broadcast encryption." This innovative method 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. 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 effectively 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 significantly reduced compared to the Subset Difference method.
