    Abstract: An image forming apparatus supporting peer to peer (P2P) connection includes a print engine to perform a print operation; a first wireless interface to connect the image forming apparatus to an access point (AP) of an infrastructured network; a second wireless interface to connect the image forming apparatus to an external mobile device by P2P; a soft AP module to allow the image forming apparatus to perform as an AP when the image forming apparatus is P2P connected; a dynamic host configuration protocol (DHCP) server unit to allocate an internet protocol (IP) address to the mobile device that is P2P connected to the image forming apparatus; a soft AP activating unit to activate the soft AP module; and a control unit. If a discovery packet is received from the mobile device via P2P interface, the control unit is operable to control the image forming apparatus to process the discovery packet.

    IPC: H04L9/08

    Abstract: A user key management method for a broadcast encryption includes assigning node path identifiers (IDs) to nodes arranged in sequence; assigning random seed value keys to the nodes according to the node path IDs; generating key values by repeatedly applying a hash function to the assigned random seed value keys; and assigning the generated key values to the nodes in sequence. Accordingly, it is possible to reduce the transmission overhead that is most important matter in the broadcast encryption to less than the number of the revoked users. Further, there is an advantage that the transmission overhead of the exemplary embodiments of the present invention is remarkably reduced compared with the Subset Difference method.

    Abstract translation: 用于广播加密的用户密钥管理方法包括将节点路径标识符（ID）分配给依次排列的节点; 根据节点路径ID向节点分配随机种子值密钥; 通过重复地将哈希函数应用于所分配的随机种子值键来产生密钥值; 并将生成的密钥值依次分配给节点。 因此，可以将在广播加密中最重要的传输开销降低到小于被撤销用户的数量。 此外，与子集差分法相比，本发明的示例性实施例的传输开销显着降低是有利的。
