    摘要: A method of allowing a packet in a network image forming apparatus includes setting user account information corresponding to the plurality of network interfaces, determining allowability of a received packet by using information included in the received packet and the set user account information, and when the received packet is allowable, performing an operation corresponding to the received packet. Accordingly, in an image forming apparatus installing a plurality of network interfaces, not only allowability of each interface to each user but also a type of protocol provided to each user can be setup. Consequently, an environment that can use an interface in various forms according to each user can be provided.

    摘要: A combination-based broadcast encryption method includes: assigning by a server a base group of different combinations to each user; producing and sending secret information for each user by using as a base the base group allocated to each user; producing and sending an inverse-base parameter value through calculations with integers used to produce the base group and key value information of one or more privileged users; and deriving a group key by using the key value information of the privileged users, encrypting a session key by using the derived group key, and sending the encrypted session key to each user. Accordingly, each user is assigned a different base through a combination, thereby having security against collusion attacks.

    摘要: An apparatus and method for generating a key for a broadcast encryption. The apparatus includes a node secret generator for managing a user that receives broadcast data in a tree structure and for generating a unique node secret for each node in the tree structure. The apparatus also includes an instant key generator for temporarily generating an instant key used at all nodes in common in the tree structure, and a node key generator for generating a node key for each node by operating the node secret generated at the node secret generator and the instant key generated at the instant key generator. Thus, key update can be efficiently achieved.
