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 ink-jet printhead and a manufacturing method thereof include a substrate on which a space portion is formed, a passage plate installed on the substrate in which an ink chamber is formed to store ink, a nozzle plate installed at a top surface of the passage plate in which a nozzle is formed to eject the ink, and a vibration plate disposed between the substrate and the passage plate to generate a pressure for ejecting the ink by changing a volume of the ink chamber. The vibration plate includes a base layer formed at a top surface of the substrate so as to cover at least a part of the space portion, a thin film shape memory alloy layer which contacts the ink contained in the ink chamber and varies according to a temperature variation, a heating element disposed between the base layer and the thin film shape memory alloy to generate heat, and an insulating layer disposed between the heating element and the thin film shape memory alloy layer and transfers the heat generated by the heating element to the thin film shape memory alloy layer. Due to a stable temperature coefficient of resistance (TCR) of the heating element, a height and a width of a voltage supplied to the heat element can be easily controlled, and thus power of the vibration plate can be precisely controlled, thereby having a predetermined image quality, and the heating element does not contact directly the ink, thereby realizing stability of the ink-jet printhead.
