A fluid conduit connector assembly includes a connector having a body with an inner surface defining a fluid channel. The sheets of paper P on the standby tray are dropped, fed, and moved to the processing tray, thus the conveying path from the standby tray to the processing tray is shortened. Accordingly, a size of an operation result si of the binary operation is set to be constant at bits, and, as a result, an input size of an RSA signature generation function is set to be constant.
