Abstract: Provided are an apparatus and a method for anonymity-based authentication and key agreement which are capable of providing transmission message binding properties, which ensure that the messages received via a plurality of rounds by participants who desire key agreement as well as anonymity have been sent by the same counterpart participants. The provided apparatus comprises: a signature verification unit which receives a plurality of messages, each carrying a signature generated based on link information of a sender, and verifies the signature of each of the messages; and a binding checking unit which determines whether the messages have been sent by an identical sender, if it is determined by the signature verification unit that the signature is valid, based on the link information of the signature.

Abstract: PURPOSE: A method for managing a window to prevent congestion and a recording medium are provided to drive a timer, according as traffic is not generated in a persistent TCP(Transport Control Protocol) connection. CONSTITUTION: A method for managing a window to prevent congestion in a communication network providing an internet connection through an ATM(Asynchronous Transfer Mode) communication network, comprises the steps of: performing a slow start process when a connection state is in a traffic transmission state, by searching the connection state, and performing a control process of window size accordingly to packet loss; diminishing the window size accordingly as persistent time of an idle state reaches predetermined time, when the connection state is in a traffic transmission idle state, by searching the connection state; performing the slow start when a searched connection state of a transport protocol is in the traffic transmission state, by searching the connection state of the transport protocol; deciding whether transmitted packet loss exists, by searching whether the transmitted packet loss exists by the transport protocol connection; linearly increasing a congestion window value when the transmitted packet loss does not exist, performing a fast re-transmission process when the packet loss exists, and performing a fast recovery process.
