Apparatus and method for authenticating user for network access in communication system

Abstract

An apparatus for authenticating a user for network access in a communication system comprises: an input module contained in a subscriber terminal for receiving and transferring identification information and a password for network access from a user; an authentication supplicant contained in network equipment for requesting network access authentication for the identification information and password transferred from the input module; an authentication server for storing information related to the network access authentication, and for performing authentication to determine whether to permit the subscriber terminal to access a network in response to the authentication request; and a protocol authenticator for performing protocol processing between the authentication supplicant and the authentication server. A corresponding method is disclosed. Thus, it is possible to authenticate subscriber terminals for network access without the installation, by an Internet service provider, of specific software (e.g., a supplicant program) in all of the subscriber terminals.

Description

technical field [0001] The present invention relates to a communication system and, more particularly, to an apparatus and method for authenticating a user for network access in a communication system. Background technique [0002] As network services using communication systems are diversified, limited services are often provided to users according to network service types. [0003] In a limited service, a network service provider using a communication system performs an authentication process in which it is confirmed whether a user or device wishing to use a network service is authorized to use the service before the service starts. For example, if a device or user not authorized for a particular network attempts to access a local area network (LAN) to request a particular network service, the service provider blocks the unauthorized device or user through an authentication process to prevent it from using the particular network service. [0004] In order to perform such ...

[0012] This places a burden on Internet Service Providers (ISPs) wishing to provide security without setting specific requirements or restrictions on subscriber terminals

That is, because an ISP must install specific software (such as a requester program) in all subscriber terminals in order to provide secure network services, it is necessary to consider initial costs and additional software management costs for subscriber terminals in providing related network services, so given ISP adds heavy lifting
