This population of stable connectivity is also causing some serious matters on user information security. Thus, on designing career-class subscriber networks, concerns should be made not only on system scalability, but also security between each subscriber. In this paper, we first compare various traditional methods for subscriber aggregation, and show that each method has weakness either in security or scalability. Thus, we propose a new method for subscriber aggregation, based on RFC3069, which satisfies both security and scalability issues.}, pages = {281--286}, publisher = {情報処理学会}, title = {IPネットワークにおけるセキュアかつスケーラブルなユー ザ収容方式の検討}, volume = {2002}, year = {2002} }
