13、 ETSI ETSI TR 187 010 V2.1.1 (2008-07) 6 1 Scope The present document summarizes the work that is ongoing in relation to management of trusted identifiers (often referred to as the generic term Identity Management (IdM) within a number of international standardization bodies and industry fora. From

14、this summary, it identifies common themes which are relevant to IdM within ETSIs NGN activities and then presents the results of an IdM Threat Vulnerability and Risk Analysis (TVRA) based upon the method described in TS 102 165-1 i.1. The present document derives and presents a set of objectives and

15、 requirements for providing security of Identity and IdM in the NGN. NOTE: The issues raised in the present document have been analysed with respect to the NGN but apply equally to existing and alternative telecommunications networks. 2 References References are either specific (identified by date o
