Quotes

Isolated Cloud IDMS Isolated Cloud Identity management system is based on the common deployment model used by the small or medium organizations. In an isolated Cloud IDMS, single server acts as a Service Provider (SP) as well as the Identity Provider (IdP) and is responsible for the storage of identity information and user operations (Alrodhan and Mitchell 2010; Cao and Yang 2010; Jøsang et al. 2005). A common use case is depicted in Figure 3, prior to the service acquisition, (1.1) CSCs are required to perform authentication at the CSP. Here, CSP redirects the user’s authentication request to its own IdP for further processing. After successful authentication, (1.2) an authentication response is generated and returned to the corresponding user. This identity management system does not rely on a Trusted Third Party (TTP) for the credential issuance and verification. However, Isolated IDMS becomes unmanageable with the increase in services and resources, since each service needs to know the credentials of authorized users (Cao and Yang 2010; Jøsang et al. 2005).
