What are the objectives of National Service Delivery Gateway (NSDG)? Mention any eight (8).

The objectives of the National Service Delivery Gateway (NSDG) are as under: To act as a core infrastructure for achieving standards-based interoperability between various e- Government applications implemented at various levels and geographically dispersed locations. To evolve Gateway messaging standards and build a government owned Central Gateway based on these standards. Act as a catalyst in enabling the building of Standards based e-Governance applications with Gateway as the middleware to ensure interoperability. Enable integration across Centre, State or Local Governments thereby enabling Integrated Service Delivery and a Service Oriented Architecture (SOA) leading to joined up government. Help protect the legacy investments in software and hardware by easily integrating them with other technology platforms and software implementations De-link the back-end departments/Service Providers (SP) from the front-end Service Access Providers thereby Ensuring separation of concerns of service access from the service implementation i.e. separates the Portal, CSC, Kiosks etc from the government services which reside in the backend departments. Encouraging competition at the front-end by allowing independent service access providers to provide services with varying levels of complexity, cost and service quality levels. Enable adding of shared services on to the core services as and when required, as special common services of the Gateway without affecting the core functionality of the Gateway, thereby providing flexibility and modularity. encourage back-end services to be plugged into the infrastructure as and when they are ready, Reduce the cost of e-Governance Projects by rationalizing, distributing and optimizing the services framework. Use Public Key infrastructure for secure transactions. Provision exists for encryption of department payload to ensure confidentiality of department data. The gateway provides digital signature and certificates to all stakeholders interacting with the gateway for identification, authentication and authorization. Transaction and audit logs help track government data. Enable transaction logging and time stamping for tracking of transactions and centralised control. Help the Departments backend workflow evolve gradually as the Gateway acts as a middleware delinking the backends from the front end. This means that even the departments which do not have the complete automation or work flow at the back can still deliver e-Service to the citizens in a limited manner through the Gateway.
