Smart water resource is the advanced stage of the development of water resources informatization. The following construction conceptions of it can meet the development requirements of water resources informatization under the new situation well, such as resource sharing, business collaboration, intelligent applications, etc. The emergence of Internet of Things, Big Data and Cloud Computing has profoundly changed the technical environment of water resources informatization, and brings new challenges in security assurance. On the basis of analysing the current situation and existing problems of water resource informatization and its security assurance system construction, the conception of smart water resource is defined exactly, the overall architecture design scheme of smart water resource is proposed, the main security threats to smart water resource are analyzed in detail, the security architecture of smart water resource is put forward, and also the key technologies of security assurance under the new situation are discussed.
