JSON Based Decentralized SSO Security Architecture in E-Commerce

SSO (single sign on) provides e-commerce users with easy access to applications and network resources, using a single, secure login identity. Web services (WS) based on SSO provide the potential to achieve interoperability of distributed electronic commerce (e-commerce) application integration among autonomous organizations, regardless of platforms, operating systems or languages. The most important challenge about the WS based on security SSO is the cost of implementation. After reviewing the paradigm of developing WS security standards and challenges, this paper presented a security model of JSON (JavaScript object notation) based on SSO architecture for e-commerce enterprise. The decentralized SSO security architecture is presented which is easy to integrate legacy system and new developed system.
