The fast development of web services, or more broadly, service-oriented architectures (SOAs), has prompted more organizations to move contents and applications out to the Web. Softwares on the web allow one to enjoy a variety of services, for example translating texts into other languages and converting a document from one format to another. In this paper, we address the problem of maintaining data integrity and confidentiality in web content delivery when dynamic content modifications are needed. We propose a flexible and scalable model for secure content delivery based on the use of roles and role certificates to manage web intermediaries. The proxies coordinate themselves in order to process and deliver contents, and the integrity of the delivered content is enforced using a decentralized strategy. To achieve this, we utilize a distributed role lookup table and a role-number based routing mechanism. We give an efficient secure protocol, iDeliver, for content processing and delivery, and also describe a method for securely updating role lookup tables. Our solution also applies to the security problem in web-based workflows, for example maintaining the data integrity in automated trading, contract authorization, and supply chain management in large organizations.
