MARQUES, Fábio; DIAS, Gonçalo Paiva  and  ZUQUETE, André. Modelo de segurança para a composição dinâmica de workflows em arquiteturas de e-government. RISTI [online]. 2012, n.9, pp.15-26. ISSN 1646-9895.  https://doi.org/10.4304/risti.9.15-26.

Interoperability architectures allow the creation of transversal workflows in the public administration and the integration of services from the perspective of citizens and businesses. In this paper we present a security model to address the security issues that are raised by an interoperability architecture that supports the dynamic composition of e-government workflows by autonomous agents. The model is based in a Public Key Infrastructure and a set of data structures which are supported on well-known standards (X.509 V3 and WSDL). It addresses agent identification, authentication, accreditation and authorization and ensures that results produced by agents are privately delivered to their intended recipients even though those recipients may not be known when the results are produced.

Keywords : e-government; Security; Dynamic workflows; Privacy; Interoperability.
