Dissertação (Mestrado em Engenharia) - Universidade Federal do Maranhão, São Luís, 2013.http://tedebc.ufma.br:8080/jspui/handle/tede/513The world today is moving the use of traditional systems to a computer model to offer its resources very dynamic and remotely, which is known as cloud computing. In compensation challenges arise related to security issue, which makes it clear that innovations require resources. Being an environment where there is sharing of computing resources by several organizations, it is necessary to define access to data and services, so that you keep the privacy of user identification of the environment. The first security mechanism on any computer system is the identity management through authentication. A user who has registered their identifiable information in a system will have guaranteed access to the system, if your authentication is proven. The objective of this work is to propose a model where the authentication given identity can be moved from one cloud to another to allow a registered user to access a domain to another domain. This authentication is performed through single sign that is sent encrypted via script.application/pdfAcesso AbertoComputação em nuvemGerenciamento de identidadeAutenticaçãoCloud ComputingIdentity ManagementAuthenticationCNPQ::CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAODissertação
