| abstract |
The invention concerns a device for managing instances of a computer application (AP) accessing service providers (S1, S2, S3) assembled in groups (G1, G2), said groups being predefined to assemble the service providers which require execution of at least one operation of the application. It uses a common instance to access providers (S1, S2) of a common group (G1) so that said operation is executed only once for all the providers (S1, S2). The invention is useful for authenticating a user with service providers (S1, S2) having established a trust relationship with a common identity provider (I1). |
