Benefits of technology
The solution enables secure, unified access to multiple services by automating the authentication process, reducing the need for multiple login credentials and access cards, thereby enhancing user convenience and security while minimizing piracy risks.
Problems solved by technology
These ways of doing do not allow meeting the initial security goals sought by such authentication which can then be compromised.
However, such a system provides access to one service only.
Moreover, card readers cannot be shared with the access cards of other service providers.
This way is on the one hand not convenient for the user and on the other hand not rational from both an economical and ecological point of view.

Embodiment Construction
[0040]Referring to FIG. 1, the latter shows an overview of the system relating to the method of the present invention. This method aims a mutual authentication between a user 1 and a service provider 20 among a plurality of service providers. The user is registered to each of these service providers, e.g. by means of a user account. Only three providers are represented in the example of FIG. 1 but it should be understood that more providers will be generally involved. According to the invention, this mutual authentication is carried out by means of an authentication device 10 shown in the figures in the form of a smart card. In order to authenticate both the user 1 and the service provider 20 with whom the user wants to have an access, data 30 has to be exchanged between these two entities. According to one embodiment, such a data exchange is performed via a terminal 40, typically a personal computer within a home environment 45. To this end, the terminal 40 is firstly provided with...

A method for authenticating a user to a provider, among a plurality of providers. The method uses an authentication device comprising, for each of provider, a record comprising a pairing key and first data, both as shared data. Provider authentication data comprises a first cryptogram obtained by encrypting said first data with said pairing key. Authenticating provider authentication data is performed at the authentication device by the steps of decrypting said first cryptogram by means of the pairing key stored in one of said records, then comparing the result of this decryption with first data resulting from pairing data stored in said record, if the comparison does not indicate a match, then processing again the previous decryption and comparison steps by using the pairing key of another record until each of said records stored in the authentication device has been processed.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 133,219 filed Dec. 18, 2013, which claims priority to U.S. Provisional patent Application No. 61 / 740,459 filed Dec. 21, 2012, and European patent Application No. EP 12198886.9 filed Dec. 21, 2012. All of the forgoing are incorporated by referenced herein in their entireties.TECHNICAL FIELD[0002]The present invention relates to the field of electronic data exchanges, such as on-line services or e-commerce, requiring a mutual authentication between a user and a service provider, among a plurality of providers to which this user has an account. Such authentication is required each time the user wants to access to the service of the provider. In particular, the invention provides a solution for securely managing access to a plurality of services (each of them being provided by a specific service provider) by means of one authentication device which avoids the user to re...
