Embodiment Construction

[0044] exist figure 1 Here, reference numeral 1 designates a communication terminal configured to exchange data with a computerized server 4 via a telecommunications network 3 . Communication terminals 1 include, but are not limited to, stationary personal computers (PCs), mobile laptop computers, mobile wireless telephones and / or mobile personal digital assistants (PDAs). Each communication terminal 1 has a display 11 and data input means 12, such as a keyboard and a pointing device (eg computer mouse, trackball, etc.). The communication terminal 1 comprises a client application, preferably a browser (such as Microsoft Internet Explorer or Mozilla Firefox), in order to access a server 4 residing on a server 4 via a telecommunications network 3 through a secure session established with a secure session establishment protocol such as SSL / TLS. online application. In addition, the communication terminal 1 includes an authentication module 2, which will be referred to later fi...

Abstract

For authenticating a user using a communication terminal (1 ) to access a server (4) via a telecommunications network, a personal identification code is received from the user. From secure session establishment protocol messages exchanged (S1 , S2, S3) between the communication terminal (1) and the server (4), a data set is generated (S4). Based on the data set, a transaction authentication number is generated (S52) using the personal identification code. The transaction authentication number is transmitted (S54) from the communication terminal (1 ) to the server (4). In the server (4), the transaction authentication number received is verified (S20) based on the secure session establishment protocol messages exchanged with the communication terminal (1). The transaction authentication number enables session aware user authentication that protects online users against real-time man-in-the-middle attacks.

Description

technical field [0001] The present invention relates to a method and a device for authenticating a user accessing a server. In particular, the invention relates to a method, a computer program product, and a method for authenticating a user accessing a server through a telecommunications network using a communication terminal, and accessing a computerized server. Background technique [0002] Tampering attacks on login mechanisms are growing rapidly on the Internet. Institutions such as banks have introduced two-factor authentication devices, some even including high-speed and even higher-cost challenge-response mechanisms. Man-in-the-middle (MITM) attacks pose a serious threat to all online applications based on SSL / TLS, such as Internet banking. (TLS) protocol standard (Dieks, T. and C. Allen, "The TLS Protocol Version 1.0", Request for Comments 2246, January 1999) requires the use of mutual authentication based client certificates. However, outside the tight grip of co...
