Embodiment Construction

[0044] figure 2 The mobile telephone 1 shown can be used to implement the method of the invention. The mobile phone 1 conventionally comprises a microprocessor (μP) 15 linked via a data, address and control bus 16 with transmit / receive lines (ER) 17 , program memory 18 , and a data memory 19 . The bus 16 is also connected to an interface 20 (actually a connection means) which establishes a connection via a connection means 21 to a smart card 2, in particular a SIM type card. In the same way, the chip of the smart card 2 includes a microprocessor (μP) 22 connected to a program memory 24 and a data memory 25 via a bus 23 of the same type as the bus 16 . Microprocessor 22 is capable of executing a subroutine 26 stored in program memory 24, referred to herein as SIM. The SIM subroutine is a typical program, especially during the first connection of a mobile phone 1 to the mobile phone network 3, to request the entry of a Personal Identification Number (PIN) to use the mobile ph...

Abstract

The problem of real-time neutralising or revoking of a X509-type certificate, belatedly available in a public database (BD) is solved by directly neutralising (35) in a mobile telephone (1) a sub-programme (26) of signature and / or transmission of certificates concerning transactions to be validated. Thus by doing so neutralisation is achieved in the ten minutes following the signalling, or the neutralisation request, whereas it requires 24 to 48 hours in normal administrative circuits (AE, PB).

Description

technical field [0001] The present invention aims to provide a transaction authentication method and device. The present invention is designed mainly for various mobile phones (GSM, GPRS, UMTS, etc.) to manage transactions between mobile phone users and trading partners. Background technique [0002] Well known transactions are those involving buying and selling. However, the transmission of information to a trading partner and the entrusting of the trading partner with the task of ascertaining the authenticity of the information transmitted to him can also be regarded as a transaction. It is also conceivable to apply the invention within the framework of access control; in this case, transactions are generated by an access permission request. For simplicity, the invention will be described in the context of a sales operation, since a sales operation is truly representative of the various problems that may arise during such transactions. However, the present invention inv...
