Abstract: The invention relates to a method of sharing a strong secret F between two parties (A, B) previously sharing a weak secret F, this method of sharing combining a symmetric algorithm and an asymmetric algorithm, and consisting in using a fixed exponent e of small size, and in encrypting not the exponent e, but the modulus n, by means of the weak secret f.

Abstract: The invention relates to a system, enabling subscribers of a wireless Telecom Operator to execute financial transactions with a mobile phone, or an electronic device which can be connected to the wireless communication network, wherein a subscriber has one or several Financial Transaction Accounts open and managed by the Telecom Operator, which can receive monetary deposits, and on which debit and credit operations can be executed. The system is composed of a Transaction Processing Platform, which is installed on the computers of the Telecom Operator, is connected to the wireless communication network, is interfaced with other elements of the Telecom Operator, manages the Financial Transactions Accounts, verifies/executes financial transactions sent by the subscribers, and executes other tasks like confirmations of transactions, account statement preparation, reporting, etc.

Abstract: A request for approval is sent to a payee, in a Simple Payment scenario, to accept or reject a transaction. A subscriber to the Financial Transaction Service has the ability to set up Special Lists of Financial Transaction Accounts which are submitted to Particular Rules to be applied when such accounts are involved in transactions with the subscriber's own account. Such particular rules are checked and implemented by a Transaction Processing Platform and/or by a mobile handset and/or the SIM of the subscriber. The Special Lists are stored in part or integrally in files connected to the Transaction Processing Platform and/or in memory of the mobile handset and or in a memory of the SIM. The Financial Transaction Account number of a subscriber can be read automatically by another subscriber. The validation of a Payment Request that is sent to a Payer for approval is facilitated by the display on his mobile handset of the Payee's name or logo or an easily recognizable sign or an audible message.
