Abstract: The present invention relates to a roaming electronic transaction terminal. It also relates to a secure system for electronic transactions comprising one or more roaming terminals. The terminal (1) has an application package support (2) and a coupler (3) for carrying out the read and write operations on a medium that are required for the electronic transactions in conjunction with the application package. The coupler (3) comprises means for creating a write time window and a read time window on the basis of a secure input signal, all writing and all reading being disabled outside of the corresponding windows. The invention applies notably for the securing of terminals carrying out checks and contractual transactions on supports equipped with processors and memories, it being possible for these supports to be through contactless read and write cards comprising for example transport entitlements, payment means or any other entitlements to be turned to account.

Abstract: A method of modifying a set of secrets in a cryptographic module, to ensure that the modifying is either successful or invalid. The module includes readable version numbers for each secret and for the set of secrets. If the version number of the set of secrets is equal to a version number requiring the loading of a set of new secrets, the version number of the set of secrets of the cryptographic module is set to a distinctive number indicating that the cryptographic module is being reloaded. Next, for each secret, if the version number of the secret is different from the version number of the corresponding new secret to be loaded, the new secret and its version number are loaded. Next the version number of the set of secrets of the cryptographic module is set to the version number of the set of new secrets.

Abstract: The invention relates to a method for modifying a set of secrets in a crypto-graphic module. The cryptographic module ensures that the loading of a secret is either complete or null and void. The module enables a reading of a version number for each secret. The module includes information indicating a version number corresponding to the set of secrets. The method of the invention includes a first step during which, if the version number of the set of secrets is equal to a version number that requires the loading of a set of new secrets, the version number of the set of secrets in the cryptographic module is made equal to a distinctive number that determines that the cryptographic module is being uploaded. The method comprises a second step during which, for each secret and if the version number of said secret is different from the version number of the corresponding new secret to be downloaded, the new secret and the version number thereof are loaded.

Abstract: The invention relates to a method of customizing a security component in an unprotected environment. The method according to embodiments of the invention includes: inserting a first secret K0 into said security component, said insertion implemented in a secure domain under the responsibility of the manufacturer of the security component; generating an application secret K and generating a customization cryptogram [K]K0 obtained by encrypting the application secret K with the first secret K0, in an application secure domain under the responsibility of the holder of the security component; and customizing the security component by inserting the customization cryptogram [K]K0 into said security component, said customization step being implemented in an application domain. The invention applies to components of secure access module type.

Abstract: The invention relates to a system for secure transactions of card-borne value units. The system comprises a card peripheral device for setting up a link with the card and comprising a transparent mode, a terminal linked to the card peripheral device, a host device linked to the terminal. The host device comprises a transactional application suitable for processing the value units on the card and cryptographic means making it possible to read and/or write values units and other information on the card. The card peripheral device operates in transparent mode. The terminal redirects the information originating from or addressed to the card peripheral device to the host device. The host device dialogs with the card via commands and data interchanges. In particular, the invention applies to the topping-up of a chip card, notably from computer means available to the user in possession of said card and an ordinary chip card reader.
