Abstract:
The method according to this invention concerns a method to secure an electronic assembly including processing means and storage means (7, 11) containing a program to be executed. The method consists in associating with at least one data item stored in said means (7,11) at least one identification attribute used to classify said data item into a data family. This invention also concerns the electronic module in which said method is implemented and the card comprising said module.
Abstract:
The method according to this invention concerns a method to secure the write in storage means of an electronic assembly comprising information processing means, said method comprising an atomic write process to write data recorded in a write log. The method consists in checking a sequence of atomic writes in said storage means by setting in said write log one or more indicators in memory as proof of one of more successive writes recorded in said log. This invention also concerns the electronic module in which said method is implemented and the card comprising said module.
Abstract:
The method according to this invention concerns a method for automatically generating cryptographic algorithms with optional supplementary data, said algorithms comprising two different zones: external algorithm secrecy zone, in external parts of the algorithm exposed to side-channel analysis, and an internal purely cryptographic zone that is not exposed to side-channel analysis, such that in the algorithm secrecy zone, the code of the algorithm is locally made of random (or pseudo-random) and independent sequences of instructions and/or table-lookups chosen from some fixed set of instructions and random constants, with some fixed prescribed probability distribution, and such that the internal cryptographic security zone can be any cryptographic algorithm or method that handles algorithmic security only and does not have to be protected against side-channel attacks.

Abstract:
A card body comprises a first card body (ID-1 card 1), a second card body (plug-in card 2) and a third card body (mini card 3). The first card body has a first shape (ID-1 shape). The second card body comprises a second shape (plug-in shape). The first card body encompasses the second card body. The third card body comprises a third shape (mini shape). The second card body encompasses the third card body. The third card body has a cavity for receiving an electronic module. A first boundary separates the first shape (ID-1 shape) from the second shape (plug-in shape), and comprises a first number of apertures (5, 6, 7, 17, 18) and a first number of notches (19 and 20) defining a first mechanical inter-card body coupling strength (link between ID-1 card 1 and plug-in card 2). A second boundary separates the second shape (plug-in shape) from the third shape (mini shape), and comprises a second number of apertures (21) and a second number of notches (11, 12, 13, 14, 15, 16) defining a second mechanical inter-card body coupling strength (link between plug-in card 2 and mini card 3). A cumulated length of the first number of apertures (5, 6, 7, 17, 18) is greater than a cumulated length of the second number of apertures (21) and a cumulated length of the first number of notches (19 and 20) is lesser than a cumulated length of the second number of notches (11, 12, 13, 14, 15, 16) so that the second mechanical coupling strength is greater than the first mechanical coupling strength.
Abstract:
The network includes a central network server (10) and a plurality of mobile stations (20), each mobile station (20) including a mobile equipment (22) and a user-specific module (24). Radio communication (30) takes place between the network server and the mobile equipment after authentication from the user module. The method includes successive steps of: a) issuing by the user module (24) a request for obtaining maintenance data, b) transmitting said request from the user module to the mobile equipment, c) obtaining maintenance data by the mobile equipment, d) transmitting said maintenance data from the mobile equipment to the user module, e) processing said maintenance data within the user module (24), e.g. updat-ing a log record and/or checking maintenance data over predetermined transmission quality criteria, in particular for f) transmitting said processed data (MESSAGE/ALERT) from the user module to the mobile equipment, typically in the form of a SMS, and g) remotely transmitting said processed data (MESSAGE/ALERT) from the mobile equipment to the network server, in particular for correcting radio transmis-sion parameters of the wireless network.
Abstract:
A chip card comprises a card body with a recess (10) formed therein and a chip module embedded in the recess. The recess includes two concentric cavities with an upper cavity (12) and a lower cavity (14), the upper cavity having a peripheral outline corresponding to the peripheral outer shape of the module and the lower cavity having a peripheral outline the dimensions of which are smaller than the respective dimensions of the upper cavity so as to form a peripheral shoulder supporting the backside of the chip module. The recess further includes at least one stress-relieving cavity in communication with the inner space of the recess (10), such as a notch (32) in communication with the lower cavity (14).

Abstract:
A method of controlling access to a secure service by means of a removable security device comprises the steps of connecting said removable security device with a system capable of performing a secure service; detecting that a connection between said removable security de-vice and said device capable of performing a secure service has been established; disconnecting said removable security device from said system capable of performing a secure service; re-connecting said removable security device with said system capable of performing a secure service; detecting that a re-connection between said removable security device and said system capable of performing a secure service has been established; and granting a requested secure service if the establishment of a re-connection between said removable security device and said system capable of performing a secure service has been detected.
