Abstract:
The present invention concerns the implementation of end-to-end security for the communication between a low cost card reader and the remote server. The purpose of the present invention is the establishment of a secure channel between the card reader and the remote server through an un-trusted communication device (e.g. a smart phone or a tablet) that is intrinsically resistant to some basic differential side-channel analysis in a context where there is no secure random number generator and no source of entropy in the card reader, while providing the following characteristics: - Mutual authentication between the card reader and the server - Secure channel based on session keys such that the keys of the secure channel related to a past transaction cannot be re-played, or the session keys of a future transaction cannot be pre-computed by the card reader and later re-use by the card reader in a legitimate transaction.
Abstract:
The smart card according to the invention is manufactured by injection moulding plastic material in a mould comprising a shearing assembly comprising a punch (41) and a die (42) that slide in the opposite walls (31, 32) respectively of the mould, in a sliding direction that is orthogonal to the overall plan. The card is at least partially sheared in the attaching zones (40) between a card body in a first format (3) and a card body (4) in a second smaller format, by simultaneously displacing the die and the punch, between which the card body (4) is held, in one direction and then in the opposite direction to bring the card body (4) in the second format back to its initial position in relation to the card body (3). Application particularly for the manufacturing of multi-format smart cards.
Abstract:
A method for protecting data on a mass storage device, said device comprising a security module and a data storage area configured to be switched between a protected state, in which accessing the data storage area is forbidden and an unprotected state, in which accessing the data storage area is authorized, wherein switching said data storage area from the protected state to the unprotected state comprises steps of : • sending (20) a request to a remote server; • receiving (22) a one-time password on a communication device, in response to the sent request; • providing (26) said received one-time password to the security module; • authorizing (30) access to the data storage area by the security module, once said provided one-time password is deemed valid by said security module.
Abstract:
The present invention relates to a countermeasure method against side channel analysis for cryptographic algorithm using Boolean operations and arithmetic operation. To protect a cryptographic algorithm combining Boolean and arithmetic instructions against first order side channel analysis, it is necessary to perform conversions between Boolean masking and arithmetic masking. The present invention proposes a new conversion method from arithmetic masking to Boolean masking, using only one precomputed table T. Said table T being configured so that to convert from arithmetic to Boolean masking k-bit nibble by k-bit nibble for integers having a size greater than k bits while adding a masked carry from the modular addition to the nibble.
Abstract:
The invention relates to a method for determining anonymously a given user's data among a plurality of user's data in a network, said network comprising a server, a gateway, said user's data adapted to be exchanged between the gateway (20) and the server (10), said gateway (20) comprising a secure element (22), characterized in that it comprises sending public keys of the gateway associated to each user's data to the server and sending to the gateway public keys of the server associated to each user's data.
Abstract:
The invention relates to an electronic capacitive touch screen emulator (1) that comprises a conductive plate (CS) being intended to be in contact or very close to a capacitive touch detection device (2). The conductive plate (CS) is connected to a diode-based commutative unit (SW). The modification of impedance provided by the commutative unit (SW) when it is switched on changes the electric field around the conductive plate (CS) and thus provides the emulation of presence of a human fingertip.
