Abstract:
The invention relates to a personal token running a series of applications (A, B, C, D, E), characterized in that it comprises a thread controller (TC) which transmits data from the applications (A, B, C, D, E) to an external device (TS) in a cyclic way, a cycle being constituted of a series of data transfers (1A, 2A, 3A ) from the applications (A, B, C, D, E) and to the external device (TS), a cycle comprising a respective number of data transfers dedicated to each respective application (A, B, C, D, E) which is different according to the respective application (A, B, C, D, E), the number of data transfers for a respective application (A, B, C, D, E) in a cycle corresponding to a priority level of the application (A, B, C, D, E) as taken into account by the thread controller (TC).
Abstract:
To reduce the power consumption of the chip card of a mobile telephone according to the power supply status of the said telephone, the electrically erasable memory is managed according to the power supply status of the mobile device. Are thus proposed a memory management process for a removable object placed in a mobile device, a mobile device and a chip card. The removable object includes at least a primary non-volatile memory and a secondary non-volatile memory. The secondary memory is electrically erasable in blocks. The removable object is informed by the mobile device of the power supply status of the mobile device. According to the power supply status of the mobile device, the erasing of the secondary memory is always authorised (31), partially authorised (35, 36) or forbidden (34).

The invention relates to a cryptographic mechanism and to a cryptographic device incorporating such cryptographic mechanism. The cryptographic mechanism offers a better resistance to side channel attacks than that of known cryptographic mechanisms by incorporating a new type of masking mechanism.
Abstract:
The invention relates to a system comprising a network device (NSC), a host computer (HOST) and a remote server (SRV). The host computer (HOST) and the network device (NSC) are connectable through a network. The host computer (HOST) and the remote server (SRV) are connectable through the Internet. The network device (NSC) comprises a web server accessible from the host computer (HOST). The network device (NSC) is set to store a user's authentication credential. The host computer (HOST) is set to display a web page produced by the remote server (SRV) to the user. The remote server (SRV) is set to include a login link in said web page, the login link pointing to said web server. The web server is set to display a login page to the user on the host computer (HOST) when the user clicks on said login link, in order to authenticate the user. Upon authentication of the user, the network device (NSC) is set to send the user's authentication credential to the remote server (SRV) in order to authenticate the user to the remote server (SRV).

Abstract:
One delay circuit is inserted in open loop inside a clock recovery circuit for improving the accuracy of clock recovery. One oscillator signal f(0) to f(2 i -1) is provided with a basic Step of Time. A rational number of Step of Time corresponding to a bit-duration is measured inside a received flow of bits. The oscillator signal f(0) to j(2 i -1) is transformed into a clock signal CK having active edges of said clock signal in phase with at least one oscillator signal f(0) to f(2 i -1), two consecutive active edges being separated by a time duration proportional to the integer part of the number of Step of Time. A time delay is computed proportional to the fractional part of the number of Step of Time. The next active edge of the clock signal CK is delayed of said computed delay.
