    摘要: A method for routing data in a chipset comprising at least one host processor and an RFID-type contactless data send/receive interface includes, in response to a command for opening a data path sent by a source point located in the host processor and designating a destination point located in the contactless data send/receive interface, defining a data path linking the source point to the destination point by allocating to the data path a routing channel number and by saving in a routing table the routing channel number and routing parameters comprising at least one identifier of the source point and one identifier of the destination point, and sending to the destination point data supplied by the source point by encapsulating the data in a frame having a header field comprising the routing channel number.

    摘要: A countermeasure method in an electronic component implementing an asymmetric private key encryption algorithm includes generating a protection parameter, calculating, using a primitive, an intermediate data from the protection parameter, dividing the binary representation of the private key into several binary blocks, transforming each binary block using the protection parameter and, for each transformed binary block, performing an intermediate calculation using the primitive, and calculating an output data by combining the intermediate data with the intermediate calculations.

    摘要: A method of protecting a microcircuit against attacks aimed at discovering secret data used on the execution, by the microcircuit, of an encryption algorithm includes generating at least one protection parameter for the secret data and modifying the execution of the encryption algorithm through that protection parameter. Generation of the at least one protection parameter includes defining a function generating, by successively applying to at least one secret parameter which is stored in memory, a sequence of values which can only be determined from that secret parameter and that function, and to generate the protection parameter in a reproducible way from at least one value in that sequence.

    摘要: A contactless integrated circuit is provided that includes a RFID communication interface, a UHF communication interface, a data processing unit, an interface multiplexer, a communication mode detection circuit, a first modulation and demodulation circuit, a second modulation and demodulation circuit, and a multiplexer demultiplexer circuit. The interface multiplexer couples the data processing unit to the RFID or UHF communication interfaces. The multiplexer demultiplexer circuits are driven by mode signals delivered by the communication mode detection circuit, to link the data processing unit to one of the two modulation and demodulation circuits.
