    摘要： A camouflaged FinFET is disclosed. The camouflaged FinFET comprises a fin and a gate, disposed over and perpendicular to the fin. The fin includes a source region of a first conductivity type, a drain region of the first conductivity type, a channel region of a second conductivity type, the channel region disposed between the source region and the drain region, and a camouflaged fin region of the second conductivity type, the camouflaged Fin region at least partially rendering the camouflaged FinFET in an always-on condition and having a planar layout substantially indistinguishable from a fin region of an uncamouflaged FinFET.

    摘要： In an aspect, a method can include generating a cyclic redundancy check code for a binary data item, using a generator polynomial; and masking, using polynomial addition, the binary data item with a binary mask. The method can also include at least one of: storing, by a microcircuit, the masked binary data item in a memory of an electronic device; or transferring, by the microcircuit, the masked data item to another device. The cyclic redundancy check code for the binary data item can be generated from the masked binary data item to prevent discovery of the binary data item by a side-channel attack during the generating the cyclic redundancy check. The binary mask can be a multiple of a random number and the generator polynomial, such that respective cyclic redundancy check code of the masked data item and the binary data item have a same result.

    摘要： A cryptographic data processing method, implemented in an electronic device including a processor, the method including steps of providing a point of an elliptic curve in a Galois field, and a whole number, and of calculating a scalar product of the point by the number, the coordinates of the point and the number having a size greater than the size of words that may be processed directly by the processor, the scalar multiplication of the point by the number including steps of: storing scalar multiples of the point multiplied-by the number 2 raised to a power belonging to a series of whole numbers, setting a resulting point for each non-zero bit of the first number, adding the resulting point and one of the stored multiple points, and providing at the output of the processor the resulting point as result of the scalar product.

    摘要： In a general aspect, a method can include establishing a contactless communication channel with a contactless transaction terminal and receiving a command from the contactless transaction terminal. The command can include an identifier of an application. The method can also include selecting, in a table in response to the command, an instance identifier corresponding with an instance of the application from a plurality of instance identifiers corresponding, respectively, with different instances of the application. Each instance identifier can be associated with a state indicator, and the state indicator associated with the selected instance identifier can specify that the corresponding instance of the application is in a selectable state. The method can further include transmitting the command to the corresponding instance of the application; activating, in response to receiving the command, the corresponding instance of the application; and executing, by the activated instance, a contactless transaction with the contactless transaction terminal.

    摘要： A method for sending data by inductive coupling includes: extracting an antenna signal from an antenna circuit, extracting from the antenna signal a first periodic signal, producing a second periodic signal by way of a synchronous oscillator, placing the oscillator in a free oscillation mode and applying to the antenna circuit the second periodic signal, modifying the impedance of the antenna circuit, restoring the amplitude of the antenna signal, then resynchronizing the oscillator on the first periodic signal.

    摘要： A system for determining the start of a match of a regular expression has a special state table which contains start state entries and terminal state entries; a plurality of start state registers for storing offset information indicative of the start of a match of the regular expression; a deterministic finite state automaton (DFA) next state table which, given the current state and an input character, returns the next state. The DFA next state table includes a settable indicator for any next state table entry which indicates whether to perform a lookup into the special state table. A compiler loads values into the special state table based on the regular expression.
