The present disclosure relates to a circuit and method for determining a sign indicator bit of a binary datum including a step for processing of the binary datum masked with a masking operation, and not including any processing step of the binary datum.

An embodiment relates to a method for processing masked data using a processor comprising an arithmetic and logic unit, in which the masked data remain masked during their processing in the arithmetic and logic unit.

The present disclosure relates to a device and method for processing masked binary data values, comprising extracting and inserting a first part of a first masked binary data value in a second masked binary data value, in which the first and second masked binary data values stay masked throughout all of the processing.

A first input share value, a second input share value, and a third input share value may be received. The first input share value may be converted to a summation or subtraction between an input value and a combination of the second input share value and the third input share value. A random number value may be generated and combined with the second input share value and the third input share value to generate a combined value. Furthermore, a first output share value may be generated based on a combination of the converted first input share value, the combined value, and additional random number values.

A multi-word multiplier circuit includes an interface and circuitry. The interface is configured to receive a first parameter X including one or more first words, and a second parameter Y including multiple second words. The second parameter includes a blinded version of a non-blinded parameter Y that is blinded using a blinding parameter A.sub.Y so that Y=Y+A.sub.Y. The circuitry is configured to calculate a product Z=X.Math.Y by summing multiple sub-products, each of the sub-products is calculated by multiplying a first word of X by a second word of Y, and subtracting from intermediate temporary sums of the sub-products respective third words of a partial product P=X.Math.B.sub.Y, B.sub.Y is a blinding word included in A.sub.Y.

Systems for vehicles are disclosed using simplified state machines. For one example, a data processing system for a vehicle includes a plurality of subsystem nodes interconnected by a network topology. Each subsystem node includes a transceiver and micro-controller coupled to the transceiver. The micro-controller is configured to obtain an atomic machine state bit vector. Each bit of the atomic bit vector describes a state of the vehicle used by a state machine operating within the vehicle. The micro-controller multiplies a first bit vector mask with the atomic machine state bit vector to obtain a first result. The first result identifies first states of interest. The micro-controller determines a next state for the state machine based on the identified first states of interest. The micro-controller performs a function for the vehicle based on the determined next state. The atomic machine state bit vector can be updated based on the determined next state and distributed within the vehicle.

Some embodiments are directed to an electronic computation device (100) arranged for obfuscated execution of a multiplication. The device comprises a storage (120) arranged for storing multiple variables used in the execution of an arithmetic operation, a variable (x: y; 2) of the multiple variables being represented as multiple multiplicative shares (X=(x.sub.0, x.sub.1, . . . , x.sub.m1); Y=(y.sub.0, y.sub.1, . . . , y.sub.m1); 20), said multiplicative shares being represented in the storage as multiple additive shares (x.sub.i=(x.sub.i,0,x.sub.i,1, . . . , x.sub.i,n1); Yi=(y.sub.i,0,y.sub.i,1, . . . , y.sub.i,n1); 210, 220).
