Protection against a side-channel analysis

A method for executing, by a circuit, an operation combining first and second input data and providing an output data of the same size, may include generating from the first input data a first input set including all possible data in relation to a size of the first data, generating... Eshard

Method for protecting substitution operation against side-channel analysis

A method for executing an operation by a circuit, may include using a first mask set of mask parameters including a same number of occurrences of all possible values of a word of an input data in relation to a size thereof, using an input set including for each mask... Eshard

Methods and devices against side-channel analysis

A method for executing an operation whereby a first input data, may be combined with a second input data, may include: defining data pairs whereby each data of a first input set is associated with a respective data of a second input set, the data in the first and second... Eshard

Methods and devices against a side-channel analysis

A method for executing by a circuit a bit permutation operation by which bits of an input data are mixed to obtain an output data including at least two words, may include: generating a first mask set including mask parameters, the mask set having one word column per word of... Eshard

Protection against a side-channel analysis

A method for executing an operation by a circuit, may include executing a first operation to process an input data, the circuit generating during the execution of the first operation a first signal, and executing in the circuit a second operation receiving the input data and configured to add to... Eshard

Methods for protecting substitution operation using substitution table against a side-channel analysis

A method for executing by a circuit a substitution operation such that an output data may be selected in a substitution table using an input data as an index. The substitution operation may be performed using a new masked substitution table. The input data may be combined by XOR operations... Eshard

Method of testing the resistance of a circuit to a side channel analysis

In a general aspect, a test method can include acquiring a plurality of value sets, each including values of a physical quantity or of logic signals, linked to the activity of a circuit to be tested when executing distinct cryptographic operations applied to a same secret data, for each value... Eshard

Method of testing the resistance of a circuit to a side channel analysis of second order or more

A test method can include: acquiring a plurality of value sets including measurements or signals corresponding with activity of a circuit when executing a set of cryptographic operations on secret data, for each value set, selecting at least two subsets of values, computing combined values and counting occurrence numbers of... Eshard

Method of testing the resistance of a circuit to a side channel analysis of second order or more

A test method for a circuit can include: acquiring a plurality of value sets including values corresponding to activity of the circuit when the circuit executes an operation of an operation set of distinct cryptographic operations applied to a same secret data, selecting at least two subsets of values in... Eshard

Method of testing the resistance of a circuit to a side channel analysis

The present invention relates to a test method of a circuit, comprising: acquiring a plurality of value sets comprising values of a physical quantity linked to the activity of a circuit to be tested when the circuit executes an operation of a set of distinct cryptographic operations applied to a... Eshard

Method of protecting a circuit against a side-channel analysis

In a general aspect, a method for executing, by a circuit, an operation receiving an input data and providing an output data includes: selecting a substitution element in a substitution table as a function of the input data or an intermediary data, the substitution element being a first data set,... Eshard

Method of protecting a circuit against a side-channel analysis

In a general aspect, a method for executing a target operation combining a first input data with a second input data, and providing an output data can include generating at least two pairs of input words each comprising a first input word and a second input word and applying to... Eshard
