摘要： Biometric data relating to a biological part are processed by obtaining, on the one hand, a first set of transformed biometric data (f(B1)) by applying at least one irreversible transformation to a first set of biometric data (B1), and, on the other hand, a second set of transformed biometric data (f(B2)) by applying said transformation to a second set of biometric data (B2). Thereafter, a decision is made as to whether the second biometric data set corresponds to the first biometric data set on the basis of a comparison between the first transformed biometric data set and the second transformed biometric data set, said comparison being performed at the bit level of a digital representation of said first and second transformed biometric data sets as a function of an error corrector code word.

摘要： In an RF label identification system comprising a label reader and a plurality of labels, a unique and secret identifier being associated with each label, a first random number is sent from a label to the reader. A second random number is then sent from the reader to the label. In the RF label, a value of the encrypted identifier is then obtained by generating third and fourth random numbers in accordance with a probabilistic rule, by transforming the first and second random numbers in accordance with a determined function and by combining the identifier with the first and second random numbers, with the first and second transformed numbers and with the third and fourth random numbers. The value of the encrypted identifier is sent to the reader. After N repetitions of the above process, the reader identifies the RF label as a function of the N values of the encrypted identifier received, of the determined function, of the N first and second random numbers and of the probabilistic rule.

摘要： The invention relates in particular to a method for securing the execution of a cryptographic algorithm (ALG) against passive sniffing, the method implementing masking (MSK) of data processed by the cryptographic algorithm. The masking (MSK) of said data includes a linear encoding step such as x′=x·L+c, in which x is the data to be masked, x′ is the corresponding masked data, c is a code word included in a linear code C, and L is a matrix made up of linearly independent vectors not included in the linear code C. The invention also relates to a device (SC) implementing such a method.
