PROCEDE DE TRAITEMENT DE DONNEES SECURISE, BASE NOTAMMENT SUR UN ALGORITHME CRYPTOGRAPHIQUE

The method involves executing an encryption algorithm (F k) by utilizing a random value (A1), and generating an output data (S) from an input data (E). The encryption algorithm (F k) is executed by utilizing a random value (A2) which is different from the random value (A1), and a verification data (...

Zusammenfassung:	The method involves executing an encryption algorithm (F k) by utilizing a random value (A1), and generating an output data (S) from an input data (E). The encryption algorithm (F k) is executed by utilizing a random value (A2) which is different from the random value (A1), and a verification data (V) is generated. The data (V) is compared with the data (S) for verification of the correct execution of the algorithm (F k). Independent claims are also included for the following: (A) a data processing device (B) a computer program having instructions to implement a secured data processing method.
