Abstract
The disclosure relates to a method for transmitting data and to a corresponding method for receiving data. According to the disclosure, in the method for transmitting data, a cryptographic processing operation is performed on the data to be transmitted, after this data has been pre-subdivided into blocks of data, and a tag representing each block of encrypted data is computed. The tag is then transmitted in such a way that a hacker in not able to reproduce a correct transmission of tags. The method of reception, for its part, ensures that when an incorrect tag is received (because of a hacking attempt), the processing of the data blocks is not immediately stopped but a differential processing is implemented in order to jam an attempt to analyze the behavior of the receiver.
