Abstract: The present invention relates to a countermeasure method against side channel analysis for cryptographic algorithm using Boolean operations and arithmetic operation. To protect a cryptographic algorithm combining Boolean and arithmetic instructions against first order side channel analysis, it is necessary to perform conversions between Boolean masking and arithmetic masking. The present invention proposes a new conversion method from arithmetic masking to Boolean masking, using only one precomputed table T. Said table T being configured so that to convert from arithmetic to Boolean masking k-bit nibble by k-bit nibble for integers having a size greater than k bits while adding a masked carry from the modular addition to the nibble.

Abstract: In a call redirection method, an application of a second telecommunications terminal requests one of the active numbers in the security element of a first terminal. The application transmits a request for an active telephone number in the security element to its operator, and the latter retransmits it to a manager of the security element having knowledge of the active subscription in the security element. At least one subscription is inactive and at least one subscription is active. Each subscription has a corresponding call number. A call number is called an active call number if the corresponding subscription is active, and a call number is called an inactive call number if the corresponding subscription is inactive. The method includes composing the telephone number corresponding to one of the active subscriptions or prompting the user of the second terminal to validate the call to one of these active numbers.
