METHOD FOR SECURING A CONDITIONAL CONNECTION, INFORMATION CARRIER, SOFTWARE, SECURED SYSTEM, AND SECURITY PROCESSOR FOR SAID METHOD |
摘要 |
<p>The invention relates to a conditional connection that permits the execution of a specific processing of a datum D if the Boolean expression between one or more operands is satisfied, or otherwise prohibits the execution of said processing. The method for securing the conditional connection comprises: a) calculating (36, 48, 50) a datum D' from the datum D and the operands of the Boolean expression so that the datum D' is identical to the datum D if and only if the Boolean expression is satisfied and so that the datum D' has another so-called invalid value if the Boolean expression is not satisfied, the datum D' being coded over a plurality of bits; and b) using the datum D' in place of the datum D upon each execution of the specific processing.</p> |
