METHOD FOR OPTIMIZING THE EXECUTION OF A FUNCTION WHICH GENERATES AT LEAST ONE KEY WITHIN AN INTEGRATED CIRCUIT DEVICE

摘要

The present invention relates to method for optimizing the execution of a function (OP1), said function (OP1) generating at least one key (k1) and being performed within an integrated circuit device (IC), said integrated circuit device (IC) comprising a buffer (BUFF), wherein said method (MTH) comprising: - upon reception of a command (CMD) by said integrated circuit device (IC): - computing at least one data (p1) from which said at least one key (k1) will be generated; - storing said at least one data (p1) in said buffer (BUFF); - executing said command (CMD).
