Spply voltage glitches are a well-known fault njection method used to attack electronic circuits. The aim of this paper is to identify the specific threats of mixed signal systems and to provide some solutions to ensure their security. Indeed, many Systems on Chip use both analog and digital circuits but, most of the time, the security of such application is considered only from an exclusively digital...
Techniques using modification of power supplies to attack circuits do not require strong expertise or expensive equipment. Supply voltage glitches are then a serious threat to the security of electronic devices. In this paper, mechanisms involved during such attacks are analyzed and described. It is shown that timing properties of logic gates are very sensitive to power glitches and can be used to...
A study on power consumption of a digital synchronous circuit in advanced CMOS technology is performed. These technologies target low power applications allowing accurate power analysis. A model of power signature is developed to identify data related consumption using current consumption and power delivery network capacitance at design phase. In addition to digital power characterization tool, device...
