Abstract:

With the aggressive scaling of VLSI technology and moving towards smaller feature sizes, various design robustness concerns continue to arise. Among them, aging effects in CMOS devices are one of the major challenges in nanotechnologies. Aging changes the specifications of transistors over time and in turn, the timing and power consumption of the underlying devices. 

Although aging mechanisms and related mitigation schemes have received the lion’s share of attention from the reliability perspective in recent years, their impact on the security of devices, in particular cryptographic devices, is yet to be investigated thoroughly. However, in practice, such aging-induced change of the delay and power consumption of the device can affect the success of the attacks built upon exploiting unintentional leakages from the device such as its power consumption or timing characteristics.

This talk first focuses on the aging-induced security concerns in cryptographic devices and how aging can affect the success of the physical attacks targeting these devices. Then a number of aging-resilient security solutions are presented. Moreover, a malicious aging acceleration attack that can target a broader range of integrated circuits including microprocessors is presented.
