Other TRNG approaches? Security Seminar Sept. 30 2008 -XKCD

Lower temperature to break TRNG? ,[object Object],[object Object],[object Object],[object Object],[object Object]

Change temperature to break ID? ,[object Object],[object Object],[object Object],[object Object],[object Object]

Attack by controlling supply? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Size of box represents noise margin of each state Superimposed VTC of the two cross coupled inverters (at 2 different supplies) Only “0” state is stable at Vdd = 100mV

Attack by NBTI ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],*Burn-in: “turn on chip, write in 0, bury DE2 in laundry so that it gets hot, and then go party for 1.7E5 seconds”
