Prevent Hackers From Using Side Channel Power Attacks To Determine The AES Encryption Key

Weyna; Lisa, Rooks; John W.
Summary
This invention provides an technology for obscuring power consumption of hardware implementation of the AES algorithm. Two distinct methods for accomplishing this are as follows: 1) Simultaneously executing a processor floating point operation while executing the AES algorithm, 2) Circuit layout techniques that negate power analy key hacks. These methods prevent hackers the opportunity to determine the AES key value during a side channel power attack.
