WebFirst, using optical fault induction attacks as recently publicly presented by Skorobogatov and Anderson \cite {SA}, we present an implementation independent fault attack on AES. This attack is able to determine the complete 128 -bit secret key of a sealed tamper-proof smartcard by generating 128 faulty cipher texts. WebIllumination of a target transistor causes it to conduct, thereby inducing a transient fault. Such attacks are practical; they do not even require expensive laser equipment. We have …
