This is a set of traces from a cryptographic device Xilinx Spartan XC3s5000 running at a frequency around 33 MHz and collected by an oscilloscope Agile infiniium DSO80204B 2Ghz 40GSa/s. The cryptographic device implemented the bloc cipher ‘Triple Data Encryption Algorithm’ and the traces have been reduced with the feature selection
mRMR in order to obtain only 300 components from 20001 initially.
powerC is a matrix with 256 rows and 301 columns. From the first to the 300_th component of powerC, each row is a trace. The secret to retrieve by these traces is a bit of the secret key used by the cryptographic device. The value of this bit is given by the 301_th component of powerC.
