The article analyzes the CMOS logical gate's electric current characteristic under the active status, establishes the electromagnetic information leakage hamming distance model in registers level. Aimed at the Data Encryption Standard(DES) cryptographic system realized by the P89C668 microcomputer, Correlation Electromagnetic Analysis (CEMA) algorithm was described, the choosing of attack point D and the computational method were analyzed, an attack experiment was processed by CEMA, thereby obtaining 48-bits sub-key of the 16(th) round of DES. The result shows that EM information leakage exist...
