Abstract: Multi-bits DEMA attack is an effective side-channel attack method on cryptographic algorithm. Based on the analysis of the Hamming-weight model and the principle of DEMA, the paper proposes a method of multi-bits DEMA peak simulation analysis. Then the paper makes simulation analysis and realizes the multi-bits DEMA attack on the AES algorithm. The result proves the effective of the DEMA peak simulation analysis.
