    The key of side channel collision attack lies in collision detection process.Based on the research of side channel collision attack, we summarise the collision model of Feistel structure cipher algorithm.Through the improvement of collision detection process, we realisethe least absolute deviations-based collision detection technology.Then the side channel collision attack is executed against the Data Encryption Standard ( DES) cryptographic algorithm implemented on the basis of field-programmable gate array ( FPGA) .By the use of power acquisition platform, the validity of least absolute deviations-based collision detection technology is verified.
