And selecting the security module with the highest score from the plurality of security modules as a target security module.
Wherein w4 is the weight of the selection confirmation value of Type A, SAK Practice of The selection confirmation value of Type A required by the card swiping equipment, SAK (Security application Key) is the selection confirmation value of Type A corresponding to the security module, w5 is the weight of the frame waiting time integer value, FWI (full Fidelity interface) Practice of The frame waiting time integral value required by the card swiping equipment, FWI is the frame waiting time integral value corresponding to the security module, w6 is the weight of the starting frame protection time integral value, SFGI Practice of And the SFGI is the starting frame protection time integral value corresponding to the security module. For w4, w5 and w6The specific value can be determined according to the actual situation.
For example, card swiping equipment in subway card swiping scene, and adopted FWI Practice of Less than or equal to F (which is a 16-ary value), SFGI Practice of Less than or equal to F, SAK Practice of Equal to 0X or 2X;
card swiping equipment in business excess card swiping scene, and FWI adopted by card swiping equipment Practice of Less than or equal to 7,SFGI Practice of Less than or equal to 7,SAK Practice of Equal to 2X;
card swiping equipment under taxi/handheld POS (point of sale) card swiping scene and FWI (full flash architecture) adopted by card swiping equipment Practice of Equal to 7,SFGI Practice of Equal to 0,SAK Practice of Equal to 2X;
in this case, the second formula can be expressed as:
Score2＝0.7×(SAK practice of /SAK)+0.2×(FWI Practice of /FWI)+0.1×(SFGI Practice of /SFGI)
