In an actual application scenario, the first key corresponding to the obtained target electric scooter and the second key corresponding to the target mobile terminal device may specifically be: random permutation of 16 values (0 x00-0x 0F).
The key set is the set of all keys.
A random permutation of 16 values totals 20922789888000 combinations:

In the communication data encryption and decryption method applied to the electric scooter provided by the embodiment of the application, ASCII codes corresponding to Bluetooth addresses are adopted for operation, and then a table is searched to obtain a key (Key type).

In the practical application scenario, the key calculated in the step S102 is:
Key[16]={0x0F,0x03,0x0E,0x0B,0x06,0x08,0x04,0x01,0x02,0x0C,0x0D,0x0A,0x05,0x00,0x09,0x07}
0->F 1->3 2->E 3->B 4->6 5->8 6->4 7->1 8->2 9->C A->D B->A C->5 D->0 E->9 F->7
first plain text: tab [3] = {0x0f,0x12,0xe3}
