In practical application, can also generate at least one random number by target meeting terminal, platform generates at least one random number, platform and
Target meeting terminal synchronizes random number generated, and according to identical logical process mode, obtain an identical target with
Machine number.
In embodiments of the present invention, the digit of the generating mode to target random number and target random number does not limit
It is fixed.Preferably, in order to further ensure the safety of symmetric key, can be screened by random number, ensure target terminal equipment and
The target random number that platform is held is different from the target random number that target terminal equipment last time multipoint conference obtains, and can also lead to certainly
It crosses and is compared with other of target meeting corresponding target random number of terminal of attending a meeting, so that terminal of finally each attending a meeting corresponds to mesh
Mark random number is all different.I.e. platform finally hold about the target random number of target meeting and the terminal of attending a meeting of target meeting
Quantity is identical, and different between each target random number.
