Method and device for transmitting verification information

A device for transmitting verification information comprising:

• a processor;
• and
• a memory;
• wherein the processor executes instructions stored in the memory to implement:
• a separation module is configured for separating the verification information into multiple sub-verification information, and numbering the multiple sub-verification information according to sequence numbers of the multiple sub-verification information in the verification information;
• a generation module is configured for calculating each of multiple pieces of packet length information according to each of the sequence numbers corresponding to the multiple sub-verification information, and generating sets of multicast frames according to the multiple sub-verification information and the multiple pieces of packet length information corresponding to the sequence numbers of the multiple sub-verification information;
• wherein, each of the multiple pieces of packet length information is a packet length of each of the sets of multicast frames;
• a selection module is configured for selecting one set of multicast frame from the sets of multicast frames, and encapsulating a length of the verification information in the one set of multicast frame selected;
• a transmission module is configured for transmitting the sets of multicast frames on condition that an overall length of the multiple sub-verification information in the sets of multicast frames received by a recipient is equal to the length of the verification information in the one set of multicast frame selected, recombining the multiple sub-verification information to obtain the verification information according to the sequence numbers of the multiple sub-verification information.

A device for receiving verification information comprising:

• a processor, and
• a memory;
• wherein the processor executes instructions stored in the memory to implement:
• a first obtaining module, is configured for obtaining multiple pieces of packet length information and multiple sub-verification information in the sets of multicast frames, and calculating each of sequence numbers of the multiple sub-verification information based on each of the multiple pieces of packet length information;
• a second obtaining module, is configured for obtaining a length of the verification information from a selected set of multicast frame of the received sets of multicast frames;
• a recombining module, for on condition that an overall length of the multiple sub-verification information in the sets of multicast frames received by a recipient is equal to the length of the verification information in the sets of multicast frames, recombining the multiple sub-verification information to obtain the verification information according to the sequence numbers of the multiple sub-verification information.
