The invention provides a group message interaction realization method, which comprises the following steps of: a communication
server authenticates the received group message instruction transmission right of a source user, authenticates the group message instruction receiving rights of group members after the group message instruction transmission right of the source user passes the
authentication, and transmits a group message and the information of each member in a member
Hash table corresponding to a found
group identifier to a synchronous storage
server after the group message instruction receiving rights of the group members pass the
authentication; and after receiving the group message, the synchronous storage
server stores and updates the group message with the
group identifier, and transmits the updated group message with the
group identifier to each group member in the member
Hash table corresponding to the group identifier. The invention provides a group message interaction realization
system. By the method and the
system, secure group communication and multi-member
secure communication can be realized without downloading and installing any
software.
