Embodiment 1

[0060] When user A uses the Fetion client for instant messaging on the mobile phone, first of all, as in the prior art, user name and password are used for identity authentication. Log in to Fetion.

[0061] Assuming that user A’s Fetion friend B has logged in to Fetion using a computer, after user A establishes a secure credit channel with Fetion friend B, user A receives friend B’s network card hardware address, and merges the network card hardware address with user A’s mobile phone IMEI number , using DES to generate a key; wherein, user A sends his mobile phone IMEI number to friend B, and friend B also uses the agreed DES to generate a key.

[0062] When conducting a secure trusted session with friend B, user A's client uses the generated key to encrypt the conversation content sent to friend B, and uses the generated key to decrypt the encrypted conversation content sent by friend B . Therefore, it is possible to prevent the content of the secure trusted session betwee...

Embodiment 2

[0064] The application scenario of the second embodiment is similar to that of the first embodiment, that is, user A has successfully logged in to Fetion on the mobile phone, and user A's friend B of Fetion has also logged in to Fetion by using a computer.

[0065] Assuming that user A and Fetion friend B are secure trusted friends, that is, a secure credit channel has been established. Before user A initiates a secure trusted session with Fetion friend B, user A's client requires user A to verify, and the security The trusted password is compared with the preset secure trusted password stored in user A's mobile phone. If they are consistent, the verification is passed, and user A is allowed to conduct a secure trusted session with Fetion friend B. Therefore, the account hacking phenomenon can be prevented, and the security problem of instant messaging is effectively solved. In addition, the preset security authorization password can be set to be dynamic, which further increas...
