用于撤回短消息的移动终端、服务器、系统及方法
摘要：
本发明提供一种用于撤回短消息的移动终端、服务器、系统及方法，该移动终端包括：处理模块，用于对需要发送的短消息进行加密处理，生成加密短消息，并创建所述加密短消息对应的加密密钥信息；第一发送模块，用于将所述加密短消息和所述加密密钥信息发送给服务器；存储模块，用于存储已发送的加密短消息的相关信息；撤回模块，用于根据所述已发送的加密短消息的相关信息生成撤回加密短消息的信息；第二发送模块，用于将所述撤回加密短消息的信息发送给所述服务器。本发明可通过取消服务器上存储的加密短消息对应的加密密钥信息，使接收方无法查看该加密短消息，以达到撤回短消息的目的。
摘要（英）：

The invention provides a mobile terminal for withdrawing the short message, a server, a system and a method for the same. The mobile terminal comprises: a processing module for performing encryption treatment for the short message to be sent, to generate an encrypted short message, and establishing an encrypted key message corresponding to the encrypted short message; a first sending module for sending the encrypted short message and the encrypted key message to a server; a storing module for storing information associated with the sent encrypted short message; a withdrawing module for generating information for withdrawing the encrypted short message according to the information associated with the sent encrypted short message; a second sending module for sending the information of the withdrawn encrypted short message to the server. The invention cancels the encrypted key information corresponding to the encrypted short message stored on the server, so that the receiver part cannot check the encrypted short message; therefore, the invention implements the purpose of withdrawing the short message.
