The invention discloses a short message processing method, device and system. The method comprises the steps of carrying out PDU coding on a received short message, generating a PDU data packet and encrypting a digest sequence of a preset length to obtain a digital signature, wherein the digest sequence is calculated according to the PDU data packet; and adding the digital signature to the PDU data packet and sending the PDU data packet to a receiving terminal, thereby enabling the receiving terminal to determine whether the received short message comes from a legal base station or not according to the received PDU data packet comprising the digital signature. The method, the device and the system have the beneficial effects that a short message service center carries out digital signature processing on the received short message and sends the short message comprising the digital signature to the receiving terminal, and after receiving the short message comprising the digital signature, the receiving terminal extracts the digital signature and verifies the digital signature, so whether the short message comes from the legal base station or not is judged, an identification rate for the short message of an illegal base station can be improved, and the user security and user experience can be improved.
Description
technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a short message processing method, device and system. Background technique [0002] "Pseudo base station" is a fake base station, which is a high-tech instrument. It uses short message group senders and other related equipment to search for mobile phone card information centered on it and within a certain radius, and forcibly connects the user's mobile phone signal to the pseudo base station. Base stations, preventing users from connecting to public telecommunications networks. The fake base station pretends to be the base station of the operator, and arbitrarily uses other people's mobile phone numbers to forcibly send short messages such as fraud and advertising to the user's mobile phone, harassing the user and affecting the normal mobile phone use of the mobile phone user. Moreover, the pseudo-base station does not have the voice communication ...
