Abstract
The present invention discloses a short message transmitting method, which comprises the steps of receiving the content of a short message and obtaining a pre-specified authority credential; encrypting the content of the short message; adding the pre-specified authority credential in the encrypted content of the short message according to the preset format of the short message content; and sending the short message to an short message receiving terminal. The short message receiving terminal judges whether the status value of a current network is consistent with the pre-specified authority credential contained in the short message or not. When the status value of the current network is judged to be consistent with the pre-specified authority credential contained in the short message, the content of the short massage is decrypted and displayed. According to the embodiments of the invention, a short message reading place is ensured to be within the expected range of a short message sender. In this way, the short massage carried by a short message receiver is prevented from being spread or even stolen out of the expected range, so that the security of the short message is improved. The invention also discloses a short message transmitting device, a short message receiving method and a short message receiving device.
