Description
Technical Field
The invention relates to the technical field of terminals, in particular to a short message tamper-proofing method and a short message tamper-proofing device.
Background
At present, aiming at the problem that a Short Message is at risk of being tampered during transmission, the existing tamper-resistant scheme for SMS (Short Message Service) content generally adopts a mode of information content digital signature, or encrypts received information content at a communication module of a terminal, and an application layer decrypts the received encrypted information content to obtain actually sent information content, specifically:
(I) Prior Art scheme I
Based on the mode of adopting the digital signature of the information content, when the short message is sent, the sent content is digitally signed, the receiving end verifies the digital signature of the received content, the received content is considered as the effective information content only if the digital signature is verified, otherwise, the received content is considered as the tampered information content;
(II) Prior Art scheme II
The received content is encrypted at the terminal communication module, the encrypted content is uploaded to the application layer through the communication module, and the application layer decrypts the encrypted content to obtain the correct short message content, so that the possibility that the short message content is tampered in the transmission process from the receiving module to the application layer is solved.
Although the technical scheme solves the problem that the information content is tampered in the process of receiving the short message by the terminal, the following defects still exist:
(I) the defects of the first technical scheme
Although the scheme can realize the function of preventing the information content from being tampered from the sending end to the receiving end, the size of the sent information content can be increased due to the adoption of the digital signature, the control requirement of the short message on the word number of the content is higher (if the short message is a long short message, the cost of sending the short message by a user can be increased), in addition, the mobile terminals used by the user are not necessarily of the same brand, and the protocols for encrypting and decrypting the digital signatures of the sending end and the receiving end can not be consistent, so that the decryption cannot be effectively carried out, and the mobile terminals cannot be widely used when a unified standard protocol does not exist;
(II) the defects of the second prior art scheme
Although the scheme solves the problem that the information content is tampered in the process of receiving the short message by the terminal, the content after receiving the data cannot be monitored in a tamper-proof manner, and particularly for most of the existing open terminals, malicious programs or viruses can tamper with the received data, so that a user can check wrong information.
