Method and device for protecting short message security

Abstract

The invention discloses a Method and device for protecting short message security. The method comprises following steps: when detecting a short message sending operation on a mobile terminal, judging whether a secure short message function is started; if the function is started, encrypting the short message data according to an encryption and decryption algorithm in an appointed storage module; sending the short message data to an opposite party through a mobile phone network; decrypting the opposite party short message data according to the encryption and decryption algorithm in the appointed storage module, wherein the opposite party short message data are received through the mobile phone network; in this way, the transmitted short message data in the short message process are encrypted; the security of the short message contents is ensured; and the confidentiality demands of enterprises can be satisfied.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for protecting short message security. Background technique [0002] With the maturity and popularity of mobile terminals, personal mobile terminals represented by mobile phones and tablet computers have gradually entered the enterprise field. This phenomenon is called Bring Your Own Device (BYOD). Compared with the traditional informatization model, there are three major security risks in the BYOD environment: first, it is connected through a mobile network link, which is naturally in an open network, while traditional important information systems are connected through the enterprise intranet. secondly, the usage environment is different from the traditional informatization model, most of the traditional time is in a fixed office, and the possibility of device loss is very small, while BYOD usually uses mobile terminals, which are more likely to be lost; ...

Compared with the traditional informatization model, there are three major security risks in the BYOD environment: first, it is connected through a mobile network link, which is naturally in an open network, while traditional important information systems are connected through the enterprise intranet. secondly, the usage environment is different from the traditional informatization model, most of the traditional time is in a fixed office, and the possibility of device loss is very small, while BYOD usually uses mobile terminals, which are more likely to be lost; thirdly, BYOD uses Many personal APPs are often installed on personal devices at the same time, and there are a lot of malware in the personal APP market, which puts corporate data at risk of security

[0003] Therefore, in the process of enterprise employees using mobile terminals to send text messages, text messages may be intercepted and leaked.
