Abstract

The embodiment of the invention discloses an information encryption and decryption method in a short message. The method comprises the following steps: a mobile terminal bottom layer receives at leastone original short message containing privacy information; when the original short message satisfies an encryption condition, the mobile terminal bottom layer encrypts the privacy information in theoriginal short message to generate an encrypted short message, and sends the encrypted short message to a short message application of a mobile terminal; and the short message application of the mobile terminal decrypts the encrypted short message after receiving the encrypted short message. The embodiment of the invention further discloses an information encryption and decryption apparatus in theshort message.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for encrypting and decrypting information in short messages. Background technique [0002] With the increasing popularity of mobile terminals, such as mobile phones, tablet computers, smart watches, etc., mobile terminals have become the most commonly used portable mobile electronic devices in people's lives. As a basic communication service in mobile terminals, the SMS function has long been It has become one of the necessary functions of the mobile terminal. And as various third-party applications emerge in endlessly in mobile terminals, many third-party applications have applied for permission to read short messages. Some malicious third-party applications may obtain the user's personal privacy by stealing the user's short message, threatening the user's information security. In order to avoid leakage of user information, mobile terminal SMS encryp...
