Abstract

A method and device for encrypting and decrypting information in a short message. The method comprises: a lower layer of a mobile terminal receives at least one original short message comprising private information; when the original short message satisfies an encryption criterion, the lower layer of the mobile terminal encrypts the private information in the original short message to generate an encrypted short message, transmits to a short message application of the mobile terminal the encrypted short message; and upon receiving the encrypted short message, the short message application of the mobile terminal decrypts the encrypted short 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...
