Problems solved by technology

However, at present, the broadcast mechanism of the operating system itself is not very safe, mainly in the following aspects: the broadcast identifier carried in the broadcast data sent by the broadcast sender to the same broadcast receiver each time is fixed, and the broadcast The data can be received by any application registered as a broadcast receiver on the system. When a malicious application receives the broadcast data, it can obtain the content and broadcast identifier of the broadcast data, and imitate the broadcast according to the broadcast identifier. Other broadcast data, and then fake control of the broadcast receiver
[0003] To sum up, for the existing technology, the transmission of broadcast data between the broadcast sender and the broadcast receiver in the operating system is not secure enough, and the broadcast receiver is easily controlled by malicious applications

Abstract

The invention discloses a broadcasting method and device which are used for improving security of broadcast contents and preventing a case that a broadcast receiver is controlled by a counterfeiter. The broadcast sending method provided by the invention comprises the steps that: when a broadcast sender needs to send broadcast data to the broadcast receiver, the broadcast sender executes a process of requesting the broadcast receiver for authentication; after determining that the process of requesting the broadcast receiver for authentication is executed successfully, the broadcast sender determines a receiving identifier for indicating the broadcast receiver to receive the broadcast data currently sent by the broadcast sender; and the broadcast sender sends the broadcast data to the broadcast receiver according to the receiving identifier.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a broadcasting method and device. Background technique [0002] In an existing operating system, multiple applications communicate by sending broadcasts. However, at present, the broadcast mechanism of the operating system itself is not very safe, mainly in the following aspects: the broadcast identifier carried in the broadcast data sent by the broadcast sender to the same broadcast receiver each time is fixed, and the broadcast The data can be received by any application registered as a broadcast receiver on the system. When a malicious application receives the broadcast data, it can obtain the content and broadcast identifier of the broadcast data, and imitate the broadcast according to the broadcast identifier. Other broadcast data, and then fake control of the broadcast receiver. [0003] To sum up, for the prior art, the transmission of broadcast data bet...
