Problems solved by technology

[0004] Using the above-mentioned first encryption method, there is a risk that the numbers of some types of operators cannot be read or after the smartphone changes the mobile phone number (such as changing the SIM card), the risk of encryption failure; using the above-mentioned second encryption method, although the Andriod device application Encrypted by the device serial number, but the Andriod application is easy to be cracked, and once the Andriod application is cracked, the code of the application is completely open, and the encryption method is easily exposed

Embodiment 1

[0023] Embodiment 1. A file encryption method based on Andriod device authentication. Combine below figure 1 with figure 2 The method provided by the present invention is described in detail.

[0024] figure 1 Among them, S101, at the bottom layer of the Andriod operating system, obtain the unique identification code of the Andriod device.

[0025] Specifically, this embodiment is mainly applicable to the Andriod operating system. First, the unique identification code of the Andriod device is obtained at the bottom layer of the Andriod operating system, and the unique identification code of the Andriod device cannot be changed. Wherein, the Andriod device unique identification code has multiple manifestations, can be Andriod device serial number (serial number), also can be the physical address of Andriod device (such as MAC, Media Access Control Address, media access control address, or claim Andriod address ).

Abstract

The invention discloses a file encryption method and device based on Andriod equipment authentication. The method comprises the following steps: obtaining an unique Andriod equipment identification code on a bottom layer of an Andriod operating system; encrypting the obtained unique Andriod equipment identification code and generating an encrypted file; judging whether the encrypted file is the same as a preset external encrypted file, wherein if the encrypted file is the same as the preset external encrypted file, the validation is successful, and otherwise, the validation fails; transmitting successful validation information or failed validation information to an application layer of the Andriod operating system through a data transfer layer of the Andriod operating system; enabling the application layer to determine to allow or deny the access to an application process according to the received successful validation information or the received failed validation information.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a file encryption method and device based on Andriod device authentication. Background technique [0002] With the development of communication technology, the application of Andriod devices, especially smart mobile devices, is becoming more and more popular. At the same time, due to the existence of various hackers, the security of smart mobile devices has attracted more and more attention from users. [0003] For current Andriod devices, taking smart phones as an example, there are usually two encryption methods: the first is to encrypt by reading the mobile phone number; the second is to encrypt at the application layer based on the serial number of the Andriod device Way. [0004] Using the above-mentioned first encryption method, there is a risk that the numbers of some types of operators cannot be read or after the smart phone changes the mobile phone number (...
