The invention discloses a safety enhancing method of Android intelligent television sensitive data and relates to further enhancement for safety of enhancing method of Android intelligent television sensitive data. Based on the prior art, a new strategy is provided so as to ensuring confidentiality of sensitive data more fundamentally. The method comprises steps of encrypting a virtual file system by use of a secret key system related to sole information of hardware and tightly binding the decryption secret key and a device, wherein if an attacker tries to transplant files and APK files storing sensitive data to other devices for execution, the attacker will not obtain the correct decryption secret key; and adding port calling authorization, wherein if the attacker tries to decompile a Java-layer coder, and recall encrypted a local JNI port of the virtual file system in local, port calling authorization errors will occur, and the attacker will fail to call the port and steal the sensitive data.
Description
technical field [0001] The invention relates to the further enhancement of the security of sensitive data of an Android smart TV. On the basis of the prior art, a new strategy is proposed to more fully ensure the confidentiality of the sensitive data, which belongs to the technical field of information security. Background technique [0002] At present, the smart TV industry is relatively closed compared with the smart phone industry. With the development of technologies such as triple play and multi-frequency interaction, attack forms will continue to increase. For some sensitive data, such as keys and user information, the confidentiality of data needs to be fully protected. The existence of malicious applications in Android smart TVs may make these sensitive data stolen, disseminated, and tampered with anytime and anywhere. In order to solve this kind of problem, an effective way is to design and realize the technology of safe storage area. The technology of said safe sto...
