Problems solved by technology
[0004] Smart TVs are resource-constrained devices, and the data generated by the controls and their operations has always occupied the storage area of the body, which may cause some TVs to be unable to use the TV payment function due to limited storage space, and may also affect the user's experience with other applications, and The control file and its running data occupy the user space in the body storage, which is readable and writable for other applications and users, and is vulnerable to data leakage, tampering and other attacks, and the security is relatively poor

The invention discloses a control download method and system and a download guide module, and relates to the field of smart TV payment. The present invention divides control-related information into variable information and immutable information. The immutable information includes the download guide module and the public key of the control. The immutable information is stored in the read-only storage area of the TV to ensure the guidance control content and authentication content of the control. Not tampered with, so as to ensure the safety of the control download and call entry. The variable information includes the control and the data generated by the operation of the control. The variable information is stored in the RAM of the TV. Using the characteristics of data loss after the RAM is powered off, every time the TV is powered off The control and its operating data can be cleared after the TV is turned off, reducing the risk of data leakage and tampering, and reducing the storage space occupied by the control. The storage space is only temporarily occupied when the TV payment function is needed, and the storage space can be released in time after the TV is powered off. At the same time , the authenticity of the download source and the integrity of the control can be verified by using the public key of the control.
Description
technical field [0001] The invention relates to the field of smart TV payment, in particular to a control download method and system and a download guide module. Background technique [0002] With the development of triple play technology, many smart TVs have begun to have payment functions. For example, users can purchase value-added services such as consultation and video-on-demand through TV, and can also purchase physical goods on the TV mall. Before using the TV payment function, it is often necessary to download related controls. [0003] At present, after the TV downloads the installation package of the control, it stores the installation package of the control in RAM (Random Access Memory, random access memory), and then executes the installation process of the installation package of the control, and the control file formed after installation is stored in the fuselage such as the Flash chip In the user space in the storage, the data generated by the operation of t...
