Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The invention provides a method for storing encrypted data.

[0041] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the encrypted data storage method of the present invention.

[0042] In the first embodiment, the encrypted data storage method includes:

[0043] Step S10, receiving the original analog signal, and calculating and generating a preset number of limit random numbers according to the original analog signal;

[0044] In this embodiment, the terminal receives the original analog signal. The original analog signal can be a natural analog signal generated by an electric field, a magnetic field, etc. in nature, or an original analog signal sent by a signal source without filtering or other processing. , the analog signal has natural chaos and randomness, even the ...

Abstract

The invention discloses an encrypted data storage method. The method comprises the following steps of receiving an original simulation signal and making a calculation according to the original simulation signal to generate a preset number of limiting value random numbers; according to the preset number of the limiting value random numbers, obtaining a corresponding preset number of storage addresses in a terminal and generating a storage address mapping table; and partitioning encrypted data required to be stored into a preset number of encrypted data partitions according to a preset number of partitions and correspondingly storing the encrypted data partitions into the preset number of the storage addresses based on the storage address mapping table. The invention furthermore discloses an encrypted data storage terminal. According to the method and terminal, the security of encrypted data storage is greatly improved.

Description

technical field [0001] The present invention relates to the field of television technology, in particular to a method for storing encrypted data and a terminal. Background technique [0002] With the continuous development of smart terminals such as TVs, smart terminals have allowed users to freely install required software, use browsers to browse the Internet, and use cloud services. These application scenarios require smart terminals to provide A variety of access and control interfaces make the data input and output of smart terminals very rich and complex, and the existence of external access and control interfaces makes it possible for smart terminals to be accessed and attacked maliciously, especially as more and more Many users use online banking and software with personal privacy functions on smart terminals. In this way, encrypted data related to user information will be generated on smart terminals, and encrypted data must be stored securely on smart terminals to p...
