Problems solved by technology

In the process of converting random numbers into instructions, the following two methods are usually used in the prior art: first, the random numbers are encrypted through the existing encryption algorithm, but the processing result of this type of algorithm is no extended number The number of bytes, each byte represents a kind of instruction, because there is no extended number, the number of instructions determined by this method is very small, and the number of determined instructions depends on the size of the random number itself; second, encrypt the random number Finally, the number of bytes with extended numbers is obtained, but the expanded data is encrypted, and each byte represents an instruction. This method causes multiple different bytes to represent the same instruction, and the repetition rate is large. Encryption bad sex

Abstract

Embodiments of the invention disclose an instruction determination method, apparatus and system, a device control method, apparatus and system, a device and a storage medium. The instruction determination method comprises the steps of encrypting a random number provided by a local device by applying a set encryption algorithm to determine encrypted data; converting each byte of the encrypted datainto a corresponding decimal number; splicing the decimal numbers to determine a target character string; splitting the target character string to determine sub target character strings; and determining corresponding relationships between the sub target character strings and a control instruction of the local device. The data after encryption of the random number is subjected to secondary encryption, so that the encrypted data is more intricate and complex; and when the instruction is determined according to the encrypted data, the repetitive rate is low and the encryption performance is good.

Description

technical field [0001] The invention relates to data transmission security technology, in particular to an instruction determination method, a device control method, a device, a system, a device and a storage medium. Background technique [0002] As people pay more attention to information security, there are more and more password protection methods. Most of the general password protection methods are limited to encryption using a certain encryption algorithm. This method only relies on the encryption algorithm itself for password protection. ensure. [0003] In the application scenario of smart device interaction, in order to improve the security of the interaction, random numbers are usually used for encryption, and the encrypted data is used as the password for the interaction between smart devices. The use of random numbers provides dynamic factors. [0004] During the process of realizing the present invention, the inventors found at least the following problems in th...
