Abstract

A method for improving the security of data transmission includes: generating a random number, and obtaining a key timestamp for generating the random number; calculating summary information of the random number through a digest algorithm, and generating an An asymmetric key pair of a private key and a public key corresponding to the time stamp; verify the user identity information through the key time stamp and the private key; when the user identity information is verified, select the part of the private key The bytes generate a symmetric key, and the data is encrypted for transmission by the symmetric key. Encrypting random numbers through abstract information is beneficial to improve the difficulty of data cracking, and after user authentication through private key, a symmetric key is generated through a private key with high security for data transmission, which can effectively ensure the security of data transmission sex.

Description

technical field [0001] The present application belongs to the communication field, and in particular relates to an Internet of Things device and a method and device for improving data transmission security. Background technique [0002] With the development of communication technology, more and more IoT devices have entered people's lives, bringing great convenience to people's work and life. With the rapid development of the Internet of Things, the promotion of IPV6 communication protocol and 5G communication, the speed of network transmission and response is getting faster and faster, and the security and reliability requirements of the Internet of Things are getting higher and higher. [0003] In the traditional Internet of Things industry, a large number of Internet of Things devices are too one-sidedly pursuing emerging services and functions, and it is difficult to protect the devices themselves or ignore the security of the devices, coupled with immature protection so...
