Terminal legality verifying method and device

Abstract

The invention discloses a terminal legality verifying method and device. The method comprises the following steps of obtaining a signature, a hardware equipment identification and a random number which are burned on specific locations of a terminal in advance; according to a preset deciphering rule, the signature is decrypted so as to obtain corresponding plaintext information; the hardware equipment identification and the random number are spliced to obtain a splicing character string; the plaintext information is matched with the splicing character string; if the plaintext information is not matched with the splicing character string, it is judged that the terminal is not legal; if the plaintext information is matched with the splicing character string, it is judged that the terminal is legal. By means of the method, the safety of the terminal to access a server is improved, it is ensured that all terminals accessing the server are legal, and the verifying effect of the safety is improved.

Description

technical field [0001] The present invention relates to the technical field of network security, in particular to a method and device for checking terminal legitimacy. Background technique [0002] With the rapid development of the Internet and smart homes, more and more users access the server through the terminal to achieve various functions. purpose of household appliances. When accessing the server of the application program through the terminal to control the household appliances, it is necessary to check the legitimacy of the terminal through the verification server. However, during the process of verifying the terminal, the verification server may be maliciously accessed by illegal users, causing legitimate users to be unable to normally access the application server to control household appliances, and even lead to leakage of private information of legitimate users. [0003] In related technologies, the authentication server usually uses the following methods to ve...

Problems solved by technology

[0004] However, there are problems: the set key and password are generally fixed, and as long as they interact, they may be intercepted and cracked, which may easily lead to key leakage; the method of verifying based on user identity or password also has the risk of being stolen , resulting in poor security verification, and cannot effectively solve the problem of malicious users forging legal identities to access the application server to control household appliances
