Identity authentication method and device for terminal device, terminal device and server

Abstract

The embodiment of the invention provides an identity authentication method and device for a terminal device, the terminal device and a server. The method comprises the steps of sending an identity authentication request to the server, wherein the request comprises a sequence number SN of the terminal device and a security sequence number SSN existing in the terminal device, and the security sequence number SSN has corresponding identification information; and receiving an identity authentication result returned by the server. The SSN can be effectively prevented from being broken by reverse engineering, the SSN is guaranteed to be safe and valid, and the security of the terminal device and system is improved.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to an identity authentication method for terminal equipment, an identity authentication device for terminal equipment, a terminal equipment and a server. Background technique [0002] With the development of technology, there are more and more smart terminals of all kinds, which bring great convenience to people's work and life. Through smart terminals, people can obtain information, make purchases, and complete payment. Therefore, the security of smart terminals has attracted more and more attention. [0003] Usually, any intelligent terminal will have a unique serial number SN (Serial Number) to identify the identity of the terminal. After the smart terminal accesses the network each time, it needs to send the serial number to the server, and the server will identify and verify the identity of the smart terminal according to the received serial number. However, the ...

Problems solved by technology

However, the serial number SN of most smart terminals is encoded in some kind of plaintext, such as a self-increasing integer sequence, which is extremely easy to be cracked by malicious programs and the identity of the device is falsely used. Once the identity of the smart terminal is fraudulently used, the It may lead to some malicious attacks and pose a serious threat to the security of terminal equipment

[0004] In the prior art, based on the RSA asymmetric encryption algorithm, a signature certificate can be issued for each smart terminal, and by using the signature certificate of the device to verify the identity of the device, the identity verification of the smart terminal can be completed in a safe environment, but , adopting the above scheme needs to establish its own independent CA (Certification Authority, certification) system, and the cost is relatively high
