M2M (Machine-to-Machine) terminal security access method and terminal and management platform

Abstract

The invention relates to an M2M (Machine-to-Machine) terminal security access method. The method comprises the following steps that: the M2M terminal generates login request information including a first random number and encrypts the login request information by using a base password calculated according to security data pre-stored in a UIM (User Identifier Module); the M2M terminal calculates a ciphertext and the base password by using a digest algorithm so as to obtain a first digest; the M2M terminal transmits the ciphertext and the first digest to the M2M management platform; the M2M management platform adopts the digest algorithm to calculate and obtain a second digest; the first digest is compared with the second digest, if the first digest is the same as the second digest, the ciphertext is decrypted according to the base password, thereby obtaining the login request information and accomplishing the login; and the M2M terminal and the M2M management platform adopt the digest algorithm to calculate the security data and the first random number, respectively, thereby obtaining a session password and decrypting a subsequent session process by using the session password. The invention further relates to an M2M terminal and a management platform. According to the invention, a relatively perfect application security mechanism is provided for communication between the M2M terminal and the M2M management platform.

Description

technical field [0001] The present invention relates to a machine-to-machine communication (M2M for short) technology, and in particular to a secure access method for an M2M terminal, a terminal, and a management platform. Background technique [0002] In a broad sense, M2M includes the information interaction between machines and machines, mobile networks and machines, and people and machines, and is the main application form of the Internet of Things at this stage. M2M application is a service that takes M2M terminals as the core, establishes an information exchange link between M2M terminals, M2M management platform and M2M application platform, and completes functions such as terminal access and control, information collection and analysis. [0003] With the rapid development of M2M applications, the number of M2M terminals accessing the CDMA network is increasing, and the security issues of data transmission of M2M terminals are becoming increasingly prominent.

AI Technical Summary

Problems solved by technology

[0004] The M2M terminal and the M2M management platform use the application layer protocol to communicate on the data channel. Although the CDMA network based on the code division multiple access coding technology itself has certain security, most terminals currently do not provide a security mechanism and transmit business data in plain text. , a small number of terminals use SMS channels to send passwords to encrypt data, but there is still a lack of perfect application layer security mechanisms
