Embodiment Construction

[0029] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0030] Using the identity authentication method of the embodiment of the present invention, the user login process is as follows: figure 1 . The client generates a set of random key pairs, and sends the public key to the server via Bluetooth, and at the same time initiates a login application to the server. After the server receives it, it switches to the login connection mode. The client then encrypts the ID saved during registration with the public key of the server through ECC, digitally signs it with its own private key, and sends it to the server, relying on this ID as identity information. The server side decrypts the plaintext and checks the signature to confirm that the information is indeed sent by a legitimate user, and checks the decrypted plaintext according to the user ID saved by itself, and the authorization operation can only be perf...

Abstract

The invention provides an internet-of-things identity authentication method based on Bluetooth communication access, and relates to an identity authentication method of internet-of-things communication. The internet-of-things identity authentication method comprises the following steps of generating a dynamic secret key pair by using a user side; performing public key exchange between the user side and a server side; registering by using the user side according to registration codes; generating an unique user side identity (ID) authentication with permissions by using the server side; encrypting and digitally signing a user ID (identity) by using the server side; transmitting the user ID to the server side; storing the ID of the server side after the server side decrypts and verifies the digital signature of the user ID; dynamically generating a new secret key pair by using the user side; encrypting and digitally signing the identity (ID) authentication of the user side; transmitting the identity authentication to the server side to perform login authentication; decrypting and verifying the digital signature of information transmitted by the user side by using the server side; identifying the legality of identity of a user; and stipulating permission of the user according to permission grade of the identity (ID) authentication of the user. Registering or login connection can be carried out conveniently in a Bluetooth coverage region. Only a public key and encrypted data are transmitted in a communication process, and data transmission safety is guaranteed.

Description

technical field [0001] The invention relates to an identity authentication method for Internet of Things communication, in particular to an identity authentication method for Internet of Things based on Bluetooth communication access. Background technique [0002] With the rapid development of electronic communication devices in the Internet of Things era, people's lives are increasingly dependent on the convenience brought by electronic devices, and the daily privacy that is closely related to people has become various data stored in electronic devices. Therefore, information security is getting better and better. has increasingly become the focus of attention. Identity authentication, as a means of verifying the legitimacy of a communication entity, can effectively prevent third parties from masquerading to achieve unauthorized communication purposes and protect user privacy and security to a certain extent. [0003] Many authentication methods in China today use the simp...
