Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of identity identifying methods based on Internet of Things, device, end
End, server and medium.
Background technique
OneM2M internet of things field International Organization for standardization is found in 2011, is the Internet of Things communication protocol of current mainstream
One of, it has been widely used in the vertical applications such as smart city, intelligent medical, smart home, communications and transportation.Herein will below
Refer to application entity or user equipment with AE generation, refers to generic service entity with CSE generation, in oneM2M system, by application entity
(AE) request issued can be received by generic service entity (CSE), and CSE can agree to asking for AE after the identity that AE is completed in certification
It asks, is linked into system, and provide corresponding service for AE.Specifically, have in OneM2M system one it is simple
ID authentication mechanism, cardinal principle are that each receives connection request and the CSE for providing service for terminal is owned by one solely
Vertical username and password and URL, any AE for wanting to receive CSE service need to send specified lattice to the URL of target CSE
The data packet of formula, and in the data packet must the username and password with target CSE in order to user name whereby and close
Code completes the authentication of AE.The entitled admin password of the initial user of system is admin, and CSE can modify the user name of default
And password.
Since AE has been written into username and password in data packet in the form of plaintext, hacker is easy to intercepted data
Packet, then hacker is just easy to parse the user name of the inside target CSE, password and URL, subsequent hacker can disguise oneself as AE to
Request is sent in target CSE, and can complete authentication using the username and password intercepted and captured, and is successfully linked to CSE
In, all services in CSE are obtained, hacker's not only information all in available CSE, can also send false service at this time
Request, because the service ability of CSE is limited, if the false AE of hacker is allowed to obtain the service that a large amount of services are bound to cause real AE
Delay and obstruction.When hacker obtains the user name of CSE, pseudo- AE can be not only created after password and URL and occupies the public of CSE
Resource can also send a large amount of normal formats but include the data packet of error message, interfere normal communication process.
Therefore, existing ID authentication mechanism is simple and with plaintext transmission information, causes more serious safety problem.

The encrypted encrypted result of row；
Server-side verifies the encrypted result using the public key, and according to the conjunction of verification result Authentication Client
Method.
13 embodiments of the invention provide a kind of storage medium, and computer program is stored on the storage medium, described
The step of authentication based on Internet of Things as follows is realized when computer program is executed by processor:
Client sends digital certificate to server-side, carries public key in the digital certificate；
Client receives the verification information that server-side is sent, and is encrypted using private key to the verification information, and will
Encrypted result feeds back to server-side, so that server-side carries out verifying to the encrypted result using the public key and is tied according to verifying
The legitimacy of fruit Authentication Client.
Fourteenth embodiment of the invention provides a kind of identity authorization system based on Internet of Things, in conjunction with Fig. 9, including AE and
CSE,
AE is used to send a communication request to CSE；And oneself digital certificate is sent to CSE.It include one in certificate
Public key is used to encryption information, and private key is held by client；
After CSE receives the digital certificate of AE transmission, CSE verifies whether this digital certificate is AE, if digital certificate
Belong to AE, CSE then sends a random character string to AE；
AE encrypts character string using private key, and the result of encryption is returned to CSE；
CSE utilize obtained from digital certificate public key decryptions AE feedback encrypted result, if decrypted result with before
The random string of generation is consistent, then the identity of Authentication Client is correct；
After the identity of verifying AE is correct, CSE generates a symmetric encipherment algorithm and key, and using public key to Encryption Algorithm
It is encrypted with key, and encrypted result is sent to AE；
AE is received encrypted Encryption Algorithm and key and is decrypted using private key, to obtain Encryption Algorithm and key,
And it is communicated using Encryption Algorithm and key is obtained with CSE.
In the present embodiment CSE using public key it is close to Encryption Algorithm and key after be sent to AE, intercepted and captured even if by hacker
It not will cause safety problem, because only that holding the private key that can be decrypted in AE, the safety of authentication improved, finally, CSE
It can use symmetric encipherment algorithm with AE to encrypt and decrypt Content of Communication.
