Description
Technical field
The present invention relates to intelligent wireless terminal device access authentication field, a kind of nothing based on radio-frequency fingerprint is specifically related to
Line intelligent terminal access authentication method and system.
Background technology
With the fast development of development of Mobile Internet technology and making rapid progress for mobile terminal, smart mobile phone, tablet personal computer etc.
Various mobile terminals have been penetrated into daily life and work, are also had particularly in terms of emerging Internet of Things and cloud computing wide
Wealthy application prospect.But mobile intelligent terminal is because the limitation of cost makes its performance also limited, along with open mobile nothing
Gauze network there is also many risks, is subject to the invasion of hacker or disabled user and other attacks in itself, for example clone,
Reset, palm off, eavesdropping, distorting, Denial of Service attack etc..The authentication of communicating pair is information security and secret protection
Basis is with crucial, once identity authorization system is destroyed, system will can be sayed without safety.
Traditional Verification System is realized based on cryptographic system and security protocol, that is, communicating pair is according in advance
Shared secret information simultaneously verifies the legitimacy of identity each other by challenging with the interactive mode of response.Common authentication
Mode mainly includes:Static password authentication, one-time password authentication, the identity based on digital certificate and based on hardware device are recognized
Card.But also there is certain limitation their application scenario.Compared to traditional PC authentications, the body of mobile intelligent terminal
Part certification there is also some differences, such as：The calculating of mobile intelligent terminal and storage capacity are limited, and energy consumption is limited, are not suitable for adopting
With the AES of complexity, also need to avoid frequently number of communications etc..Therefore, it is necessary to designing one is applied to intelligent movable end
Hold the safe identity verification scheme of communication system.
In recent years, the non-cipher authentication technique according to physical layer information be proposed for the information security of wireless device with it is hidden
Private protection, this non-cipher authentication mode have the characteristics of higher security performance, low complex degree.Based on radio-frequency fingerprint (Radio
Frequency Fingerprints, RFF) radio transition equipment identification with checking be one of non-cipher authentication technique.Should
The radio signal for the carrying radio transition equipment hardware information that interface differential technique receives carries out waveform extracting and obtains RFF, RFF
Embody the unique trait of radio transition equipment hardware；The main reason for producing RFF is that the electronic component of transmitting set is deposited
In tolerance phenomenon.Even if component tolerance cause wireless device emitting portion structure and component nominal value all, its system
Property is also not exclusively the same；In radio frequency band, small component difference, which also results in radiofrequency signal, very big difference, so passing through
RFF, which carries out uniqueness identification to electronic equipment, has feasibility；And the certification based on RFF makes full use of the ardware feature of terminal,
With little need for extra calculating, there is low complexity.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of intelligent wireless terminal based on radio-frequency fingerprint
Access authentication method and system, it can realize and be mutually authenticated between intelligent wireless terminal and server, reduce intelligent wireless terminal
The complexity of authentication and the security for improving authentication.
The purpose of the present invention is achieved through the following technical solutions：A kind of intelligent wireless terminal based on radio-frequency fingerprint
Access authentication method, comprise the following steps：
S1. initialization registration typing：The log-in password of intelligent wireless terminal-pair user input is transferred to clothes after being encrypted
Business device, and registration request is initiated to server, server is complete according to the password after encryption and the radio-frequency fingerprint of intelligent wireless terminal
Typing is registered into initialization；Specifically, the step S1 includes following sub-step：S101. user inputs to intelligent wireless terminal
Password PW, the password of intelligent wireless terminal-pair input are encrypted, and obtain Crypted password CS=H (PW), wherein, H (PW) is represented
Calculating is encrypted using Hash function pairs input password PW；S102. Crypted password CS is transferred to service by intelligent wireless terminal
Device, and send registration request Reg to server；S103. server is from the registration request Reg received and Crypted password CS letter
The radio-frequency fingerprint RFF of intelligent wireless terminal is extracted in number waveform；S104. radio-frequency fingerprint RFF of the server to intelligent wireless terminal
Verified, judge whether user has been present：If user is not present, shared secret value K is generated, then will be encrypted close
Code CS, radio-frequency fingerprint RFF and shared secret value K are stored in database, and send shared secret value K to intelligent wireless terminal；
If user is present, the already present announcement information of user is fed back into intelligent wireless terminal, registration terminates；S105. intelligent wireless
After terminal receives shared secret value K, preserved, and confirmation message Ack is sent to server, registration is completed.
S2. login authentication is run：When user asks login service device, typing information is registered according to initialization, carried out wireless
Two-way legitimacy certification between intelligent terminal and server, and intelligent wireless terminal and server are managed according to authentication result
Session break-make.Specifically, the step S2 includes following sub-step：S201. when user asks login service device, wireless intelligence is passed through
Energy terminal input password PW, then generates login request message M1And server is sent to, the request message M1In comprising ID believe
Breath, id information initialization are defaulted as 0；S202. the legitimacy of server authentication intelligent wireless terminal, server is first from receiving
Signal waveform in extract intelligent wireless terminal radio-frequency fingerprint RFFc(M1), then judge radio-frequency fingerprint RFFc(M1) whether deposit
In database：If it does not exist, then disconnect server and the session of intelligent wireless terminal；If it does, into step S203；
S203. radio-frequency fingerprint RFF is searched in databasec(M1) corresponding to Crypted password CS, followed by pseudorandom occur algorithm generation
New random number PS (new), calculate and judge whether H (PS (new)) is equal to H (ID), wherein, H (PS (new)) represents random number
PS (new) Hash result of calculations, H (ID) represent the Hash result of calculations to ID：If H (PS (new)) is equal with H (ID),
New PS (new) is then regenerated, return to step S203 rejudges whether H (PS (new)) is equal to H (ID)；If H (PS
(new) it is) unequal with H (ID), then send checking message M to intelligent wireless terminal2, checking message M2In comprising Crypted password believe
