Embodiment
The present invention provides intelligent unlocking method and the system of a kind of mobile terminal, and for making the object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below. It is to be understood that specific embodiment described herein is only in order to explain the present invention, it is not intended to limit the present invention.
As shown in Figure 1, the present invention provides a kind of intelligent unlocking method of mobile terminal, and it comprises the following steps:
S100, in advance by RSA Dynamic building algorithm pair of secret keys: PKI and private key; And PKI is saved in NFC device, private key is saved in mobile terminal;
S200, mobile terminal are connected by NFC communication agreement and NFC device, and obtain the PKI in NFC device, and prestore private key in the terminal and mate;
S300, the match is successful then mobile terminal is carried out RSA key authorization, generates unlocking screen instruction, is unlocked by the screen of mobile terminal.
The embodiment of the present invention unlocks by the unlocking manner of mobile terminal is set to NFC, and adopt RSA Dynamic building algorithm pair of secret keys to be stored in mobile terminal and the NFC device that connects with it respectively, by mobile terminal and NFC device are encrypted pairing, make to match after successfully with the private key in mobile terminal at the PKI of NFC device near mobile terminal and in NFC device, it is achieved the object of quick release.
First the NFC communication agreement in the present invention and RSA algorithm are explained. NFC communication agreement full name is NearFieldCommunication, is a kind of short radiotelegraphy apart from high frequency, under 13.56MHz frequency, effectively runs in 20 cm distance. The present invention is just based on NFC technique, it is achieved the automatic unblock of mobile terminal. It should be appreciated that, the present invention adopt NFC technique, do not adopt above-mentioned standard, NFC can be defined, such as the distance of reaction of NFC, namely mobile terminal with
NFC device is in the distance of setting can connect, and the distance of described setting is 1m, 0.5m, 0.3m or direct contact etc. And RSA algorithm is first algorithm that can be used for that data encryption also can be used for digital signature, the name of this algorithm is with the naming of inventor: RonRivest, AdiShamir and LeonardAdleman. Adopt RSA algorithm to realize data encryption to dynamically generate pair of secret keys in the present invention, make so only could realize unlocking when key pair success, substantially increase the security of mobile terminal.
In the step s 100, in advance by RSA Dynamic building algorithm pair of secret keys: PKI and private key; And PKI is saved in NFC device, private key is saved in mobile terminal, is kept in the client terminal of NFC device by PKI, and private key is kept in the service end of mobile terminal. Adopting RSA to carry out Encrypt and Decrypt mode in the present invention is encrypted private key, public key verifications. It should be noted that, a NCF equipment is to there being a PKI, but can being provided with multiple stage NFC device to be decrypted by mobile terminal, therefore can generate a key and multiple PKI, we just can select one or mobile terminal is unlocked by multiple stage NFC device like this. In addition, it is also possible to regenerate new pair of secret keys over time, even if being found PKI by others like this and also having unlocked without the need to worrying that mobile terminal is stolen.
And in step s 200, because the unlocking manner of mobile terminal is set to NFC and unlocks, therefore it can be connected by NFC communication agreement and NFC device, and obtains the PKI in NFC device, and prestore private key in the terminal and mate. Certainly, the inside of mobile terminal described in the present invention need to be provided with NFC module and could realize the technical program, it may be preferred that described mobile terminal refers to that smart mobile phone, IPAD etc. have the intelligent equipment of NFC module.
Below the specific operation process of described step S200 is described below: S201, in advance the unlocking manner of mobile terminal is set to NFC and unlocks, and is connected by NFC communication agreement and NFC device; S202, judge whether mobile terminal exists private key; When being, then enter step S203, when no, then regenerate private key, and be saved in mobile terminal; S203, mobile terminal obtain the PKI in the NFC device that connects, and with prestore private key in the terminal and mate.
Entering step S300 subsequently, after namely when the PKI in NFC device and the private key in mobile terminal, the match is successful, NFC device-mobile terminal is carried out RSA key authorization, generates unlocking screen instruction, is unlocked by the screen of mobile terminal.
In better embodiment, the present invention also comprises the following steps: S400, mate unsuccessful, exits unlock interface or returns to manual unlocking interface. It should be noted that, intelligent unlocking method of the present invention can with other unlocking screen programs with the use of, such as can with the labyrinth unblock in manual unlocking, unlock password etc. with the use of, like this, even if user because of certain reason NFC device cannot be used to carry out unlocking when, also other unlocking manner can be adopted to be unlocked by screen, do not affect the use to mobile terminal.
In better embodiment, the present invention also comprises the following steps: S500, again by RSA Dynamic building algorithm one to new key: PKI and private key; And again PKI is saved in NFC device, private key is saved in mobile terminal. Namely unlocks successfully every time or unsuccessful after, all can regenerate new pair of secret keys, can effectively improve the security of mobile terminal unblock like this.
Specifically, NFC device described in the embodiment of the present invention is Wearable NFC device, comprises any one in intelligent watch, Intelligent bracelet and intelligent glasses, and described intelligent glasses can be Google's glasses. Such as, the present invention adopts intelligent watch as NFC device, when mobile terminal is unlocked by needs, then only intelligent watch near mobile terminal or need to be touched mobile terminal gently, and by the key pair of its inside, realizing unlocking object, its method is simple and easy to realize, and has extremely high convenience.
In addition, as shown in Figure 3, the present invention also provides the intelligent unlocking system of a kind of mobile terminal, and wherein said intelligent unlocking system comprises:
Set module 100 in advance, in advance by RSA Dynamic building algorithm pair of secret keys: PKI and private key; And PKI is saved in NFC device, private key is saved in mobile terminal;
