Abstract
The invention discloses an intelligent terminal data encryption method and device and belongs to the technical field of communication. An external encryption device is utilized to encrypt data of an intelligent terminal to protect privacy data of a mobile phone. The mobile phone transmits the data or files to the encryption device through a bluetooth communication protocol, and the encryption device encrypts the data and feeds an encryption result back to the mobile phone. The encryption device comprises a bluetooth communication module, a data encryption module, a microcontroller, a TF card reader, an indicator light, a battery and a power switch.
Description
Technical field
The present invention relates to communication technical field, relate in particular to the method and apparatus that a kind of Intelligent terminal data is encrypted.
Background technology
Along with popularizing of the intelligent terminals such as mobile phone, mobile phone viruses, wooden horse software, fishing software occur in a large number, cause facing numerous security threats in intelligent terminal application, the safety practice adopting in intelligent terminal at present can not fine assurance internal data and the safety of communicating by letter, cannot meet some requirements to the higher department of security requirement and personnel such as government, enterprise, public security, commercial affairs, so the use of intelligent terminal is very limited.
Summary of the invention
(1) technical matters that will solve
For above-mentioned defect, the technical problem to be solved in the present invention is how to design a kind of method and apparatus of encrypting to Intelligent terminal data, and data or the file of secret in protection intelligent terminal, for intelligent terminal provides safe environment for use.
(2) technical scheme
For addressing the above problem, the invention provides a kind of data ciphering method to intelligent terminal, comprising:
S1, intelligent terminal and encryption device, by Bluetooth pairing, connect;
S2, encryption device needed the owner to input PIN code before encrypted work;
Data or file that S3, intelligent terminal are encrypted needs send to encryption device;
S4, encryption device carry out encrypting according to the cryptographic algorithm of agreement to data or file;
S5, encryption device are beamed back intelligent terminal by encrypted result.
Further, intelligent terminal can be realized data deciphering by encryption device and work, and decryption work completes the reverse operation of encrypted work, is used in conjunction with encrypted work.
Further, intelligent terminal comprises that smart mobile phone, panel computer and personal digital assistant (PDA) etc. have the mobile electronic device of Bluetooth function.
For addressing the above problem, the device that the present invention also provides a kind of Intelligent terminal data to encrypt, comprising: bluetooth communication, data encryption module, microcontroller, TF card reader, pilot lamp, battery and power switch.
Further, described data encryption module, is one of CPU card encryption module of SAM module or TF card form.The CPU card encryption module of TF card form is accessed by TF card reader.Data encryption module can provide the encryption methods such as digital signature, digital envelope, data encryption.
Further, described intelligent terminal encryption device, controls powered battery by power switch, and encryption device is by the color indicating operating status of pilot lamp.Pilot lamp provides four kinds of indicating status, redness: bluetooth is not matched; Yellow: bluetooth is matched, and PIN does not input; Green: bluetooth is matched, and PIN input is correct; Red flicker: bluetooth is matched, PIN input error.
(3) beneficial effect
The method and apparatus that a kind of Intelligent terminal data provided by the invention is encrypted, data or file that intelligent terminal is encrypted needs send to encryption device, obtain encrypt data, then encrypt data are stored or transmitted.The mode that can encrypt by Bluetooth encryption device, improves intelligent terminal such as the degree of safety of mobile phone.

In Fig. 2: 1-bluetooth communication, 2-data encryption module, 3-microcontroller, 4-TF card reader, 5-pilot lamp, 6-battery, 7-power switch
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Embodiment:
The method and apparatus that provides a kind of Intelligent terminal data to encrypt in the present embodiment, the present embodiment be take mobile phone and is described as example, and as shown in Figure 1, encryption device inner structure is as shown in Figure 2 for encrypting step.
First, after mobile phone and encryption device start, require both sides to carry out Bluetooth pairing, in pairing process, will on mobile phone, input the Bluetooth pairing password of encryption device, this Bluetooth pairing password is the password that encryption device inside sets in advance, to prevent the unauthorized access of other bluetooth cellular phones, after successful matching, pilot lamp becomes yellow from redness.
The second, mobile phone uses before encryption device is encrypted work, need to shift to an earlier date the password of input reference encryption device, i.e. PIN code, and encryption device obtains after correct PIN, and pilot lamp becomes green from yellow, and after this, encryption device is in serviceable condition.
The 3rd, data or file that mobile phone is encrypted needs send to encryption device by bluetooth.
The 4th, the microcontroller of encryption device inside utilizes the CPU card encryption module of data encryption module or TF card form, data or file are carried out to asymmetric encryption, according to the cryptographic algorithm of agreement, carry out, the encryption functions such as digital signature, digital envelope, authentication are provided.
The 5th, encryption device sends it back mobile phone by the encrypt data after encrypting, and by the application program of mobile phone, is entered encrypt data is stored or transmitted.
Method provided by the invention can make the private data of mobile phone be protected.When needs are encrypted or deciphered, open encryption device cell switch and operate; While not using, the cell switch of end encryption device.Mobile phone and encryption device are separately deposited, and encryption device plays the effect of hardware encipher, distinguish and conventional software cryptography mode, and the present invention is more reliable.Even if mobile phone or data in mobile phone are stolen, owing to there is no this hardware of encryption device, quite there is no key, stolen data also cannot be deciphered, so can effectively protect the data in mobile phone.Simultaneously the encryption device based on bluetooth is because volume is small and exquisite, very convenient portably using, similarly be mobile phone one secret key, by the owner of encryption device, grasp its entitlement and PIN code.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
