The invention discloses a kind of encrypted transmission methods of wearable device.Transmitting terminal acquires somatic data by biological information of human body monitoring device.After the completion of acquisition, receiving end will carry out matching connection with transmitting terminal.Receiving end sends a string of plaintext synchrodata frames to transmitting terminal at this time, after transmitting terminal receives clear data, it will timestamp is made seed key, calculated result is obtained using SHA1 Encryption Algorithm and returns to ACK to receiving end.Receiving end is calculated with SHA1 Encryption Algorithm, and sends the result to transmitting terminal.The calculated result received is compared transmitting terminal with itself seed key, judges whether to authenticate successfully.After authenticating successfully, carry out data transmission, transmitting terminal all carries out data encryption to the data transmitted with the cipher mode of AES128 encryption standard, guarantees the safety of data transmission.Receiving end equally carries out data receiver with the manner of decryption of AES128 encryption standard.By the above-mentioned means, the present invention can guarantee data transmission security, the leakage of user information is taken precautions against, is capable of the information security of effective guarantee user.
Description
Technical field
The present invention relates to the technical field of data transmission of wearable device, in particular to a kind of Data Encryption Transmission
Method.
Background technique
The main mode to be used of wireless communication has at present: WLAN (wireless fidelity), broader bandwidth but
Power consumption is higher；Infrared data transmission technology (Infrared Data Association, IrDA), although there is faster transmission speed
Rate, lower power consumption, but its transmission range is shorter, and between two device locations communicated using the technology
It must be aligned, centre cannot have obstacle；ZigBee technology low rate, low-power consumption, low cost and short distance, but cannot directly with
Android terminal interacts；Ultra wide band (Ultra WideBand, UWB) technology, although its transmission rate is high, its biography
Defeated distance is shorter and power consumption is higher；Bluetooth low energy consumption (Bluetooth Low Energy, BLE) is low in energy consumption, connection is quick, can
It is strong by property, transmission range is long.
Therefore Bluetooth transmission is widely used.Existing Bluetooth data transfer is unencryption.Do not add largely
The Bluetooth communication equipment of close certification and encrypted data transmission is easily cracked, if wearable medical monitoring equipment uses unencryption
Bluetooth communication, be likely to result in the leakage of data, cannot be ensured even with the life security of person.
Summary of the invention
Present invention seek to address that the above problem of the prior art.The present invention provides a kind of encrypted transmission side of wearable device
Method, it is intended to which the leakage of user information is taken precautions against in the safety of lifting means, ensures the information security of user.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows:
Step 1: transmitting terminal acquires somatic data by biological information of human body monitoring device.After the completion of acquisition, receiving end will
Matching connection is carried out with transmitting terminal.After receiving end is connect with transmitting terminal, receiving end is to a string of transmission synchronous clear data frames, data
Contained in frame timestamp, synchronic command, verification and.
Step 2: after transmitting terminal receives synchronous clear data frame, timestamp is close as the seed of SHA1 encryption identifying algorithm
Key.
Step 3: after receiving end receives the ack msg frame of transmitting terminal, then sending a frame authentication data frame.
Step 4: transmitting terminal will receive authentication data frame, carry out SHA1 with the timestamp of own cache is made seed key
The calculated result of Encryption Algorithm compares, if result is identical, certification passes through, otherwise the ack msg frame that return authentication passes through is recognized
Card failure, disconnects bluetooth connection.
Step 5: transmitting terminal and receiving end cryptographically carry out data communication.The data that cryptographically carry out are led to
News, including transmitting terminal to transmitting after the data encryption transmitted, the data received are decrypted in receiving end.
Specifically, in step 2, after transmitting terminal receives synchronous clear data frame, data accepted frame is returned to receiving end
Ack msg frame, and the timestamp in synchronous clear data frame is proposed, it caches close as the seed of SHA1 encryption identifying algorithm
Key.Data encryption is handled using the cipher mode of AES128 standard, and data deciphering uses the manner of decryption of AES128 standard
It is handled.
Further, authentication data frame described in step 3 is the data result calculated through SHA1 Hash Encryption Algorithm.
After the encrypted post-processing of data that bluetooth is sent, it can guarantee the safety of bluetooth equipment transmission data, take precautions against user
The information security of effective guarantee user is capable of in the leakage of information.
This method completes verification process using bluetooth connection, and the energy consumption that can play the role of transmission process is few, low delay.
This method can guarantee the real-time and accuracy of transmission process using timestamp as seed key.
Detailed description of the invention
Fig. 1 is the flow diagram of invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, detailed
Carefully describe.Described embodiment is only a part of the embodiments of the present invention.
Referring to Fig. 1, the method for the present invention includes the following steps:
Step 1: transmitting terminal (wearable device) acquires somatic data by biological information of human body monitoring device.Acquisition is completed
Afterwards, receiving end will carry out matching connection with transmitting terminal.After receiving end is connect with transmitting terminal, receiving end synchronizes in plain text to a string of transmission
Data frame, contain in data frame timestamp, synchronic command, verification and.
Step 2: transmitting terminal is received with step number in plain text according to frame, returns to ACK to receiving end, and timestamp is proposed, caching is made
For the seed key for encrypting identifying algorithm.
Step 3: receiving end receives ACK, sends the data encryption that a frame is calculated through SHA1 Hash Encryption Algorithm to transmitting terminal
As a result authentication data frame.
Step 4: transmitting terminal receives authentication data frame, carries out SHA1 Encryption Algorithm calculated result ratio with the seed key of itself
Right, if result is identical, certification passes through, the ack msg frame that return authentication passes through, otherwise authentification failure, disconnects bluetooth connection.
Step 5: receiving end receives the successful ack msg frame of certification, starts data transmission.
Step 6: transmitting terminal encrypts the data of acquisition with the cipher mode of AES128 encryption standard.
Step 7: encrypted data is sent to receiving end by transmitting terminal.
Step 8: the encryption data received is decrypted with the manner of decryption of AES128 encryption standard for receiving end.
Step 9: converting figure in android terminal for the data of decryption and show.
