Abstract
The invention discloses an authentication and key agreement method between light-weight smart mobile phones. The method comprises the following steps of collecting data returned from a sensor, allowing a first intelligent terminal and a second intelligent terminal to operate according to a preset mode, collecting corresponding perception data returned from the sensor and generated for the operation, exchanging the collected data, allowing the first intelligent terminal and the second intelligent terminal to exchange partial perception data, verifying the exchanged data, allowing the intelligent terminals to compare and verify the received data and a corresponding part of the self-owned perception data, generating an agreement key, after passing verification, allowing the intelligent terminals to operate the perception data according to the preset mode, and taking a computed value as the agreement key. The method adopts simultaneous operation of the two intelligent terminals to generate the same sensor data as an authentication evidence and a key seed, and as the operation is random, the key is also random, the authentication is reliable, and the key is safe.
Description
Technical field
The present invention relates to the mobile message security fields, relate in particular to the Authentication and Key Agreement method and system between a kind of smart mobile phone of lightweight.
?
Background technology
Closely may need mutual transmission of information in the situation between two smart mobile phones, but, how before transmission of information, mutually to consult a key and be used for encrypting the information of transmitting, and before transmission of information, recipient or transmit leg are authenticated, to get rid of potential hostile recipient and to forge transmit leg, so before radio communication is set up, need to carry out Authentication and Key Agreement.Authentication be sure of that communication counterpart is legal.Key agreement is for the encryption key of setting up communication.All for the fail safe that guarantees radio communication.
Carry out at present method that intelligent terminal carries out closely authentication mainly based on the challenge response agreement, no matter physically by which kind of mode connect, as by Bluetooth pairing, or by WiFi communication, or NFC communication.Carry out at present intelligent terminal and carry out closely that the method for key agreement mainly relies on key agreement protocol, be usually directed to cryptography arithmetic.
The defective of challenge response agreement and key agreement protocol is: need the cipher function computing, so amount of calculation is large, power consumption is large, has certain delay.
Summary of the invention
The amount of calculation that the technical problem to be solved in the present invention is to carry out for intelligent terminal in the prior art closely authentication and key agreement is large, has the defective of delay, and the Authentication and Key Agreement method and system between a kind of smart mobile phone of lightweight are provided.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the Authentication and Key Agreement method between a kind of smart mobile phone of lightweight may further comprise the steps:
The data that S1, collection are passed back by transducer: the first intelligent terminal and the second intelligent terminal move according to default mode, and then the first intelligent terminal and the second intelligent terminal are collected respectively the perception data M to this action generation that corresponding transducer is passed back, N;
S2, the data of collecting are exchanged: the first intelligent terminal sends to the second intelligent terminal with the part of data M, and the second intelligent terminal sends to the first intelligent terminal with the part of data N;
S3, the one the second intelligent terminals compare checking to the appropriate section of the perception data that receives and own perception data;
S4, generate arranging key: the first intelligent terminal carries out computing to the part of perception data M by default mode, obtains calculated value, with calculated value as arranging key; The second intelligent terminal carries out computing to the appropriate section of perception data N by default mode, obtains calculated value, with calculated value as arranging key.
Press such scheme, the Authentication and Key Agreement method between described smart mobile phone is characterized in that, the computing described in the S3 is Hash operation.
In order to solve the problems of the technologies described above another technical scheme that adopts be: the Authentication and Key Agreement system between a kind of smart mobile phone of lightweight, this system comprises:
Data collection module is used for collecting the perception data by the action acquisition of sensor senses intelligent terminal;
Communication module is for the exchanges data of perception data between intelligent terminal;
Data processing module is used for the perception data of exchange is verified;
Key production module is used for according to the arranging key between perception data generation intelligent terminal.
Press such scheme, sensor assembly can be gravity sensor, or acceleration sensor, or light sensor, or range sensor.
The operation principle of this system is: A and two intelligent terminals of B are put together and dispose this system, move according to certain mode, action by the sensor senses intelligent terminal on the intelligent terminal also obtains the perception data M that this action produces, N, the data collection module mobile phone is collected the data M that is obtained by transducer, N, communication module sends to the part of data M the data processing module of intelligent terminal 2, simultaneously communication module sends to the data processing module of intelligent terminal 1 with the part of data N, and then data processing module compares checking to the appropriate section of the perception data that receives and own perception data; Last key production module according to perception data, is chosen corresponding part, and it is carried out Hash operation, generates the arranging key between intelligent terminal.
The beneficial effect that the present invention produces is: action when utilizing two intelligent terminals, produce identical sensing data as the authority of authentication and the seed of key, because action is at random, so key also is at random, because other intelligent terminals can't obtain identical perception data, therefore authentication is reliably, and key is safe.The inventive method has been simplified authentication method and the cryptographic key negotiation method of existing intelligent terminal.

Fig. 1 is the method flow diagram of the embodiment of the invention;
Fig. 2 is the system construction drawing of the embodiment of the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, the Authentication and Key Agreement method between a kind of smart mobile phone of lightweight may further comprise the steps:
The data that S1, collection are passed back by transducer: A and two mobile phones of B are put together, and two mobile phones move according to default mode, such as describing a circle, draw a cross etc., and this action will produce certain perception data to gravity sensor.These data are identical for two mobile phones.Right latter two mobile phone is put the perception data M to this action generation that collecting sensor is respectively passed back, N;
S2, the data of collecting are exchanged: mobile phone A sends to mobile phone B with [0,1/4] part of data M, and mobile phone B sends to mobile phone A with [1/4,1/2] part of data N,
S3, the data of exchange are verified: mobile phone A B compares checking to the corresponding part of the perception data that receives and the perception data of having by oneself;
S4, generate arranging key: mobile phone A B to perception data M, N [1/2,1] part is carried out Hash operation, obtains calculated value H, with H as arranging key.
According to the method described above, the present invention also provides the Authentication and Key Agreement system between a kind of smart mobile phone of lightweight, and as shown in Figure 2, this system comprises:
