Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the nfc cooperative relay system in this embodiment includes a nfc cooperative relay system formed by a first nfc device, a second nfc device, an nfc relay control node, N nfc relay nodes, and an authentication mechanism, where the first nfc device and the second nfc device are respectively connected to the authentication mechanism, and the N nfc relay nodes are respectively connected to the nfc relay control node.
As shown in fig. 2, the cooperative relay communication method of the near field communication device in this embodiment sequentially includes the following steps:
step 1, a first near field communication device collects human body magnetic field data of a legal owner in real time within a preset time period, a human body magnetic field database of the legal owner within each preset time period is built, and the built human body magnetic field database is used as identity identification information of the legal owner; the preset time period comprises a first preset time period and a second preset time period, and the first preset time period is 06: 00-18: 00; the second preset time period is 18:00 to 06:00 the next day;
because the magnetic field of each human body is different, the human body magnetic field is used as the unique biological characteristic of each human body, and the human body magnetic field can be used as the human body biological characteristic information of identity recognition like finger fingerprints. The intensity of the human body magnetic field data is not constant in each time period, so in this embodiment, two time periods are preset for the human body magnetic field data, that is, the preset time period includes a first preset time period and a second preset time period, and the first preset time period is 06:00 to 18: 00; the second preset time period is 18:00 to 06:00 the next day;
step 2, after the first near field communication equipment builds a human body magnetic field database of a legal owner, the first near field communication equipment collects body odor data of the legal owner, receives fingerprint information and vein information corresponding to each finger of the legal owner, and builds a body odor database of the legal owner of the first near field communication equipment, and a fingerprint information database and a vein information database corresponding to each finger; the first near field communication equipment gives the human body magnetic field of a legal owner of the first near field communication equipment a first priority for identity recognition, and the body odor data has a second priority for identity recognition; in the process of identity recognition, the first priority has higher recognition reliability than the second priority;
the body odor of each person is different, and the body odor data of the person is the same as the biological characteristics of a magnetic field, fingerprints, a face, an iris and the like of the person and also has unique non-replicability, so the body odor data of the person can be used as the characteristic information of identity recognition;
regarding the priority problem of the human body magnetic field and the body odor data at the time of identification, for example, when the first near field communication device judges that the acquired human body magnetic field of the operator belongs to the magnetic field data of its legitimate owner and judges that the acquired body odor data does not belong to the body odor data of its legitimate owner, the first near field communication device finally judges that the operator is its legitimate owner;
step 3, the first near field communication equipment displays a preset number of allowed near field communication input boxes on a touch display screen of the first near field communication equipment to a legal owner of the first near field communication equipment, and each allowed near field communication input box corresponds to seven basic color lists for optional selection; the seven basic colors in the basic color list are respectively red, orange, yellow, green, cyan, blue and purple, and each allowable near field communication input box corresponds to a group of near field communication allowable colors; each set of near field communication allowed colors is any combination of the seven basic colors;
for example, the first near field communication device displays 3 near field communication enabled input boxes on its touch display screen, the 3 near field communication enabled input boxes numbering a 01 input box, a 02 input box and a 03 input box, respectively; wherein:
seven basic colors of red, orange, yellow, green, cyan, blue and purple are corresponded in the 01 input box,
the 02 input box is corresponding to seven basic colors of red, orange, yellow, green, cyan, blue and purple,
seven basic colors of red, orange, yellow, green, cyan, blue and purple are correspondingly arranged in the 03 input box;
the basic colors provided in the 3 near field communication enabled input boxes are the same, and the legal owner of the first near field communication device may select at least one basic color in the 01 input box as a group of near field communication enabled colors corresponding to the 01 input box, for example, red alone as a group of near field communication enabled colors, or a combination of three basic colors, namely, red, orange and yellow, as a group of near field communication enabled colors corresponding to the 01 input box; similarly, the 02 input box and the 03 input box can be set as required to form corresponding near field communication allowed colors; for example, the set of near field communication permission colors corresponding to the 01 input box is red, red and yellow, the set of near field communication permission colors corresponding to the 02 input box is orange and yellow, and the set of near field communication permission colors corresponding to the 03 input box is blue and purple.
Step 4, according to the basic color list corresponding to each allowed near field communication input box on the touch display screen, a legal owner of the first near field communication equipment sequentially selects basic color combinations with custom kinds of numbers as the near field communication allowed colors of each allowed near field communication input box respectively, and the first near field communication equipment correspondingly stores the near field communication allowed colors corresponding to each allowed near field communication input box respectively; the legal owner of the first near field communication equipment correspondingly inputs the whole combination of the groups of near field communication permission colors in each permission near field communication input box to form a secondary confirmation permission near field communication password of the first near field communication equipment for near field communication;
for example, in the 3 near field communication permission input boxes illustrated in step 3, the secondary confirmation permission near field communication password of the first near field communication device is an integral combination of the respective groups of near field communication permission colors corresponding to the three input boxes, that is, the secondary confirmation permission near field communication password of the first near field communication device is "red, yellow; orange and yellow; blue, violet ".
In addition, as a safer near field communication protection method, the secondary confirmation of the first near field communication equipment allows the near field communication password to be the integral combination of all groups of near field communication allowed colors which are sequentially and correspondingly input by a legal owner in each allowed near field communication input box according to the sequence; that is, the order of the basic colors also has a limiting effect on the setting of the secondary confirmation permission near field communication password, and even if the basic colors selected from the groups of near field communication permission colors are consistent, the authentication of the secondary confirmation permission near field communication password by the first near field communication device cannot be performed as long as the order of the basic color input is not right; for example, the second confirmation set by the rightful owner of the first near field communication device allows the near field communication password to be "red, yellow; orange and yellow; blue, purple ", if someone, including the legitimate owner of the first near field communication device, the second confirmation entered allows the near field communication password to be" red, yellow, red "; orange and yellow; blue and purple, the person still cannot pass the secure near field communication authentication of the first near field communication device, and the first near field communication device does not start a near field communication response, so that the communication information of the first near field communication device can be effectively ensured;
because each group of near field communication permission colors corresponding to each permission near field communication input box is set by the legal owner of the first near field communication equipment, and the color in each group of near field communication permission colors is randomly set by the legal owner of the first near field communication equipment, the final near field communication permission color is only known by the legal owner of the first near field communication equipment, and other persons are difficult to guess or crack to obtain the correct near field communication permission color, so that the safety performance of the second confirmation permission near field communication password of the first near field communication equipment is improved, and the authentication accuracy of the first near field communication equipment on whether the operator has legal identity is further enhanced;
step 5, the first near field communication equipment sends the real identity identification number to the certification authority, and the certification authority generates an anonymous identity identification number for near field communication of the first near field communication equipment; the second near field communication equipment sends the real identity identification number to the certification authority, and the certification authority generates an anonymous identity identification number for near field communication of the second near field communication equipment; wherein:
the real ID number of the first near field communication equipment is marked asThe anonymous identity of the first near field communication device is marked asThe true identity number of the second near field communication device is marked asThe anonymous identity of the second near field communication device is marked asThe certification authority is marked as TSM;
wherein, sH (·) is a hash anonymity function, which is the prior art and is not described herein in too much detail;
when the first near field communication equipment communicates with the near field communication relay node, the near field communication relay node can only obtain the anonymous identity identification number of the first near field communication equipmentThus canThe first near field communication equipment is prevented from being falsely identified by other illegal third parties to try to perform communication interaction with the authentication mechanism and the near field communication relay node, so that the information safety of the first near field communication equipment is ensured;
step 6, when the first near field communication device and the second near field communication move to a preset relay distance, and any one near field communication relay node in the N near field communication relay nodes detects a near field communication radio frequency signal, the near field communication relay node which detects the near field communication radio frequency signal sends a cooperative relay notification message to each near field communication relay node in the remaining N-1 near field communication relay nodes;
step 7, after the remaining N-1 near field communication relay nodes respectively receive the cooperative relay notification information, the N near field communication relay nodes start respective self-checking operations and respectively correspondingly send self-checking results to the near field communication relay control nodes to obtain the optimal near field communication relay node so as to start a cooperative relay process; the self-checking operation information comprises respective signal-to-noise ratio, power consumption value, distance from the self to the first near field communication equipment and distance from the self to the second near field communication equipment; the cooperative relay process of the N near field communication relay nodes comprises the following steps 7-1 to 7-4:
7-1, respectively acquiring the signal-to-noise ratio of the N near field communication relay nodes, and calculating the signal-to-noise ratio weight of each near field communication relay node by the near field communication relay control node; wherein:
wherein,the signal to noise ratio weight and SNR of the ith near field communication relay nodeiThe signal-to-noise ratio of the ith near field communication relay node;
7-2, respectively acquiring the power consumption values of the N near field communication relay nodes, and calculating the power consumption value weight of each near field communication relay node by the near field communication relay control node; wherein:
wherein,is the power consumption value weight of the ith near field communication relay node, EiThe power consumption value of the ith near field communication relay node is obtained;
7-3, respectively acquiring the distance from the N near field communication relay nodes to the first near field communication equipment and the distance from the N near field communication relay nodes to the second near field communication equipment, and calculating the relay distance weight of each near field communication relay node by the near field communication relay control node; wherein:
wherein,a relay distance weight of the ith near field communication relay node, Di1Is the distance value from the ith near field communication relay node to the first near field communication device, Di2For the distance value from the ith near field communication relay node to the second near field communication device, max (D)i1,Di2) Represents the distance Di1And a distance Di2Maximum value of (1), min (D)i1,Di2) Represents the distance Di1And a distance Di2Minimum value of (1);
