A kind of remote control thereof as shown in Figure 1, the communication between remote control equipment and electronic equipment can be realized, remote control equipment is a kind of RF remote control equipment, such as RF telepilot, electronic equipment possesses wireless network card chip, can be such as the TVs such as smartTV or Set Top Box, and remote control equipment adopts the wireless protocols transmission of 2.4Ghz frequency band, the two realizes data interaction based on WIFI direct communication protocol, specifically comprises:
Step S101: when described remote control equipment detects the first key commands that its key-press matrix sends, request and described electronic equipment match.
Wherein, the first key commands is the command information that user sends when being connected with electronic equipment by remote control equipment, and the specifically instruction request of pressing in the key-press matrix of remote control equipment that is specially carries out matching with electronic equipment the button be connected.
Step S102: when the pairing request response of described electronic equipment to remote control equipment is effective, described remote control equipment and electronic equipment carry out key change.
In step S102, about how judging that electronic equipment to the pairing request response of remote control equipment effectively, comprises the steps:
Step S121: when described electronic equipment is in response to described pairing request, feed back the first confirmation signal to described remote control equipment;
Step S122: the signal intensity of the first confirmation signal received when described remote control equipment is more than the first threshold value, and described electronic equipment to the pairing request response of remote control equipment effectively.
How to carry out key change about described remote control equipment and electronic equipment, specifically comprise the steps:
Step S123: when described remote control equipment detects the second key commands that its key-press matrix sends in setting-up time, described remote control equipment sends service selection request;
Step S124: when the service selection request response of described electronic equipment to remote control equipment is effective, described remote control equipment and electronic equipment carry out key change.
Wherein, the respective services that the display screen display of carrying out matching rear remote control equipment due to remote control equipment and electronic equipment provides, served according to required selection by user, on key-press matrix, button is selected and is formed described second key commands, according to the second key commands, remote control equipment sends service selection request and is again connected with electronic equipment.

How to judge in step S124 that described electronic equipment is to the service selection request response of remote control equipment effectively then similar step S121 ~ S122, comprises the following steps:
Step S124.1: when described electronic equipment is in response to described service selection request, feed back the second confirmation signal to described remote control equipment;
Step S124.2: the signal intensity of the second confirmation signal received when described remote control equipment is more than the second threshold value, and described electronic equipment to the service selection request response of remote control equipment effectively.
In above-mentioned steps, the first threshold value and the second threshold value are all measure the one of signal intensity.In environment residing for remote control equipment except with its sharing electron equipment except also there are other electronic equipments, each electronic equipment possesses and has compatible wireless network card chip, the request response that can send remote control equipment feedback acknowledgment signal, each electronic equipment now existed in remote control equipment and environment matches the problem of connection error.
Consider: electronic equipment is by antenna transmission wireless signal, the signal of aerial radiation often transmits certain distance in space and will produce certain decay, can think on the ground of infinity and decay to 0, only in the certain limit of signal source, signal just has higher intensity, utilize this principle that above-mentioned threshold value is set to determine that the distance between electronic equipment and remote control equipment is within the specific limits, eliminate the electronic equipment beyond distance range with this, prevent remote control equipment and other electronic equipments from matching the problem of connection error.More specifically, we from following formula, can obtain the concrete numerical value of threshold settings:
PL(dB)=46+10×n×log D（m） （1）
Formula (1) is the experimental formula that radio signal attenuation calculates.Wherein, PL (dB) is for path D(m) prolongation and the path attenuation situation produced, measure with unit dB; D is travel path, and m is the length (with the distance of signal source) of travel path; N is decay factor.For different wireless environments, the value of decay factor n is different; In free space, square being directly proportional of path attenuation and distance, namely decay factor is 2.In buildings, distance obviously will be greater than free space to the impact of path loss; Numerical value 46 is the empirical constant in formula (1).In general, be 2.0 ~ 2.5 for the value of n under Full-open environment; Be 2.5 ~ 3.0 for the value of n under semi-open environment; Be 3.0 ~ 3.5 for the value compared with n under enclosed environment.Calculate with indoor 2m distance, n value is 3, then attenuation is: PL=46+10 × 3 × log2=55dB, calculates with antenna delivery outlet power 10dBm, then, after indoor 50m decay, signal intensity is: 10dBm-55dB=-45dBm.In the present embodiment, the first threshold value and the second threshold value can setting signal intensity be all-45dBm.
Step S103: when described key change success, described remote control equipment and electronic equipment carry out data interaction.

The process be encrypted data can, see Fig. 2, be AES encryption, as can be known from Fig. 2, protocol layer encryption to as if 128 bit data:
Steps A 1, first divides into groups (forming the matrix that row, column is formed) to 128 bit data, this multi-group data and key is carried out XOR,
Steps A 2, carries out the conversion of S box, line translation, rank transformation to this multi-group data successively, and again the multi-group data after conversion and key is carried out XOR; Repeat this process, until eliminate the row in grouping;
Steps A 3, again the conversion of S box, line translation are carried out to this multi-group data (only the matrix of surplus row), multi-group data after this being converted and key carry out XOR, and form 128 final bit encryption data, these 128 bit encryption data are data that protocol layer is sent to MAC layer.
After transmitting element sends the first order, opening timing device while wait electronic equipment returns MAC layer confirmation of receipt (the 3rd confirmation signal), timer is the stand-by period computing unit on control module (MCU), acknowledge receipt of in during electronic equipment returns confirmation (or confirming bag) in MAC layer, stand-by period is calculated, if wait timeout, MAC layer does not receive the confirmation that electronic equipment returns, then repeat: the data after encryption are packed by MAC layer again, and after adding check bit, be sent to the data transmission unit of remote control equipment, and opening timing device again.If MAC layer receives the confirmation that electronic equipment returns, send end.
Step S132: when the data receipt unit of described remote control equipment receives the second order of the described remote control equipment of sensing that described electronic equipment sends, the protocol stack of remote control equipment by described exchange double secret key described in the second order be decrypted and perform the corresponding actions in the second order.
What step S132 described is the process that remote control equipment carries out message sink, wherein:
The receiving element of remote control equipment receives WIFI signal, and this WIFI signal is the sensing remote control equipment of electronic equipment transmission and makes remote control equipment do the order of specific action, i.e. described second order.First the protocol stack of remote control equipment confirms in MAC layer whether the target MAC (Media Access Control) address on the packet of WIFI signal transmission is identical with Self address and verifies errorless, Protocol layer data is uploaded to protocol layer and returns confirmation, otherwise abandoning; The data being successfully uploaded to protocol layer are decrypted by the key of protocol layer according to pairing, are verified, and be uploaded to application layer, otherwise abandon after confirmation is errorless; The data received then are converted to the instruction that can perform corresponding actions by application layer.
Can, see Fig. 3, be the inverse process of Fig. 2 to the process of decrypt data in protocol layer:
Step B1, first divides into groups (only the matrix of surplus row) to 128 bit encryption data, this multi-group data and key is carried out XOR,
Step B2, carries out the conversion of anti-S box, anti-line translation to this multi-group data (only the matrix of surplus row);
Step B3, carries out the conversion of anti-S box, anti-line translation, anti-rank transformation to the multi-group data after inverse transformation successively, and again the multi-group data (forming the matrix that row, column is formed) after inverse transformation is carried out XOR with key; Repeat this process, until recover to obtain 128 data decryptions, these 128 bit encryption data are data that protocol layer is sent to application layer.
