S3、在检测到两个振动信息的编码序列完全相同时，将所述编码序列作为共享密钥建立所述触摸设备和所述可穿戴设备的通信连接。
需要说明的是，触摸设备中安装有振动马达和三轴加速计，可穿戴设备中安装有三轴加 速计。可穿戴设备佩戴于用户穿戴部位上，其中，用户穿戴部位一般为用户手部，可穿戴设备一般佩戴于用户手部的手腕处。在用户穿戴部位触摸在触摸设备上时，触摸设备中的振动马达发出振动信号，该振动信号刺激触摸设备振动，进而刺激触摸在触摸设备上的用户穿戴部位振动。触摸设备中的三轴加速计测量触摸设备的振动响应以获得振动信息，可穿戴设备中的三轴加速计测量用户穿戴部位的振动响应以获得振动信息。其中，用户穿戴部位在触摸设备上的触摸姿势、力度和触摸点不同，测量到的振动信息也不同。
其中，触摸设备中的振动马达通过扫描预设频率范围内的振动频率以发出振动信号。频率范围越大，获取的振动信息越完整，但由于三轴加速计能够测量到的最大频率受限于其采样频率，且对于给定的频率扫描速度，振动时长与频率范围成正比，因此，需设定合理的频率范围。在设定好频率范围后，需尽可能提高频率扫描速度以降低振动时长。但由于振动马达在每次改变频率后，需一段时间才能达到稳态，而稳态时测量到的数据更加准确，因此，为了使三轴加速计尽可能测量稳态时的数据，在振动马达每次改变频率前都需留有足够长的时间。优选地，设定频率范围为20hz到125hz，设定振动时长为1.75s，即设定振动马达在1.75s内从20hz扫描到125hz。
在获取两个振动信息后，分别对每个振动信息进行编码以提取出两个设备之间的互信息，进而将该互信息作为共享密钥建立触摸设备和可穿戴设备之间的安全信道，实现两个设备的配对。在配对成功后，两个设备之间的信息传输仍使用原来的通信信道，如蓝牙、WIFI等。采用触摸设备与用户穿戴部位的共振方式来实现触摸设备和可穿戴设备的配对，提高设备配对的安全性，且大多数可穿戴设备中均具有三轴加速计，大多数智能设备中均具有振动马达和三轴加速计，从而广泛适用于可穿戴设备和智能设备中。
进一步地，所述每个振动信息均包括所述预设频率范围内的各个振动频率及其所对应的加速计数据；
所述分别对每个振动信息进行编码，获得所述每个振动信息的编码序列，具体包括：
分别从所述每个振动信息中的各个振动频率及其所对应的加速计数据中识别出所有共振频率和所有反共振频率；
分别对所述每个振动信息中的所有共振频率和所有反共振频率所处的相对位置进行编码，获得所述每个振动信息的编码序列。
需要说明的是，触摸设备中的振动马达在扫描预设频率范围内的振动频率时，触摸设备和可穿戴设备中的三轴加速计各自测量其各个振动频率所对应的加速计数据，从而获得预设频率范围内的各个振动频率及其所对应的加速计数据，即振动信息。在获取振动信息后，扫描振动信息中的整个频率范围，标记出所有共振频率和所有反共振频率，然后将这些共振频 率和反共振频率的相对位置转换为比特序列，从而获得每个振动信息的编码序列。两个振动信息在频域上为两条极相似的曲线，采用共振频率和反共振频率的相对位置进行编码，提高设备的匹配率。
进一步地，所述分别从所述每个振动信息中的各个振动频率及其所对应的加速计数据中识别出所有共振频率和所有反共振频率，具体包括：
采用预设的滑动窗分别在所述每个振动信息中的整个频率范围内滑动，并从每个滑动窗中最多选取一个局部最大加速计数据和一个局部最小加速计数据；
将所述局部最大加速计数据所对应的振动频率作为共振频率，并将所述局部最小加速计数据所对应的振动频率作为反共振频率，以获得所述每个振动信息中的所有共振频率和所有反共振频率。
需要说明的是，每个振动信息在频域上均为一条正弦曲线，可采用局部最大值和局部最小值的方式来识别共振频率和反共振频率。先设定一个滑动窗在振动信息的整个频率范围内滑动，并找到每个滑动窗的极大值和极小值。由于局部方差的影响，在共振频率或反共振频率附近可能会有多个极值，为避免极值的重复选取，在每个滑动窗中最多选取一个最优的极大值和一个最优的极小值，而舍弃其他极值。在选取极值后，将选取的极大值所对应的振动频率识别为共振频率，将选取的极小值所对应的振动频率识别为反共振频率。如图2所示，选取整个频率范围20hz到125hz内的极值，并将极大值所对应的振动频率R1、R2、R3、R4识别为共振频率，将极小值所对应的振动频率A1、A2、A3识别为反共振频率，从而获取每个振动信息中的所有共振频率和反共振频率。
进一步地，所述分别对所述每个振动信息中的所有共振频率和所有反共振频率所处的相对位置进行编码，获得所述每个振动信息的编码序列，具体包括：
将所述每个振动信息中的整个频率范围划分为N个频段；其中，N≥1；
依次检测每个频段中是否具有共振频率或反共振频率；
若是，则将所述频段划分为M个子频段，并将所述共振频率或所述反共振频率编码为其所处子频段所对应的码字；其中，M≥1；
若否，则将所述频段编码为预先定义的码字；
将所述每个振动信息的所有码字进行排列，获得所述每个振动信息的编码序列。
需要说明的是，将每个振动信息中的整个频率范围均匀划分为N个频段以对共振频率和反共振频率在频段中的相对位置进行编码。其中，频段的划分个数N与共振频率(或反共振频率)的个数呈正相关，例如，20-125hz频段具有4-8个共振频率(或反共振频率)，因此将频率范围划分为6个频段。划分后，依次检测每个频段，若频段中没有共振频率或反共振频 率，则将该频段编码为预先定义的码字，如采用两个比特“00”进行编码；若频段中具有共振频率或反共振频率，则将该频段再均匀划分为M个子频段，一般划分为3个子频段，并给3个子频段分别设定相应的码字，如“01”、“11”和“10”，再检测共振频率或反共振频率位于哪个子频段中，并将共振频率或反共振频率编码为该子频段所对应的码字。若一个频段中具有多个共振频率(或反共振频率)，则选择具有更大(或更小)振幅的共振频率(或反共振频率)来进行编码。编码后，采用相同的排列方式对两个振动信息中的所有码字进行排列，从而获得两个振动信息的编码序列。采用共振频率和反共振频率的相对位置进行编码，可以避免窃听者通过推测编码序列中的码字导致的信息泄露，进一步提高设备配对的安全性。
进一步地，所述设备配对方法还包括：
在检测到所述两个振动信息的编码序列不相同时，分别将每个编码序列中不相同的码字替换为所述编码序列中距离其k比特的码字，并继续对替换后的两个编码序列进行比较。
需要说明的是，在编码后，由于噪音和不匹配的局部方差的影响，两个振动信息的编码序列在一些比特位上可能存在不同。为了纠正这些不同的比特位，采用错误校正码，如前向纠错码FEC来将不同的比特位替换为统一的码字。具体为，采用一个解码器将不同的比特位映射到其所在编码序列中距离其k比特的码字上。由于编码序列中仅存在少数不同的比特位，因此不同的比特位很可能被映射到相同的码字上。替换后，再对两个编码序列进行比较，若两个编码序列完全相同，则将该编码序列作为共享密钥建立触摸设备和可穿戴设备之间的通信连接；若两个编码序列仍不相同，可继续进行替换。
进一步地，在所述分别对每个振动信息进行编码，获得所述每个振动信息的编码序列之前，还包括：
分别对所述每个振动信息进行过滤。
需要说明的是，由于在配对过程中，用户穿戴部位的运动是不可避免的，使得振动信息的获取收到运动伪影的干扰。而运动引起的加速度一般比振动引起的加速度大很多，使得在获取振动信息时很难提取振动引起的加速度。但是，运动伪影的频率集中在30hz到15hz的低频率范围内，因此，在对振动信息进行编码前，还需对振动信息进行过滤，获取所需频率范围内的各个振动频率及其对应的加速计数据。其中，所需频率范围的最小振动频率一般超过20hz，以避免与用户穿戴部位的运动频率重叠。同时，由于局部方差的影响，一个共振频率或反共振频率附近具有多个峰值，因此在编码前采用一个移动平均滤波器来消除这些局部方差。
本发明实施例提供的设备配对方法，能够通过用户穿戴部位对触摸设备的触摸而引起触摸设备的振动，并带动用户穿戴部位的振动，进而获取触摸设备和用户穿戴部位的振动信息 进行编码，以建立触摸设备和可穿戴设备的通信连接，实现两个设备的配对，有效提高设备配对的安全性，且无需在两个设备中安装特殊传感器，适用范围广；在对振动信息进行编码时，采用对振动信息中的共振频率和反共振频率的相对位置进行编码，有效防止窃听，进一步提高设备配对的安全性。
