Description

物联网AP接收数据的分设备加密方法及装置
本发明要求2017年7月14日递交的发明名称为“物联网AP接收数据的分设备加密方法及装置”的申请号201710573347.9的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本申请涉及通信领域，尤其涉及一种物联网AP接收数据的分设备加密方法及装置。
背景技术
物联网是新一代信息技术的重要组成部分，也是“信息化”时代的重要发展阶段。其英文名称是：“Internet of things(IoT)”。顾名思义，物联网就是物物相连的互联网。这有两层意思：其一，物联网的核心和基础仍然是互联网，是在互联网基础上的延伸和扩展的网络；其二，其用户端延伸和扩展到了任何物品与物品之间，进行信息交换和通信，也就是物物相息。物联网通过智能感知、识别技术与普适计算等通信感知技术，广泛应用于网络的融合中，也因此被称为继计算机、互联网之后世界信息产业发展的第三次浪潮。物联网是互联网的应用拓展，与其说物联网是网络，不如说物联网是业务和应用。因此，应用创新是物联网发展的核心，以用户体验为核心的创新2.0是物联网发展的灵魂。
物联网解决的是物物之间的互联以及物物之间的数据交换，现有的物联网在联网时均基于物联网接入点(英文：access point，AP)来接入互联网，现有的物联网AP接收到中继器的数据以后，无法对中继器的数据进行分开加密处理，所以现有的安全性不高。
发明内容
本申请提供一种物联网AP接收数据的分设备加密方法。可以提高物联网 数据的安全性，提高用户体验。
第一方面，提供一种物联网AP接收数据的分设备加密方法，所述方法包括如下步骤：
所述物联网接入点接收中继器发送的数据包；
所述物联网接入点提取所述数据包的中继器的MAC地址，依据所述MAC地址对中继器识别得到中继器的序号，依据所述中继器的序号在预先配置的中继器与加密单元映射表中查询出所述中继器对应的第一加密单元；
所述物联网接入点调用所述第一加密单元对所述数据包进行加密处理；
所述物联网接入点将加密处理后的数据包发送至网关。
可选的，所述方法在所述物联网接入点将加密处理后的数据包发送至网关之前还可以包括：
如第一加密单元对所述数据包加密处理失败，则调用第一加密单元的备用加密单元对所述数据包加密处理。
可选的，所述依据所述MAC地址对中继器识别得到中继器的序号具体包括：
提取所述数据包中的中继器的MAC地址，将该MAC地址与存储的MAC地址与中继器映射表中比对得到该MAC地址对应的中继器的序号。
可选的，所述物联网接入点调用所述第一加密单元对所述数据包进行加密处理具体，包括：
所述物联网接入点从中继器的MAC地址中提取设定位数数字作为秘钥，所述第一加密单元采用所述秘钥对该数据包进行加密处理。
可选的，所述设定位数为4、6或8。
第二方面，提供一种物联网AP接收数据的分设备加密装置，所述装置包括：
接收单元，用于接收中继器发送的数据包；
处理单元，用于提取所述数据包的中继器的MAC地址，依据所述MAC地址对中继器识别得到中继器的序号，依据所述中继器的序号在预先配置的中继器与加密单元映射表中查询出所述中继器对应的第一加密单元；调用所述第一加密单元对所述数据包进行加密处理；
发送单元，用于将加密处理后的数据包发送至网关。
可选的，所述处理单元，还用于如第一加密单元对所述数据包加密处理失败，则调用第一加密单元的备用加密单元对所述数据包加密处理。
可选的，所述处理单元，还用于提取所述数据包中的中继器的MAC地址，将该MAC地址与存储的MAC地址与中继器映射表中比对得到该MAC地址对应的中继器的序号。
可选的，所述处理单元，还用于从中继器的MAC地址中提取设定位数数字作为秘钥，所述第一加密单元采用所述秘钥对该数据包进行加密处理。
可选的，所述设定位数为4、6或8。
第三方面，提供一种计算机可读存储介质，其特征在于，其存储用于电子数据交换的计算机程序，其中，所述计算机程序使得计算机执行第一方面提供的方法。
本发明提供的技术方案的物联网终端将数据包发送至AP以后，AP依据中继器的序号选择与该中继器对应的加密单元，通过该加密单元对数据进行加密，对于物联网来说，中继器无需对加密进行配置，所有的加密设置均在AP，此方式能够有效的降低中继器的成本，并且对于整个物联网来说，由于其一个AP下面可以连接众多的中继器，仅仅对AP配置也可以降低物联网整体的成本，另外，对于AP来说其计算的能力一般强于中继器，那么对运行加密单元时能够减少数据发送的延时，减少网络的时延，提高用户的体验。

下面结合附图对本发明作进一步详细描述。
根据本发明的一个方面，提供了一种物联网AP的上行数据发送方法。其中，该方法应用在如图1所示的物联网络中，如图1所示，该物联网络包括： 物联网终端10、物联网接入点AP20、网关30以及中继器40，上述物联网终端根据不同的情况可以具有不同的表现形式，例如该物联网终端具体可以为：手机、平板电脑、计算机等设备，当然其也可以包含带有联网功能的其他设备，例如智能电视、智能空调、智能水壶或一些物联网的终端设备，上述物联网终端10通过无线方式与中继器40连接，中继器40与AP20连接，AP20通过另一种方式(即与无线方式不同的连接方式)与网关30接入互联网，上述无线方式包括但不限于：蓝牙、WIFI等方式，上述另一种方式可以为，LTE或有线方式，上述网关具体可以为，移动基站、移动中继站、交换机等设备。图1中以有线方式为示例，为了方便表示，这里仅以一根实线表示。
上述网关30根据物联网的大小可以是一台个人电脑(英文：Personal computer，PC)，当然在实际应用中，也可以是多台PC、服务器或服务器群组，本发明具体实施方式并不局限上述网关30的具体表现形式。
参阅图2，图2为物联网AP的数据接收的传输流程图，如图2所示，该流程包括：
步骤S201、物联网终端10将需要发送的数据包通过无线方式发送至中继器40；
步骤S202、中继器将数据包发送至AP20；
步骤S203、AP20将该数据包转发给网关30；
步骤S204、网关30将数据包传输至互联网。
通过上述图1和图2的表示，在数据包的实际传输中，如果AP20与网关30之间出现泄密，那么对于发送的数据包由于没有经过相应的加密处理，所以很容易导致数据的泄漏，容易出现安全性问题。
参阅图3，图3为本发明提供的一种物联网AP接收数据的分设备加密方法，该方法在如图4所示的网络构架下实现，如图4所示，一个AP20下可以连接多个中继器，中继器下可以连接多个物联网接入终端，该AP具体可以为开通热点的手机、提供无线连接的个人电脑或路由器等设备，该方法如图3所示，包括如下步骤：
步骤S301、物联网终端向中继器发送数据包，中继器将数据包发送给AP；
上述步骤S301中的物联网终端具体可以为：手机、平板电脑、计算机等设备，当然其也可以包含带有联网功能的其他设备，例如智能电视、智能空调、智能水壶、智能灯、智能开关或一些物联网的智能设备。
上述步骤S301中物联网终端向中继器发送数据包的方式可以为通过无线连接的方式发送数据包，该无线方式包括但不限于：蓝牙、无线保真(英文：Wireless Fidelity,WIFI)或Zigbee等无线方式，其中，上述WIFI需要遵守IEEE802.11b的标准。
需要说明的是，这里的物联网以及中继器仅仅只是针对无线中继器，因为对于物联网来说，其接入的设备数量众多，对于中继器来说，如果通过有线连接，首先终端的接入数量会有所限制，并且对于家庭来说，均用有线连接，对于家庭用户的布线来说是无法想象的，另外此有线的成本也非常高，所以本发明的技术方案中的中物联网终端与中继器之间的连接仅限无线连接。
步骤S302、AP20接收中继器发送的数据包，AP20提取所述数据包的中继器的MAC地址，依据所述MAC地址对中继器识别得到中继器的序号，依据所述中继器的序号在预先配置的中继器与加密单元映射表中查询出所述中继器对应的第一加密单元。
上述步骤S302中的物联网终端的类型各个厂家可以根据自行的情况进行设置，例如，该物联网终端具体可以包括：智能电灯、智能电视、智能清扫设备、智能睡眠设备，智能监控设备等，其表现的形式可以为多种多样，例如对于智能电灯，该智能电灯包括但不限于：智能台灯，智能吸顶灯，智能壁灯等设备，例如对于智能电视来说，其可以为三星牌智能电视，当然其也可以为夏 普牌智能电视，例如对于智能清扫设备来说，其可以为，智能扫地机器人，当然其还可以包括智能吸尘器、智能垃圾处理器等设备，例如对于智能睡眠设备来说，其可以为：智能床垫、智能沙发等设备，例如对智能监控设备来说或，其可以为，智能血压计，智能温度计等，本发明对上述物联网终端的具体形式以及数量或种类并不限定。
上述步骤中的中继器与加密单元映射表如图5所示，上述映射可以为一一映射，当然也可以为一对多映射等方式。
AP20配置中继器与加密单元之间的多个映射表，多个映射表中每个映射表的中继器与加密单元之间的映射关系不相同，AP20接收网关发送的更新指令，该更新指令包含更新后的映射表的标识以及更新时间，AP20在该更新时间到达时，采用更新后的映射表。可选的，在更新时间到达后，AP20可以同时启用原始的映射表以及更新后的映射表调用两个加密单元，采用两个加密单元分别对数据进行加密后得到第一加密数据包和第二加密数据包发送至网关，AP20接收网关返回的第一加密数据包的响应消息，启动所述第一加密数据包的第一加密单元对应的映射关系。
此技术方案是对映射关系进行更新和维护，这样能够提高安全性，因为固定的映射关系泄密的可能性高，这样影响安全性，而定期的更新维护映射关系，及时所有的映射关系均泄密，但是更新和维护有网关来控制，所以不知道启动那个映射关系的时间也无法对对应的数据包解密，所以其提高了安全性。
AP20配置多个秘钥表，每个秘钥表对应一个加密单元，每个秘钥表包含多个秘钥，AP20接收网关下发的消息中提取消息中携带秘钥标识，选择该标识对应的秘钥采用对应的加密单元进行数据加密。
例如第一秘钥包包含10个秘钥，提取该消息中携带的秘钥标识，例如提取的秘钥为第5秘钥，采用的是第一加密模块，则用第5秘钥采用第一加密模块对数据进行加密。这里对实现多个秘钥的选择提高了安全性。
上述步骤S302中的加密单元具体可以为设置在AP的硬件加密单元，其包含厂家预设设置的加密算法，当然在实际应用中，上述加密单元还可以为配置在AP内的软件加密单元，本发明并不限制上述加密单元的具体表现形式。
上述加密算法包括但不限于：3DES、MD5或RSA等加密算法，本发明 并不局限具体的加密算法。
步骤S303、AP20调用第一加密单元对该数据包进行加密处理；
上述步骤S303的实现方法具体可以为：
例如，第一加密单元为3DES加密单元，则AP20调用3DES加密单元对数据包进行3DES加密处理。例如第一加密单元为RAS加密单元，则AP20调用RAS加密单元对数据包进行RAS加密处理。例如第一加密单元为MD5加密单元，则AP20调用MD5加密单元对数据包进行MD5加密处理。
上述加密处理的具体方式可以参见3DES、RSA以及MD5的相关描述，这里不再赘述。
上述步骤S303的实现方法具体可以为：
AP20调用第一加密单元对该数据包进行加密处理，如加密成功，进行后续步骤S304，如加密不成功，则调用第一加密单元的备用加密单元对该数据包进行加密处理，将采用备用加密单元标识添加到加密处理后的数据包的包头扩展字段。
步骤S304、AP20将该加密处理后的数据包发送至网关。
上述步骤S304的实现方法可以为：
通过另一种方式将加密处理的数据包发送至网关，例如，物联网终端通过WIFI与AP连接，那么AP20可以通过有线方式将数据包发送至网关，当然在实际应用中，AP20也可以通过长期演进(英文：Long Term Evolution，LTE)将加密处理后的数据包发送至网关。当然上述LTE或有限方式以及物联网终端通过WIFI与AP连接的方式仅仅为了举例说明，本发明并不局限上述连接的具体方式。
依据如图3提供的方法，AP依据中继器的序号选择与该中继器对应的加密单元，通过该加密单元对数据进行加密，对于物联网来说，中继器无需对加密进行配置，所有的加密设置均在AP，此方式能够有效的降低中继器的成本，并且对于整个物联网来说，由于其一个AP下面可以连接众多的中继器，仅仅对AP配置也可以降低物联网整体的成本，另外，对于AP来说其计算的能力一般强于中继器，那么对运行加密单元时能够减少数据发送的延时，减少网络的时延，提高用户的体验。
参阅图6，图6为本发明提供的一种物联网AP接收数据的分设备加密方法，该方法在如图4所示的网络构架下实现，如图4所示，一个AP20下可以连接多个中继器，中继器下可以连接多个物联网接入终端，该AP具体可以为开通热点的手机、提供无线连接的个人电脑或路由器等设备，该方法如图6所示，包括如下步骤：
步骤S601、物联网终端向中继器发送数据包；
上述步骤S601中的物联网终端具体可以为：手机、平板电脑、计算机等设备，当然其也可以包含带有联网功能的其他设备，例如智能电视、智能空调、智能水壶、智能灯、智能开关或一些物联网的智能设备。
上述步骤S601中物联网终端向中继器发送数据包的方式可以为通过无线连接的方式发送数据包，该无线方式包括但不限于：蓝牙、无线保真(英文：Wireless Fidelity,WIFI)或Zigbee等无线方式，其中，上述WIFI需要遵守IEEE802.11b的标准。
需要说明的是，这里的物联网以及中继器仅仅只是针对无线中继器，因为对于物联网来说，其接入的设备数量众多，对于中继器来说，如果通过有线连接，首先终端的接入数量会有所限制，并且对于家庭来说，均用有线连接，对于家庭用户的布线来说是无法想象的，另外此有线的成本也非常高，所以本发明的技术方案中的中物联网终端与中继器之间的连接仅限无线连接。
步骤S602、AP20接收中继器发送的数据包，AP20提取所述数据包的中继器的MAC地址，依据所述MAC地址对中继器识别得到中继器的序号，依据所述中继器的序号在预先配置的中继器与加密单元映射表中查询出所述中继器对应的第一加密单元。
上述步骤S602中的物联网终端的类型各个厂家可以根据自行的情况进行设置，例如，该物联网终端具体可以包括：智能电灯、智能电视、智能清扫设备、智能睡眠设备，智能监控设备等，其表现的形式可以为多种多样，例如对于智能电灯，该智能电灯包括但不限于：智能台灯，智能吸顶灯，智能壁灯等 设备，例如对于智能电视来说，其可以为三星牌智能电视，当然其也可以为夏普牌智能电视，例如对于智能清扫设备来说，其可以为，智能扫地机器人，当然其还可以包括智能吸尘器、智能垃圾处理器等设备，例如对于智能睡眠设备来说，其可以为：智能床垫、智能沙发等设备，例如对智能监控设备来说或，其可以为，智能血压计，智能温度计等，本发明对上述物联网终端的具体形式以及数量或种类并不限定。
上述步骤中的中继器与加密单元映射表如图5所示，上述映射可以为一一映射，当然也可以为一对多映射等方式。
上述步骤S602中的加密单元具体可以为设置在AP的硬件加密单元，其包含厂家预设设置的加密算法，当然在实际应用中，上述加密单元还可以为配置在AP内的软件加密单元，本发明并不限制上述加密单元的具体表现形式。
上述加密算法包括但不限于：3DES、MD5或RSA等加密算法，本发明并不局限具体的加密算法。
步骤S603、AP20调用第一加密单元对该数据包进行加密处理；
上述步骤S603的实现方法具体可以为：
AP20提取所述数据包中的中继器的MAC地址，将该MAC地址与存储的MAC地址与中继器映射表中比对得到该MAC地址对应的中继器的序号，从中继器的MAC地址中提取设定位数数字作为秘钥，所述第一加密单元采用所述秘钥对该数据包进行加密处理。
上述设定数字具体可以为4、6或8，因为对于MAC地址来说，其具有48bit的数值，即由48位，那么取设定数字时，一定需要倍48整除，否则会出现私钥位数不一致的问题。当然在实际应用中，可以将将提取设定位数数字转换成10进制数，然后采用10进制数作为私钥。当然上述10进制数也可以采用16进制数进行替换。上述提取设定位数数字可以是按顺序提取，例如，第一次提取前8位，第二次提取9-17位，当然也可以跨位数提取或采用其他的位数提取方式，本发明具体实施方式并不局限上述位数的具体提取方式。
上述步骤S603的实现方法具体可以为：
例如，第一加密单元为3DES加密单元，则AP20调用3DES加密单元对数据包进行3DES加密处理。例如第一加密单元为RAS加密单元，则AP20 调用RAS加密单元对数据包进行RAS加密处理。例如第一加密单元为MD5加密单元，则AP20调用MD5加密单元对数据包进行MD5加密处理。
上述加密处理的具体方式可以参见3DES、RSA以及MD5的相关描述，这里不再赘述。
上述步骤S603的实现方法具体可以为：
AP20调用第一加密单元对该数据包进行加密处理，如加密成功，进行后续步骤S304，如加密不成功，则调用第一加密单元的备用加密单元对该数据包进行加密处理，将采用备用加密单元标识添加到加密处理后的数据包的包头扩展字段。
步骤S604、AP20将该加密处理后的数据包发送至网关。
上述步骤S604的实现方法可以为：
通过另一种方式将加密处理的数据包发送至网关，例如，物联网终端通过WIFI与AP连接，那么AP20可以通过有线方式将数据包发送至网关，当然在实际应用中，AP20也可以通过长期演进(英文：Long Term Evolution，LTE)将加密处理后的数据包发送至网关。当然上述LTE或有限方式以及物联网终端通过WIFI与AP连接的方式仅仅为了举例说明，本发明并不局限上述连接的具体方式。
依据如图6提供的方法，AP依据中继器的序号选择与该中继器对应的加密单元，通过该加密单元对数据进行加密，对于物联网来说，中继器无需对加密进行配置，所有的加密设置均在AP，此方式能够有效的降低中继器的成本，并且对于整个物联网来说，由于其一个AP下面可以连接众多的中继器，仅仅对AP配置也可以降低物联网整体的成本，另外，对于AP来说其计算的能力一般强于中继器，那么对运行加密单元时能够减少数据发送的延时，减少网络的时延，提高用户的体验。
