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，提供了一种物联网终端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以及无线接入控制器30，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智能设备，上述物联网终端10通过无线方式与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12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。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。
上述无线接入控制器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或服务器，本发明具体实施方式并不局限上述无线接入控制器的具体表现形式。
参阅图2，图2为物联网终端的上行数据发送的传输流程图，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AP20；
步骤S202、AP20将该数据包转发给无线接入控制器30；
步骤S203、无线接入控制器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与无线接入控制器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终端基于类型的上行数据加密控制方法，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下可以连接多个物联网终端，该AP具体可以为中继站，当然在实际应用中也可以为路由器或其他的具有无线连接以及数据转发功能的网络设备，例如开通热点的手机、提供无线连接的个人电脑等设备，该方法如图3所示，包括如下步骤：
步骤S301、物联网终端获取待发送的数据包；
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。
步骤S302、所述物联网终端识别所述数据包的类型，依据所述类型在预先配置的类型与加密单元映射表中查询出所述类型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，该物联网终端的类型具体可以包括：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类型以及类型的数量或种类并不限定。
上述数据包的类型包括但不限于：控制指令类型、参数类型、反馈类型，其中，控制指令类型对应一些协议规定的控制命令，该协议根据不同的连接方式对应不同的协议，这里并不限于该协议的具体表现形式。该参数类型可以为物联网终端需要反馈的参数，包括但不限于：速度参数、温度参数、时间参数等等，该反馈类型包括单不限于，网络侧设备需要物联网终端反馈的的数据的类型。
上述步骤中的类型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S302中的加密单元具体可以为设置在终端的硬件加密单元，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终端内的软件加密单元，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、物联网终端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，则物联网终端调用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，则物联网终端调用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，则物联网终端调用MD5加密单元对数据包进行MD5加密处理。
上述加密算法包括但不限于：三重数据加密算法块密码(英文：riple Data Encryption Algorithm，3DES)、消息摘要算法(英文：Message Digest Algorithm，MD5)或RSA(Rivest,Shamir,Adleman)等加密算法，本发明并不局限具体的加密算法。例如3DES是三重数据加密算法块密码的通称。它相当于是对每个数据块应用三次DES加密算法。由于计算机运算能力的增强，原版DES密 码的密钥长度变得容易被暴力破解；3DES即是设计用来提供一种相对简单的方法，即通过增加DES的密钥长度来避免类似的攻击。
上述步骤S303的实现方法具体可以为：
物联网终端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、物联网终端将该加密处理后的数据包向网络侧设备发送。
上述步骤S304中物联网终端向AP20(一种网络侧设备)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AP仅仅只是针对无线AP，因为对于物联网来说，其接入的设备数量众多，对于AP来说，如果通过有线连接，首先AP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AP之间的连接仅限无线连接。
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无线接入控制器，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无线接入控制器，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无线接入控制器。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，如图3所示提供的技术方案的物联网终端获取待发送的数据包以后，物联网终端依据该数据包的类型查询出该类型对应的加密单元，通过该加密单元对数据进行加密，对于物联网来说，物联网AP无需对加密进行配置，所有的加密设置均在物联网终端，此方式能够有效的降低物联网终端的成本，并且对于整个物联网来说，物联网终端为物联网数据中的起点， 通过对其加密能够从源头对数据进行加密，提高了安全性，提高用户的体验。

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无线接入控制器，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无线接入控制器，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无线接入控制器。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。
