Description
本发明要求2017年7月19日递交的发明名称为“一种物联网中继器数据的分时段加密方法及装置”的申请号201710588676.0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。
本申请涉及通信领域,尤其涉及一种物联网中继器数据的分时段加密方法及装置。
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下有多个中继器,中继器接收到相应的数据以后,不会对数据进行加密处理,这样容易出现物联网设备的泄密,导致用户隐私数据泄露,用户体验度不高。

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,提供了一种物联网中继器的数据发送方法。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AP连接,其连接的方式可以为无线方式,也可以为有限方式,上述无线方式包括但不限于:蓝牙、WIFI等方式,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。
上述中继器40根据不同的场景可以为多种设备,例如手机、智能手表等等设备。
参阅图2,图2为物联网中继器的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中继站40;
步骤S202、中继站将数据包转发至物联网接入点;
步骤S203、物联网接入点将数据包传输至网关。
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与中继器之间出现泄密,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中继器数据的分时段加密方法,该方法在如图4所示的网络构架下实现,如图4所示,一个中继器40下可以连接多个物联网终端,该中继器具体可以为开通热点的手机、提供无线连接的个人电脑、转发设备等,该方法如图3所示,包括如下步骤:
步骤S301、物联网终端向物联网接入点40发送数据包;
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。
上述步骤S301中物联网终端向物联网终端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,这里的物联网以及物联网终端仅仅只是针对无线物联网终端,因为对于物联网来说,其接入的设备数量众多,对于物联网终端来说,如果通过有线连接,首先物联网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物联网终端之间的连接仅限无线连接。
步骤S302、物联网中继器提取该数据包的发送时间,依据该发送时间确定该工作时段物联网终端的工作时段,依据该工作时段在预先配置的工作时段与加密单元映射表中查询出该工作时段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。
上述步骤中的工作时段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物联网中继器的硬件加密单元,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、物联网中继器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,则物联网中继器调用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,则物联网中继器调用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,则物联网中继器调用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:
物联网中继器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、物联网中继器将该加密处理后的数据包和所述发送时间携带在帧的载荷内向物联网接入点发送。
上述步骤S304的实现方法可以为:
物联网中继器将加密处理后的数据包携带在帧的载荷内,然后将发送时间也携带在载荷内,携带发送时间的目的是为了方便后续的设备获知其选定的加密单元,因为对于设备来说,发送时间是随时变化的,如果不将发送时间携带在该帧内传输,那么对于后续的设备均无法通过方式来获知其采用的何种加密单元,导致无法进行解密。
依据如图3提供的方法,物联网终端将数据包发送至物联网中继器以后,物联网中继器依据工作时段物联网终端的工作时段查询出该工作时段对应的加密单元,通过该加密单元对数据进行加密,对于物联网来说,物联网终端无需对加密进行配置,所有的加密设置均在物联网中继器,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,由于其一个物联网中继器下面可以连接众多的物联网终端,仅仅对物联网中继器配置也可以降低物联网整体的成本,另外,对于物联网中继器来说其计算的能力一般强于物联网终端,因此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中继器数据的分时段加密方法,
该方法在如图4所示的网络构架下实现,如图4所示,一个物联网中继器下可以连接多个物联网终端,该物联网中继器具体可以为开通热点的手机、提供无线连接的个人电脑等设备,该方法如图6所示,包括如下步骤:
步骤S601、物联网终端向物联网中继器发送数据包;
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中物联网终端向物联网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,这里的物联网以及物联网中继器仅仅只是针对无线物联网中继器,因为对于物联网来说,其接入的设备数量众多,对于物联网中继器来说,如果通过有线连接,首先物联网中继器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物联网中继器之间的连接仅限无线连接。
步骤S602、物联网中继器提取该数据包的发送时间,依据该发送时间确定该工作时段物联网终端的工作时段,依据该工作时段在预先配置的工作时段与加密单元映射表中查询出该工作时段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。
上述步骤中的工作时段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物联网中继器的硬件加密单元,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物联网中继器内的软件加密单元,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、物联网中继器获取所述物联网终端发送数据包的信号调制方式,依据所述信号调制方式确定秘钥,调用所述第一加密单元采用所述秘钥对所述数据包进行加密处理。
可选的,上述步骤S603的实现方式具体可以为:
物联网中继器获取该物联网终端发送数据包的信号调制方式,从调制方式与秘钥映射表中查询出该信号调制方式对应的秘钥,调用所述第一加密单元采用所述秘钥对所述数据包进行加密处理。
具体实现例如:如获取的调制方式为二进制相移键控(英文:Binary Phase Shift Keying,BPSK),则采用第一秘钥,如获取的调制方式为正交相移键控(Quadrature Phase Shift Keying,QPSK),则采用第二秘钥。这里采用信号的调制方式的目的在于,因为对于中继器来说,其信号的调制方式是不变的,这样对于后续的设备是能够获取物联网终端信号发送的调制方式的,所以能够通过调制方式的不同来选择不同的秘钥,从而进一步提高安全性。
可选的,上述步骤S603的实现方法具体可以为:
如解析所述数据包得到所述数据包的信号调制方式为正交相移键控QPSK,则获取所述QPSK中具有能量的相位编号,将该相位编号按顺序排序得到的值作为所述秘钥。上述具有能量的相位编号指的是QPSK子载波的具有能量,即该子载波传递数字1,其对应的相位编号具体可以为,其相位的排号,例如第一相位排号为1,第二相位排号为2,第15相位的排号为15,采用此
方式得到秘钥增加秘钥被破译的难度,进一步提高安全性。
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,则物联网中继器调用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,则物联网中继器调用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,则物联网中继器调用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:
物联网中继器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、物联网中继器将加密处理后的数据包和所述发送时间携带在帧的载荷内向物联网接入点发送。
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与物联网中继器连接,那么物联网中继器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,物联网中继器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与物联网中继器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。
本发明采用的技术方案具有安全性高的优点。
可选的,上述方法在步骤S604之后还可以包括:
所述物联网接入点调用所述第一加密单元加密不成功,所述物联网接入点调用第一加密单元的备用加密单元对所述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。
