具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
如图1所示的是现有技术中基于动态密码的智能门锁系统，其实现过程需要依靠智能门锁中的无线通信模块通过网关和云服务器进行密码的请求和密码的发送，其所造成的技术问题或者缺陷，一是智能门锁耗能的增加，无线通信模块需要长时间的，大量的电量供应；二是一旦其断电或者网关停电、家里网络故障，就无法远程下达密码到交互终端。
基于上述技术问题，本申请提供了一种基于智能门锁系统的离线验证码的生成方法，可在智能门锁不具备通信功能的情况下，远程获取有效的临时开门密码，或者获取密码生成指令，例如可在门锁面板中输入密码生成指令来启用密码。该方法解决了现有的智能门锁在网关断电、断网、无线故障或者不安装网关的情况下，无法下发密码开门的问题，同时，该方法无需在锁内部设置和网关以及云服务器进行交互的通信模块，大大减少了自身耗能。
参考图2，为本申请实施例提供的一种基于智能门锁系统的离线验证码的生成方法流程图，该方法应用于移动终端，具体包括：
S201：移动终端响应于开锁事件记录该开锁事件的触发时间。
开锁事件可以包括但不限于用户的如下操作，如点击确认操作、滑动操作、录入密码或认证信息进行登录的操作等。当移动终端检测到任一种开锁事件后，在后台记录该开锁事件的触发时间，该触发时间可以用于获取智能门锁的验证码。
本申请实施例中的移动终端可以是手机，IPAD，笔记本电脑，智能手表或智能手环等智能移动设备。一种实施方式中，当用户通过智能手机或IPAD或移动型笔记本电脑等，点击屏幕上的开锁确认键，或者滑动开锁开关，或者通过上述移动终端的APP或web页面录入密码或认证信息等进行登录操作时，即可认为是用户触发开锁事件。另外，用户也可通过智能手表，智能手环等触发开锁事件，并在上述移动终端的后台记录该开锁事件的触发时间。
S202：响应于开锁事件，移动终端向云服务器发送带有开锁验证信息的请求，所述带有开锁验证信息的请求用于请求云服务器返回智能门锁的验证码；所述开锁验证信息包括该智能门锁的私钥种子和所述触发时间。
其中，云服务器中设有私钥种子数据库，该私钥种子数据库用于存储各个智能门锁的私钥种子。其中，每个智能门锁的私钥种子可以是唯一不重复的密钥，每个智能门锁具有唯一的私钥种子，且各个智能门锁与私钥种子的对应关系预先存储于私钥种子数据库中。另外，当移动终端与智能门锁绑定后，该移动终端也存储有该智能门锁的私钥种子，也就是说，该移动终端与该智能门锁的私钥种子具有对应关系。
当移动终端检测到开锁事件后，还可以向云服务器发送带有开锁验证信息的请求，用于请求云服务器返回智能门锁的验证码。其中，该开锁验证信息包括智能门锁的私钥种子和该开锁时间的触发时间。私钥种子与智能门锁具有唯一的对应关系，通常私钥种子可以在智能门锁出厂时生成并同时写入该智能门锁以及存入云服务器中。为了确保每把智能门锁的动态密码安全，每一把智能门锁的私钥种子都是不同的，即使智能门锁的加密算法泄露，或者黑客获取到某把智能门锁的私钥种子，也不会威胁到其他用户的智能门锁安全。
S203：移动终端接收云服务器根据私钥种子和触发时间生成的智能门锁的验证码，以便用于开启该智能门锁。
云服务器在接收到来自移动终端的私钥种子和触发时间后，根据私钥种子和触发时间生成智能门锁的验证码，云服务器将该验证码返回至移动终端后，用户可以利用移动终端上显示的该验证码开启智能门锁。
本申请实施例提供的基于智能门锁系统的离线验证码的生成方法中，移动终端响应于开锁事件记录该开锁事件的触发时间，以及向云服务器发送携带有智能门锁的私钥种子和触发时间的请求，以便请求云服务器返回智能门锁的验证码，智能终端接收到该验证码后，用于开启智能门锁。可见，本申请实施例在智能门锁离线的情况下从云服务器获取验证码，完成智能门锁的开启，该方式解决了现有的智能门锁在网关断电、断网、无线故障或者不安装网关的情况下，无法下发密码开门的问题，同时，该方法无需在锁内部设置和网关以及云服务器进行交互的通信模块，大大减少了自身耗能。
另外，本申请的智能门锁系统只需要在每个时间周期安装预先设置的验证码生成方法，生成验证码并存储在所内部，无需在锁内部设置和网关以及云服务器进行交互的通信模块，大大减少了自身耗能和缩小了自身体积，因此，可以使智能门锁系统不受到外界网络环境的制约，可以以离线验证码的方式，实现其开启操作，实现了一种安全，可靠，不受外界网络环境影响的，自身不包括通信模块的智能门锁系统。
与上述实施例相对应的，本申请实施例还提供了一种基于智能门锁系统的离线验证码的生成方法，该方法应用于云服务器，参考图3，为本申请实施例提供的另一种基于智能门锁系统的离线验证码的生成方法流程图，具体包括：
S301：云服务器接收来自移动终端的带有开锁验证信息的请求；其中，所述开锁验证信息包括智能门锁的私钥种子和所述移动终端响应于所述开锁事件记录的触发时间。
本申请实施例中的S301可参照上述实施例中的S201和S202进行理解，在此不再赘述。
S302：云服务器对所述私钥种子匹配验证成功后，生成所述智能门锁的验证码，并将所述智能门锁的验证码返回至所述移动终端，以便用于开启所述智能门锁。
本申请实施例中，云服务器接收到带有开锁验证信息的请求后，首先获取请求中的私钥种子，并对该私钥种子进行匹配验证。一种实现方式中，云 服务器将获取到的私钥种子与私钥种子数据库中已存储的各个智能门锁的私钥种子进行比对，如果比对成功，即私钥种子数据库中已存储有获取到的私钥种子，则确定对该获取到的私钥种子匹配验证成功；否则，认为该私钥种子匹配验证失败。
当云服务器对获取到的私钥种子匹配验证成功后，生成智能门锁的验证码，并将生成的智能门锁的验证码返回至移动终端，以便用户利用该验证码开启智能门锁。
具体的，本申请实施例中云服务器生成智能门锁的验证码的方式可以包括以下两种方式，以下分别进行详细介绍。
其中，一种实现方式中，智能门锁的验证码可以为动态密码，具体的，云服务器根据匹配验证成功的私钥种子及触发时间生成预设时间周期内的动态密码。
云服务器可以通过预设第一验证码生成算法生成智能门锁的验证码，具体的，第一验证码生成算法可以包括但不限于各种类型的哈希算法，云服务器接收到的私钥种子和触发时间可以作为该第一验证码生成算法的输入参数，从而生成当前时间智能门锁的验证码，该验证码为动态密码，也就是说，不同的时间周期智能门锁的验证码不同。
具体的，云服务器根据触发时间可以确定生成的智能门锁的验证码属于哪一时间周期内的动态密码。一种实现方式中，云服务器将触发时间与私钥种子通过预设第一验证码生成算法转换为数位密码，例如六位密码。
对应的，智能门锁通过相同的验证码生成算法实现不同时间周期内的验证码的生成。具体的，智能门锁通过第一验证码生成算法在每个时间周期开始时，计算出当前时间周期内的动态密码并进行存储。该当前时间周期内的动态密码可以为根据每个时间周期的起始时间与私钥种子的结合而输出的智能门锁的验证码。其中，作为第一验证码生成算法的输入参数的时间周期的起始时间可以为开始为该时间周期内每个整点的起始时间，也可以为该时间周期内每个半点的起始时间。具体的，智能门锁与云服务器采用相同的验证码生成算法，生成相同的每个时间周期对应的验证码。当智能门锁接收到任 一验证码的输入后，将该验证码与已存储的当前时间周期内的验证码进行比对，如果相同，则开启智能门锁，否则开启智能门锁失败。
另外，为了排除门锁本地时间与云服务器时间的偏差，可以将时间精确到小时级别，即时间周期可以为每个小时整点。
另外，为了增加动态密码在时间跨度的可用性，比如，在2点59分生成的动态密码，在1分钟后可能就会过期，这样该密码的可用性大大降低。为此，本申请实施例增加了缓冲的机制，即在智能门锁每个整点计算出当前整点动态密码的同时，会保留前一个整点的动态密码依然有效，也就是任意时刻保证当前与前一整点的动态密码有效。这样能够保证从云服务获取的动态密码的有效期是最少一个小时，最长2小时，从而避免动态密码失效的情况发生。
另一种实现方式中，云服务器生成密码生成指令，用于使智能门锁的验证码在智能门锁中生效，从而用户可以通过验证码开启智能门锁。
其中，云服务器生成的密码生成指令可以由数字和#*构成，云服务器生成密码生成指令的输入参数可以包括起始码、命令码、类型码、有效期码、密码、密码ID、校验码、时间因子和私钥种子等。
其中，校验码用于验证指令的合法性和完整性，可以根据对安全的需要，采用不同位数，位数越长越安全，同时，生成的密码生成指令的位数会加长，用户输入难度会增加。针对不同的使用场景，面对不同的用户人群，可以采用不同的校验码位数。
私钥种子和上述动态密码的私钥种子类似，是在智能门锁出厂时生成并同时写入智能门锁以及存入云服务中，每一个智能门锁的私钥种子都是不同的，确保每把智能门锁的密码生成指令的生成安全。
密码ID用于密码的后续管理，在云服务器中密码ID可以和用户命名的特定名称做对应，这样后续对智能门锁的密码列表进行管理时，操作对象将是密码ID，密码ID在生成密码生成指令时是可选的输入参数。
另外，通过命令码可以实现密码的增、删、改、查等操作，当然，不同的命令码后面的指令码段组合可以不同。对于其他输入参数在此不再进行详细介绍。
密码生成指令的生成算法的输入参数可以包含上述各个输入参数，以及私钥种子和触发时间。例如：密码生成指令＝预设私有算法((起始码+命令码+类型码+有效期码+密码+密码ID)，私钥种子，触发时间)。
其中，触发时间可以精确到天级别，可以用当天整0点时间，所以，密码生成指令的有效期是当天输入有效。另外，可以根据需求通过对时间向前兼容的方式来延长密码生成指令的有效期，比如，同时用当前0点与昨天0点验证校验码，则将密码生成指令的有效期延长到最长2天。
若结合上述动态密码的生成方式，本申请可以将密码生成指令中去除密码段，而用2位数字来指定使用哪个小时整点的动态密码。按照常规，2位数可以指定100个小时，也就是可以指定某个小时整点为起始，往后的100个小时的动态密码的一个，作为这次密码生成指令的生效密码。该方法可以把密码生成指令中的密码段缩减到2位，减少整个密码生成指令的位数。
为了避免与动态密码重复，这里的动态密码生成机制保留，但是，算法里增加变量因子，可以保证与上述方法生成的动态密码不重复。
云服务器在生成密码生成指令后，将该密码生成指令返回至移动终端，用户利用移动终端上显示的密码生成指令使得智能门锁的密码生效，例如使得利用第一验证码生成算法生成的动态密码在智能门锁上生效。具体的，智能门锁接收到密码生成指令后，对该指令进行解析，从而生成生效的验证码，在用户输入正确的验证码后，开启智能门锁。
