具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请提供的车辆解锁方法，可应用在如图1的应用环境中，其中，终端设备通过网络与车辆中控端进行通信。通过在对车辆进行智能解锁的过程中使用由RSA算法生成的保密密钥和公开密钥，对进行开锁的关键数据即所述解锁密文进行加密，进一步地，通过预设的开锁规则对所述解锁密文进行判定，在所述解锁密文符合开锁条件时，对车辆进行解锁。其中，终端设备包括但不限于各种个人计算机、笔记本电脑、智能手机、平板电脑和便携式可穿戴设备。车辆中控端安装在所述车辆中，可以用独立的服务器或者是多个服务器组成的服务器集群来实现。
在一实施例中，如图2所示，提供一种车辆解锁方法，以该方法应用在图1中的车辆中控端为例进行说明，所述车辆解锁方法包括在车辆中控端执行的如下步骤：
S10，接收终端设备发送的包含唯一标识的无线连接请求，并根据所述唯一标识与所述终端设备建立无线连接。
其中，所述终端设备包括但不限于手机、智能手表、具有通讯功能(蓝牙功能)的钥匙环等移动终端，还包括电脑等终端设备。所述唯一标识是用于区分不同的终端设备的具有唯一性的标识。
所述连接请求可以由用户通过点击预设的按钮发送至车辆中控端，还可以在进入到接收器的一定范围内，自动发送至车辆中控端。比如，当用户想要对车辆进行解锁时，通过点击其携带的终端设备的预设按钮发送所述连接请求至车辆中控端，亦或者，当所述用户进入到该车辆的一定范围内，其携带的所述终端设备检测到后，自动将所述连接请求发送至车辆中控端。
可理解地，车辆中控端接收到所述连接请求后，即与所述终端设备建立无线连接，在一实施例中，所述连接请求是通过蓝牙发送至车辆中控端，而所述车辆中控端接收请求后，即通过蓝牙与所述终端设备建立无线连接。在另一实施例中，所述车辆中控端与所述终端设备建立无线连接还可以通过无线网络技术(如WiFi)与所述终端设备建立无线连接。与所述终端设备建立无线连接，以供在后续步骤中接收所述终端设备发送的车辆解锁指令，以便于对车辆进行解锁。
S20，接收所述终端设备发送的车辆解锁指令，所述车辆解锁指令包含在所述终端设备经过第一保密密钥加密之后的解锁密文，所述第一保密密钥是根据RSA算法生成的密钥。
其中，所述车辆解锁指令是用于对车辆进行解锁的指令，车辆中控端接收到所述车辆解锁指令后，即开启对车辆的解锁流程。所述解锁密文是用于对车辆进行解锁的密文，可以是一串字符、一个词语、或一句话等。所述解锁密文可以在发送所述车辆解锁指令时生成，并通过所述第一保密密钥进行加密，也可以经过所述RSA算法的第一保密密钥加密后预先存储在所述终端设备中。
所述RSA算法是一种非对称加密算法，即根据所述RSA算法生成的用于对信息或数据进行加密的密钥，与根据所述RSA算法生成的用于对信息或数据进行解密的密钥，是非对称的。举例说明，根据所述RSA算法同时生成一对密钥，分别为第一保密密钥和第一公开密钥，当使用所述第一保密密钥对信息或数据进行加密时，不能通过所述第一保密密钥对该信息或该数据进行解密，而须使用与所述第一保密密钥不同且不对称(该不对称是指不能根据已知的所述第一保密密钥通过已知的方法推导出所述第一公开密钥)的第一公开密钥，方能对经过所述第一保密密钥加密的信息或数据进行解密。
在使用所述RSA算法对信息或数据进行加密时，首先根据所述RSA算法同时生成一对密钥，其中之一是保密的，不公开的，也即只有用户或用户预设的人或设备才能保存或知晓的密钥，该密钥即为保密密钥(在本实施例中，即为所述第一保密密钥)；而另一个密钥则是公开的、非保密的，任何人或设备都可以获知或获取的密钥，该秘钥为公开密钥(在本实施例中，即为所述第一公开密钥)。可理解地，所述第一保密密钥和所述第一公开密钥互为一对非对称密钥，即当使用所述第一保密密钥对信息或数据进行加密时，则使用所述第一公开密钥即可对加密后的该信息或该数据进行解密；反之，当使用所述第一公开密钥对信息或数据进行加密时，则使用所述第一保密密钥即可对加密后的该信息或该数据进行解密。必须说明的是，所述第一保密密钥预先在所述车辆中控端中根据所述RSA算法生成后，即发送并存储至由用户支配的终端设备。
在本实施例中，设定使用所述第一保密密钥对所述解锁密文进行加密，可理解地，所述第一保密密钥通常存储在由用户所支配的所述终端设备中，当用户需要对车辆进行解锁时，即通过已与车辆建立了无线连接的所述终端设备使用所述第一保密密钥加密所述解锁密文，或直接调取预先存储在所述终端设备上的已经过所述第一保密密钥加密的所述解锁密文，将加密后的解锁密文发送至所述车辆中控端，可理解地，车辆中控端接收所述加密后的解锁密文，以供在后续步骤中对所述解锁密文进行解密，进而判定所述提起车辆解锁请求的用户是否符合开锁的条件。
S30，使用根据所述RSA算法生成的第一公开密钥对所述解锁密文进行解密，并获取解密后的所述解锁密文。
如上所述，所述第一公开密钥是根据所述RSA算法与所述第一保密密钥同时生成的一个公开的、非保密的密钥，所述第一公开密钥与所述第一保密密钥互为一对非对称密钥。所述第一公开密钥在根据所述RSA算法生成后，存储在车辆中控端的车辆数据库中。
具体地，当车辆中控端接收到终端设备发送的解密密文后，即从车辆数据库中调取所述第一公开密钥，然后，通过所述第一公开密钥对接收到的所述解锁密文进行解密，生成解密后的所述解锁密文，接着，获取所述解锁密文，以供在 步骤S40中，检测解密后的所述解锁密文是否符合预设的开锁条件。
S40，根据预设的开锁规则，检测解密后的所述解锁密文是否符合开锁条件。
其中，所述开锁规则可以根据需求预先设定。
在一实施例中，所述开锁规则可以设定为当所述解锁密文的内容与预设的开锁密文的内容一致时，所述解锁密文即符合开锁条件。如上所述，所述解锁密文亦可以是用户根据需求预先设定的，可以是一串字符、一个词语或一句话等，这里以所述解锁密文为一个词语对本实施例进行说明：比如预设的开锁密文为“你好”，此时，检测解密后的所述解锁密文的内容是否与所述开锁密文一致，也即，检测所述解锁密文的内容是否为“你好”，当结果为是时，代表所述解锁密文符合所述开锁条件，此时，进入步骤S50，对车辆进行解锁；当结果为否时，代表所述解锁密文不符合开锁条件，此时，确认所述解锁密文不符合开锁条件，将此次的车辆解锁请求记录为请求失败，并将所述车辆解锁请求的请求失败次数加一，以便于在一些实施例中，根据所述请求失败的次数，对下一次的车辆解锁请求进行预设的限定。
在另一实施例中，所述开锁规则包含至少一个终端设备的第一唯一标识，即预先将所有能进行开锁的终端设备的唯一标识存储在所述开锁规则中；所述解锁密文的内容为当前用户所使用的终端设备的第二唯一标识，也即发起车辆解锁指令的终端设备的唯一标识，在该实施例中，检测所述开锁规则中的所有第一唯一标识中是否存在与所述解锁密文中的第二唯一标识一致的标识，也即，将所述第二唯一标识与所述所有所述第一唯一标识分别进行比对，当检测到所有所述第一唯一标识中存在与所述第二唯一标识相一致的唯一标识时，代表所述第二唯一标识对应的终端设备为预先设定的可以对该车辆进行开锁的终端设备，此时，确认所述解锁密文符合开锁条件；而当检测到所有所述第一唯一标识中不存在与所述第二唯一标识相一致的唯一标识时，代表所述第二唯一标识对应的终端设备并非预先存在所述开锁规则中的终端设备，此时，将此次的车辆解锁请求记录为请求失败，并将所述车辆解锁请求的请求失败次数加一。
S50，当所述解锁密文符合所述开锁条件时，对车辆进行解锁。
当所述解锁密文符合所述开锁条件时，代表发起车辆开锁指令操作的用户拥有 开锁资格，此时，根据所述车辆解锁指令，对所述车辆进行解锁。
本实施例通过在对车辆进行智能解锁的过程中使用由RSA算法生成的保密密钥和公开密钥，对进行开锁的关键数据即所述解锁密文进行加密，在对车辆进行快速智能解锁的同时，大大提升了因为智能解锁的安全性，以防止出现被他人破解车辆解锁程序而造成用户财产损失，增强用户体验。
在一实施例中，所述开锁规则中包含预设的开锁时间长度，以及预设的开锁密文，所述解锁密文包含解锁密文内容以及与所述终端设备生成所述解锁密文的时间点对应的时间戳；如图3所示，所述步骤S40包括：
S401，检测所述解锁密文内容与所述开锁密文是否一致。
所述解锁密文中包含解锁密文内容，所述解锁密文内容可以是一串字符、一句话或一个词语等，用于与所述开锁规则中的开锁密文进行比对，在本实施例中，检测所述解锁密文内容与所述开锁规则中预设的开锁密文是否一致，当所述解锁密文内容与所述开锁密文一致时，代表所述解锁密文即可能符合所述开锁条件，此时，进入步骤S402，根据所述时间戳获取所述终端设备生成所述解锁密文的时间点，以便进一步验证所述解锁密文是否符合开锁条件。当所述解锁密文内容与所述开锁密文内容不一致时，确认所述解锁密文不符合所述开锁条件，并将此次的车辆解锁请求记录为请求失败，并将所述车辆解锁请求的请求失败次数加一。
S402，当所述解锁密文内容与所述开锁密文一致时，根据所述时间戳获取所述终端设备生成所述解锁密文的时间点。
所述解锁密文还包含在所述终端设备生成所述解锁密文的时间点对应的时间戳，所述时间戳为一个能表示一份数据在某个特定时间之前已经存在的、完整的、可验证的字符序列，所述时间戳唯一地标识某一刻的时间，具体地，所述时间戳是使用数据签名技术所产生的数据，签名的对象包括了原始文件(数据)信息、签名参数、签名时间等信息，所述时间戳可以为所述解锁密文提供一种电子证据，证明所述解锁密文生成的时间，且证明的真实性非常高，因为时间戳在已知的技术中无法被篡改。必须说明的是，在本实施例中，首先设定解锁密文的发送规则，并预先存储至所述终端设备中，该规则为当用户需要发送车 辆解锁指令，并已经点击预设的按钮进行了发送车辆解锁指令的操作时，才生成所述解密密文内容，且在生成所述解密密文内容后，以最快的速度为生成的所述解密密文内容生成对应的时间戳，同时，使用所述第一保密密钥对所述解密密文内容和生成的时间戳进行加密，生成加密后的解密密文，可理解地，生成的该时间戳即可近似的标识所述解密密文生成的时间点。在本实施例中，获取所述终端设备生成所述解锁密文的时间点，以供在步骤S403中进一步判定所述解锁密文是否符合所述开锁条件。
S403，检测生成所述解锁密文的时间点与接收到所述解锁密文的时间点之间的时间长度是否小于所述开锁时间长度，当生成所述解锁密文的时间点与接收到所述解锁密文的时间点之间的时间长度小于所述开锁时间长度时，确认所述解锁密文符合所述开锁条件。
其中，所述开锁时间长度可以根据需求预先设定。作为优选，所述开锁时间长度为2秒。
可理解地，在本实施例中，预先设定了解锁密文的发送规则，即当用户发起车辆解锁指令操作的时候，方才生成所述解锁密文，并对所述解锁密文加盖时间戳，则若所述终端设备生成所述解锁密文的时间点与车辆中控端接收到所述解锁密文的时间点之间的时间长度过大，也即所述解锁密文在生成了比较久的时间之后，才发送到所述车辆中控端，代表有可能是所述解锁密文或所述第一保密密钥被他人所破解或获知，并预先存储下来，在对车辆进行开锁的时候发送至车辆中控端。
因此，检测所述终端设备生成所述解锁密文的时间点，与所述车辆中控端接收到所述解锁密文的时间点之间的时间长度是否小于所述开锁时间长度，当生成所述解锁密文的时间点与接收到所述解锁密文的时间点之间的时间长度大于或等于所述开锁时间长度，证明所述解锁密文不符合所述开锁条件，即发起车辆解锁指令的用户可能不具备开锁的资格，此时，确认所述解锁密文不符合所述开锁条件，并记录此次的车辆解锁请求不能通过，即车辆解锁请求不能通过的次数加一；反之，当生成所述解锁密文的时间点与接收到所述解锁密文的时间点之间的时间长度小于所述开锁时间长度时，代表所述解锁密文是按照预设的 发送规则进行发送的，也即所述解锁密文符合所述开锁条件，此时，确认所述解锁密文符合所述开锁条件，以便在后续步骤中对所述车辆进行解锁。
本实施例通过在所述解锁密文生成时对其加盖时间戳，保证检测到的生成所述解锁密文的时间点与接收到所述解锁密文的时间点是真实有效、没有被篡改的，并对生成所述解锁密文的时间点与接收到所述解锁密文的时间点之间的时间长度与所述开锁时间长度进行比较，进一步判定所述解锁密文是否符合开锁条件，大大提升了车辆开锁时的安全性，增强用户体验。
在一实施例中，如图4所示，所述步骤S40之后，还包括：
S60，当所述解锁密文不符合所述开锁条件时，将本次所述车辆解锁请求记录为请求失败，并将所述车辆解锁请求的请求失败次数加一。
当所述解锁密文不符合所述开锁条件时，代表发起所述车辆解锁指令操作，也即发起此次的车辆解锁请求的用户不具有开锁资格，此时，将此次的车辆解锁请求记录为请求失败，并将所述车辆解锁请求的请求失败次数加一。必须说明的是，每一次记录的车辆解锁请求的请求失败的次数将会累加，但是当车辆中控端有通过所述车辆解锁请求时，也即对车辆进行过解锁时，此前所记录的车辆解锁请求的请求失败的次数将会清零。举例说明，如果有连续三次车辆解锁请求不能通过，则此时记录并累加的车辆解锁请求的请求失败次数为3，此时，若下一次的车辆解锁请求被车辆中控端所通过，则此前记录的车辆解锁请求的请求失败次数为3的结果清零，即车辆解锁请求的请求失败次数为0，并重新开始记录。
S70，当所述车辆解锁请求的请求失败次数大于预设的锁定阈值时，对所述车辆进行锁定。
在一实施例中，所述车辆解锁请求的请求失败次数还包括在所述步骤S401中所记录的请求失败次数。
所述锁定阈值可以根据需求预先设定，作为优选，所述锁定阈值为5。所述对车辆进行锁定，包括：在预设的时间段内，不再接收车辆解锁指令，也即不对车辆进行解锁，并将对所述车辆进行锁定的情况发送给预设的管理方，提醒所述管理方有人恶意开锁或者正在对所述车辆中控端进行攻击(破解)。
当所述车辆解锁请求不能通过的次数大于所述锁定阈值时，代表所述车辆可能遇到有人恶意开锁或对开锁系统进行攻击(破解)的情形，此时，对所述车辆进行锁定，防止所述车辆的解锁系统被人所攻击(破解)，提升车辆解锁的安全性，增强用户体验。
在一实施例中，如图5所示，提供一种车辆解锁方法，以该方法应用在图1中的终端设备为例进行说明，所述车辆解锁方法包括在终端设备执行的如下步骤：
S80，将包含唯一标识的无线连接请求发送至终端设备，并通过所述唯一标识与车辆中控端建立无线连接。
如上述，所述唯一标识是用于区分不同的终端设备的具有唯一性的标识。当持有所述终端设备的用户需要对车辆进行解锁时，即通过所述终端设备发送所述连接请求至所述车辆中控端，亦或者，当所述用户进入到该车辆的一定范围内，其携带的所述终端设备检测到后，自动将所述连接请求发送至车辆中控端；所述车辆中控端接收到所述连接请求后，即与终端设备进行无线连接，所述无线连接的建立通过无线网络技术，比如WIFI、蓝牙等，与所述车辆中控端建立无线连接，以便于在后续步骤中发送车辆解锁指令至所述车辆中控端。
S90，获取第一保密密钥和解锁密文，并通过所述第一保密密钥加密所述解锁密文。
首先获取所述第一保密密钥，在一实施例中，所述第一保密密钥可以是在所述车辆中控端中根据RSA算法预先生成，并发送存储至终端设备车辆中控端的终端数据库中，获取时即从终端设备的终端数据库中调取即可，获取所述解锁密文包括：按照预先设定的密文规则生成解锁密文，或是所述解锁密文预先已经设定好并存储在终端设备的终端数据库中，此时直接从该终端数据库中调取所述解锁密文。进一步地，通过所述第一保密密钥对所述解锁密文进行加密，以供在后续步骤中将所述解锁密文发送至所述车辆中控端进行后续的解锁流程。
S100，将包含所述解锁密文的车辆解锁指令发送至所述车辆中控端，以供所述车辆中控端使用第一公开密钥对加密后的所述解锁密文进行解密之后，在所述解锁密文符合开锁条件时对车辆进行解锁。
将包含加密后的所述解锁密文的车辆解锁指令发送至所述车辆中控端，进行后 续的解锁流程，所述解锁流程可以参照步骤S30至步骤50所述，或S30至S70所述，在此不再赘述。
在一实施例中，如图6所示，所述步骤S90包括：
S901，获取经过第二公开密钥加密的第一保密密钥，并获取与所述第二公开密钥对应的第二保密密钥。
其中，所述第二公开密钥和所述第二保密密钥是由RSA算法生成的一对非对称密钥，所述第二公开密钥与所述第一公开密钥不一致(即二者为两个不同的密钥)，所述第二保密密钥与所述第一保密密钥不一致(即二者为两个不同的密钥)，所述第二公开密钥用于加密所述第一保密密钥，而所述第二保密密钥用于加密经过所述第二公开密钥加密后的第一保密密钥。所述第二公开密钥和所述第二保密密钥预先生成并存储在所述终端设备终端数据库中。
