板卡标识可以认为是标识电子设备板卡的信息。密钥信息可以认为是烧录密钥所需信息。此处不对密钥信息进行限定，只要能够基于密钥信息完成待烧录密钥烧录即可。
本实施例不对获取手段进行限定，配置信息可以由远端设备主动下发，电子设备板卡直接获取即可；配置信息也可以是电子设备板卡发送请求信息后，触发远端设备下发，电子设备板卡在发送请求信息后，获取对应请求信息的配置信息。
发送至电子设备板卡的配置信息可以由映射策略确定。映射策略中可以包括有多组板卡标识和密钥信息的映射关系。发送至电子设备板卡的配置信息可以基于板卡标识确定，向与板卡标识匹配的电子设备板卡发送对应的密钥信息。此处不对发送时机进行限定，如在获取到电子设备板卡的请求信息后发送；又如在设定时间发送；再如检测到更新请求后发送。
其中，请求信息的触发不作限定，如在电子设备板卡上电时，触发请求信息，或在预设时间触发请求信息。在映射策略变更时可以触发更新请求。映射策略变更可以认为是板卡标识和密钥信息的映射关系变更。触发的更新请求可以用于映射策略变更的板卡标识所对应的电子设备板卡发送配置信息，以完成密钥烧录。
在一个实施例中，在远端设备确定某一板卡标识对应的电子设备板卡的某一密钥烧录错误时，远端设备可以更新该板卡标识的映射策略，然后向该板卡标识对应的电子设备板卡发送配置信息，该配置信息可以包括有变更后的密钥信息，以重新烧录之前烧录错误的密钥。

在一个实施例中，在电子设备板卡检测到未烧录某一密钥时，可以向远端设备发送请求信息，远端设备基于请求信息发送对应的配置信息，以实现待烧录密钥的烧录。本实施例中某一密钥可以认为是待烧录密钥。
在一个实施例中，若使用电子设备板卡的用户有增加新的密钥的需求，则远端设备可以更新映射策略，以基于更新后的映射策略完成待烧录密钥的烧录。
S120、根据所述配置信息对所述待烧录密钥进行校验。
获取配置信息后，本步骤可以基于配置信息对待烧录密钥进行校验，以验证待烧录密钥是否正确且完整。
在一个实施例中，本步骤可以实现待烧录密钥的完整性的校验。如校验解密后密钥(KEY)，即待烧录密钥的完整性，校验KEY(即从远端设备获取的密钥，该密钥可以为经过加密后的待烧录密钥)的完整性。
此处不对如何进行完整性校验进行限定，如基于校验码进行校验。

基于加密后的待烧录密钥的校验码对加密后的待烧录密钥进行校验，基于待烧录密钥的校验码对解密后的待烧录密钥进行校验。
S130、基于校验结果烧录所述待烧录密钥。
校验结果可以指示校验通过和校验失败，在校验通过时，可以直接执行烧录操作；在校验结果指示校验失败时，可以结束本次烧录继续监测是否再次获取到配置信息，以继续执行校验操作，直至完成烧录。
在本实施例中，本实施例还可以包括向远端设备传输电子设备板卡的烧录结果、校验结果等，以供远端设备备份。
本申请实施例提供的一种密钥烧录方法，首先获取待烧录密钥的配置信息，所述配置信息由远端设备根据映射策略确定，所述映射策略包括板卡标识和密钥信息的映射关系；然后根据所述配置信息对所述待烧录密钥进行校验；最后基于校验结果烧录所述待烧录密钥。利用上述技术方案，在出现密钥烧录错误或未烧录时，无需返厂或现场维修，可直接获取远端设备下发的配置信息，基于配置信息完成密钥烧录，从而有效降低了密钥未烧录或烧录错误所增加的维修成本。
在上述实施例的基础上，提出了上述实施例的变型实施例，在此需要说明的是，为了使描述简要，在变型实施例中仅描述与上述实施例的不同之处。
在一个实施例中，所述配置信息在获取到更新请求后触发发送，所述更新请求在所述映射策略变更的情况下触发。

下载状态指示信息可以认为是指示是否可以下载的信息。需要注意的是，即使远端设备上布置了待烧录密钥的映射策略，但是由于某些原因(此处不作限定，如密钥修复)，待烧录密钥不可下载。故，本实施例中的密钥信息可以包括下载状态指示信息以指示待烧录密钥是否可以下载。若待烧录密钥不可以下载，则结束操作，继续监测是否获取到配置信息。
类型信息可以认为是标识密钥类型的信息。下载信息可以认为是用于下载密钥的信息。校验码可以认为是用于进行校验的信息。附加信息不作限定可以基于实际需求设定。

在一个实施例中，在根据所述配置信息对所述待烧录密钥进行校验之前，还包括：
在所述下载状态指示信息指示可下载时，执行校验操作；
在所述下载状态指示信息指示不可下载时，结束操作，并继续监测是否获取到新的配置信息。
新的配置信息可以是远端设备重新发送的待烧录密钥的配置信息，也可以为其余密钥的配置信息。
在一个实施例中，所述基于校验结果烧录所述待烧录密钥，包括：
若校验结果指示校验通过，则烧录所述待烧录密钥；

基于所述烧录状态，确定待烧录密钥；

本实施例尚未详尽的内容请参考前述实施例。
如图2所示，本申请另一实施例提供的一种密钥烧录方法，包括如下步骤：
S210、确定预存储的密钥池中密钥的烧录状态。
密钥池可以认为是电子设备板卡所能够烧录的所有密钥形成的集合。密钥池中可以包括电子设备板卡的用户未购买或不需要烧录的密钥。
在进行密钥烧录前，本步骤可以遍历密钥池中所有密钥，确定密钥的烧录状态。烧录状态可以为表征对应密钥是否烧录的状态。此处不对如何确定烧录状态进行限定。

本申请实施例提供的一种密钥烧录方法，具体包括了触发请求信息的操作。利用该方法，能够有效的基于请求信息请求远端设备远程控制电子设备板卡进行密钥烧录，有效降低了密钥未烧录或烧录错误所增加的维修成本。
以下对本申请进行示例性描述，本申请提供的一种密钥烧录方法可以认为是一种可云端部署策略的远程烧录软件KEY的方法，以电子设备为智能电视为例，现在很多智能电视都需要烧录很多的关键KEY用于支持制定格式的视频资源或者确定唯一性，例如电视序列号，HDCP key，Widevine Key等。这些关键KEY通常会设计存储在一个通过升级、空中下载技术(Over-the-Air Technology，OTA)等常规系统更新方式无法擦除的磁盘分区，以便保持其独有性，但是如果这些KEY在生产过程没有烧录，或者烧录错误，就会导致大批量的返工和现场维修，本方案是基于该场景，设计出远程烧录的方式。
此外，出货的电子设备并非全部都需要远程烧录，需要在云端部署策略，控制哪些电子设备烧录哪些KEY，根据云端部署的策略，可控的远程向设备端烧录KEY。
本申请中主要涉及三端，即客户端、服务端和系统端，其中，客户端主要在应用程序中实现，会预装在系统中；服务端主要由远程后台系统来实现，由服务器做统一调度控制；系统端是系统烧录端接口实现的。
图3为本申请示例实施例提供的一种密钥烧录方法的流程示意图；图4为本申请示例实施例提供的一种密钥烧录方法的时序示意图；参见图3和图4，客户端的功能主要由应用程序实现，会预装到系统，即板卡中。应用程序主要实现如下功能：
1.key的检测，即图3中获取当前制定类型KEY烧录状态，然后确定是否有烧录。其中，当前制定类型KEY可以认为当前板卡已经定制的KEY，在本申请中通过密钥池表征。
2.配置文件解析，配置文件可以认为是服务端返回信息。其中，是否可以下载状态可以认为是下载状态指示信息，用于指示对应KEY是否可以下载，即用于判断是否有KEY。KEY的类型可以用于烧录对应的KEY，不同类型的KEY对应的烧录方式不同，此处不作限定。下载链接可以认为是下载信息，基于下载链接可以下载对应的KEY。此处不对附加信息进行限定，可以根据实际情况设定任一所需信息作为附加信息。需要注意的是，本申请中密钥的英文释义不区分大小写，无论大小写表示的均是密钥。
需要注意的是，服务端可以存储有不同电子设备板卡所对应的密钥，故本实施例可以基于产品序列号(Serial Number，SN)向服务端请求待烧录密钥。协同参数可以认为是协同SN能够标识电子设备板卡的参数。服务端在获取到SN等协同参数后，可以检测是否有对应的 烧录KEY，即待烧录密钥。
3.KEY下载。
4.KEY的完整性(md5)校验，即基于校验码，如基于加密后密钥的md5码校验KEY的完整性，基于密钥的md5码校验烧录KEY的完整性。
5.KEY的解密。
6.KEY的烧录部分完整性校验，即验证烧录KEY的完整性。
7.KEY的烧录。
8.KEY的多种状态反馈。如KEY的烧录结果、KEY的信息等。
9.KEY的析构，如删除烧录KEY过程中产生的临时文件，临时文件包括下载的KEY；又如更新烧录标识。
服务端可由后台实现，由对应的服务器做控制，服务端主要实现如下功能：
1.KEY的唯一性映射绑定：即映射策略，映射策略包括KEY的类型、KEY关联的电子设备板卡、KEY关联的SN。其中，映射策略中的密钥信息可以为KEY的类型，板卡标识可以通过KEY关联的电子设备板卡、KEY关联的SN表征。这部分可以参考CBD后台的配置文件处理。
2.KEY的部署，如制定映射策略。
3.针对客户端的请求进行响应格式制定：1.检测响应；2.下载响应；3.异常预警响应，其中，检测响应可以认为是通过SN等系统参数检测是否有对应的待烧录密钥的响应；下载响应可以认为是客户端基于下载链接进行待烧录密钥下载的响应；异常预警响应可以认为是在客户端在进行完整性检验发现异常，即校验失败时，向客户端发送KEY的信息后服务端所做响应，该响应包括指示接收到KEY的信息的响应。
4.KEY的服务端加密，加密后得到加密md5。
5.KEY的完整性生成：加密KEY的md5码，KEY的烧录部分md5码生成。
系统端主要实现如下功能：
1.远程烧录成功宏控制；
2.远程烧录成功显示(工厂菜单部分)以反馈用户；
3.信息同步。
图4中额外KEY可以认为待烧录密钥。业务端可以认为是客户端。图4中服务端可以认为是远程设备端，系统端可以认为是电子设备板卡端。
本申请实施例提供的密钥烧录方法可以减少售后损失费用；为后期远程修复和烧录提供可执行途径；可以在第一时间响应客户反馈，提高客户满意度；可云端部署烧录策略，做可 控远程烧录。其中，本申请可以通过映射策略响应客户反馈，在用户有KEY需求变更时，可以通过更改映射策略以响应客户反馈。
