具体实施方式
以下结合附图对本公开的示范性实施例做出说明，其中包括本公开实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本公开的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
需要指出的是，在不冲突的情况下，本公开的实施例以及实施例中的技术特征可以相互结合。
图1是根据本公开实施例的一种数字货币钱包的更新方法的主要步骤的示意图。
如图1所示，本公开实施例的一种数字货币钱包的更新方法应用于设置有数字货币钱包的终端时主要包括以下步骤：
步骤S101：根据用户触发，向可信平台发送关于数字货币钱包是否需要更新的查询请求。
在本公开实施例中，为了保证数字货币交易的安全性，数字货币钱包为一般安装在安全芯片中的硬件钱包，例如安装于手机SE(Secure Element，安全元件)、SIM卡(Subscriber Identity Module，用户身份识别模块)或IC卡(Integrated Circuit Chip，微型电子器件)等不同安全芯片上的硬件钱包。可以理解的是，本公开实施例所描述的数字货币钱包或硬件钱包是安全芯片上的一个应用，也即，数字货币钱包实际为数字货币钱包应用，硬件钱包为硬件钱包应用。
可以理解的是，在执行本公开实施例提供的数字货币钱包的更新方法之前，安全芯片已通过写卡设备成功进行了硬件钱包的申请、下载、安装、个人化及开立操作，处于正常可交易状态。并且可信平台上已上传有硬件钱包不同版本的安装包，在有新版本的硬件钱包时，可信平台也可获取新版本的硬件钱包。另外，可信平台作为硬件钱包生命周期的管理系统，其具有根据渠道、厂商和版本号等多维度进行应用管理的能力。其中，渠道指对应于不同支付应用来源的支付渠道。
在终端用户通过终端上的钱包app进入硬件钱包操作页面时，即发起了对硬件钱包的触发，此时终端通过钱包app向可信平台发送关于该 终端的安全芯片上的硬件钱包是否需要更新的查询请求。值得注意的是，钱包app是运行在终端上的应用程序，与其不同的是，硬件钱包(数字货币钱包)是运行在安全芯片上的程序。
步骤S102：接收所述可信平台根据所述查询请求返回的查询结果。
可信平台在接收到终端发送的关于数字货币钱包是否需要更新的查询请求之后，根据数字货币钱包对应的配置信息确定数字货币钱包是否需要更新。例如，可信平台根据数字货币钱包的版本号、渠道和厂商等信息综合判断后，确定数字货币钱包是否需要更新。进一步地，在确定出数字货币钱包有所修改时，可信平台还可根据数字货币钱包的修改内容确定数字货币钱包是否需要强制更新，例如，数字货币钱包升级了较严重的安全漏洞时，确定数字货币钱包需要强制更新；若数字货币钱包仅升级了不影响功能使用、但可能对用户体验有微弱影响的内容(如仅更新了界面的显示色彩布局)，则可确定数字货币钱包为非强制更新。
可信平台在确定出数字货币是否需要更新以及是否需要强制更新之后，将查询请求对应的查询结果返回给终端，使得终端可根据查询请求确定是否发起更新请求。步骤S103：在所述查询结果指示了所述数字货币钱包需要更新的情况下，针对所述数字货币钱包中的数字货币进行提现，以及同步所述数字货币钱包的离线交易数据，并向所述可信平台发送更新请求。
在本公开一个实施例中，终端在接收到可信平台返回的查询结果之后，终端上的钱包app可根据查询结果判断是否向可信平台发送更新请求。若钱包app确定出查询结果指示数字货币钱包需要更新且需要强制更新，终端上的钱包app向可信平台发送更新请求。或者，在查询结果指示需要更新但非强制更新的情况下，终端上的钱包app可根据业务需求或者用户判断确定发起更新请求，例如，钱包app通过终端触摸屏 向用户展示关于数字货币钱包的更新提示，如用户拒绝更新，则终端不向可信平台发起更新请求，数字货币钱包的更新流程即可终止。再比如，在查询结果指示数字货币无需更新的情况下，钱包app也不向可信平台发起更新请求，数字货币钱包的更新流程也终止。
在钱包app确定出需要向可信平台发起更新请求之后，在钱包app将更新请求发送给可信平台之前，由于在数字货币钱包的更新过程中，需要删除终端上原有的数字货币钱包，为避免数字货币的损失，终端先针对数字货币钱包中的数字货币进行提现，并同步数字货币钱包的离线交易数据。具体地，终端可通过展示提现引导信息，引导用户进行提现操作，并且将数字货币钱包中的离线交易数据同步至数字货币钱包对应的管理平台，使得管理平台对应记录数字货币钱包的账号(如钱包ID)、关联码和账户数据(交易数据和证书等)。
其中，关联码主要用于数字货币钱包的管理平台与可信平台之间的秘密通信，关联码与账号一一对应，在管理平台和可信平台通信时，将关联码作为数字货币钱包的标识，而避免直接发送数字货币钱包的账号，从而避免数字货币钱包的账号被窃取而造成的交易风险。另外，在终端向其对应的管理平台同步离线交易数据之后，管理平台记录的账户数据即是包括在线交易数据和离线交易数据的完整交易数据，后期在根据该账户数据更新数字货币钱包时，依据的也是完整交易数据，从而提高账户安全性和可用性，有利于提高用户体验。
步骤S104：接收所述可信平台根据所述更新请求发送的目标更新指令，所述目标更新指令指示了与所述数字货币钱包对应的账户数据。
终端在完成提现、离线数据同步操作后，即向可信平台发送更新请求。可信平台在接收到更新请求之后记录数字货币钱包对应的更新申请信息，并设置该数字货币钱包在可信平台中的状态为“更新中”，然后组织下发更新初始化指令。
终端在接收可信平台发送的更新初始化指令之后，相应设置数字货币钱包的当前状态。具体地，在本公开一个实施方式中，终端接收可信平台发送的更新初始化指令，所述更新初始化指令指示了所述数字货币钱包的状态；根据所述更新初始化指令，确定所述数字货币钱包中是否存在数字货币余额；如果否，根据所述更新初始化指令所指示的状态，设置所述数字货币钱包的当前状态，并向所述可信平台返回第一状态码，以使所述可信平台根据所述第一状态码发送所述目标更新指令。
在此实施方式中，终端上的钱包app接收可信平台下发的更新初始化指令，该更新初始化指令指示了数字货币钱包的状态为“更新中”。钱包app将该更新初始化指令发送给安全芯片上的数字货币钱包，由数字货币钱包判断是否还存在数字货币余额等其他未同步的信息，如存在数字货币余额等信息，则向钱包app返回表征错误的第二状态码，由钱包app将该第二状态码发送给可信平台。若不存在数字货币余额等信息，则向钱包app返回表征正常的第一状态码，由钱包app将该第一状态码发送给可信平台，以使可信平台根据该表征正常的第一状态码组织目标更新指令。并且，在不存在数字货币余额等信息的情况下，数字货币钱包还根据更新初始化指令中的状态(更新中)，将自身的当前状态设置为待更新状态，并限制离线交易操作，以避免在更新过程中因其他操作(如交易操作)造成数据丢失，提高更新过程的安全性。
终端在向可信平台发送表征正常的第一状态码之后，可信平台可根据个人化数据请求报文，通知该管理平台相应的数字货币钱包需要进行更新操作，并从数字货币钱包对应的管理平台获取更新所需的个人化数据，也即账户数据，例如钱包ID、用于报文加密的密钥、计算MAC的密钥和用于交易认证的密钥以及关联码等信息。获取到更新所需的管理平台侧的个人化数据之后，可信平台根据数字货币钱包类型(安装于手机SE、SIM卡、IC卡等不同安全芯片上的硬件钱包应用) 组织目标更新指令(包括删除指令、下载指令、安装指令、个人化指令等)，并将目标更新指令下发给终端。
当然，若钱包app向可信平台发送了第二状态码，可信平台即可根据该表征错误的第二状态码终止响应终端所发送的更新请求，并且删除该终端的数字货币钱包对应的更新申请信息及状态值，并进一步向终端返回错误码，由终端上的钱包app提示用户无法进行更新。
步骤S105：根据所述目标更新指令所指示的所述账户数据，对所述数字货币钱包进行更新。
在本公开一个实施例中，目标更新指令包括删除指令和安装指令，终端则可根据所述删除指令，对所述数字货币钱包进行删除，并根据所述安装指令所指示的安装包，下载并安装与所述安装包对应的新的数字货币钱包；然后根据所述账户数据开设所述新的数字货币钱包。
如上所述，目标更新指令可以包括删除指令、下载指令、安装指令和个人化指令流，可信平台可以分批次下发这些指令，由终端上的钱包app转发给安全芯片上的数字货币钱包，数字货币钱包根据删除指令删除原有的数字货币钱包，并根据下载指令下载新版本的数字货币钱包的安装包，然后根据安装指令安装新版本的数字货币钱包，然后进一步根据个人化指令包括的该数字货币钱包对应的个人化数据(账户数据)开设新的数字货币钱包。
在安全芯片将删除指令、下载指令、安装指令和个人化指令流全部执行成功之后，可以通过钱包app向可信平台发送钱包证书申请数据，用以申请新的数字货币钱包对应的证书以及其他账户数据，如昵称和历史交易记录等。可信平台依据执行成功的反馈，并从终端获取钱包证书申请数据之后，通知该数字货币钱包对应的管理平台进行更新开立操作，获取更新的开立应答数据(包括硬件钱包开立指令、证书、 昵称和历史交易记录等)，并将开立应答数据发送给终端中安全芯片上的数字货币钱包，数字货币钱包根据开立应答数据成功执行开立操作之后，向可信平台返回开立执行结果，可信平台将开立执行结果作为开立完成通知转发给管理平台，管理平台根据该开立完成通知将更新后的数字货币钱包的当前状态设置为可用状态，并向可信平台返回开立完成响应。此后，更新后的数字货币钱包即处于正常可交易状态。
值得注意的是，在更新过程中，若出现更新失败的情况，终端可提示用户再次发起更新请求，可信平台在接收到该更新请求之后，可根据该终端首次发起更新请求时记录的更新申请信息继续完成更新操作。
根据本公开实施例的一种数字货币钱包的更新方法可以看出，设置有数字货币钱包的终端可以向可信平台查询数字货币钱包是否需要更新，在需要更新的情况下，根据可信平台发送的目标更新指令中的账户数据，对数字货币钱包进行更新，从而使得更新后的数字货币钱包对应的账户数据不变，仍可实现历史交易记录等数据的查询，从而提高用户体验。进一步地，在需要更新的情况下，设置有数字货币钱包的终端先对数字货币钱包中的数字货币进行提现，并同步数字货币钱包的离线交易数据，一方面避免在更新过程中造成数字货币的损失，另一方面也可以保证目标更新指令中的账户数据是包含离线交易数据的完整数据，从而提高账户安全性和可用性。
图2是根据本公开实施例的一种用于更新数字货币钱包的终端的主要模块的示意图。如图2所示，本公开实施例的一种用于更新数字货币钱包的终端200包括：查询交互模块201、处理模块202和更新模块203；其中，

在本公开一个实施例中，所述更新模块203，还用于接收所述可信平台发送的更新初始化指令，所述更新初始化指令指示了所述数字货币钱包的状态；根据所述更新初始化指令，确定所述数字货币钱包中是否存在数字货币余额；如果否，根据所述更新初始化指令所指示的状态，设置所述数字货币钱包的当前状态，并向所述可信平台返回第一状态码，以使所述可信平台根据所述第一状态码发送所述目标更新指令。
在本公开一个实施例中，所述更新初始化指令所指示的状态为更新中状态；所述更新模块203，还用于限制所述数字货币钱包的离线交易操作。
在本公开一个实施例中，所述更新模块203，还用于在所述数字货币钱包中存在数字货币余额的情况下，向所述可信平台返回第二状态码，以使所述可信平台根据所述第二状态码终止响应所述更新请求。
在本公开一个实施例中，所述更新模块203，还用于在所述根据所述目标更新指令所指示的所述账户数据，对所述数字货币钱包进行更新之后，将所述数字货币钱包的当前状态设置为可用状态。
在本公开一个实施例中，所述目标更新指令包括删除指令和安装 指令；所述更新模块203，用于根据所述删除指令，对所述数字货币钱包进行删除，并根据所述安装指令所指示的安装包，下载并安装与所述安装包对应的新的数字货币钱包；根据所述账户数据开设所述新的数字货币钱包。

根据本公开实施例的一种用于更新数字货币钱包的终端可以看出，设置有数字货币钱包的终端可以向可信平台查询数字货币钱包是否需要更新，在需要更新的情况下，根据可信平台发送的目标更新指令中的账户数据，对数字货币钱包进行更新，从而使得更新后的数字货币钱包对应的账户数据不变，仍可实现历史交易记录等数据的查询，从而提高用户体验。进一步地，在需要更新的情况下，设置有数字货币钱包的终端先对数字货币钱包中的数字货币进行提现，并同步数字货币钱包的离线交易数据，一方面避免在更新过程中造成数字货币的损失，另一方面也可以保证目标更新指令中的账户数据是包含离线交易数据的完整数据，从而提高账户安全性和可用性。
图3是根据本公开实施例的一种数字货币钱包的更新系统的主要模块的示意图。如图3所示，本公开实施例的一种数字货币钱包的更新系统300包括：可信平台301、数字货币钱包对应的管理平台302、以及上述任一实施例提供的用于更新数字货币钱包的终端200；其中，
所述可信平台301，用于根据所述终端200发送的关于数字货币钱包是否需要更新的查询请求、以及所述数字货币钱包对应的配置信息，确定所述数字货币钱包是否需要更新，并向所述终端200返回查询结果；在接收到所述终端发送的更新请求后，从所述数字货币钱包对应的管理平台302获取与所述数字货币钱包对应的账户数据，并根据所 述账户数据向所述终端200发送目标更新指令。
下面结合数字货币钱包的更新系统的架构，对本公开实施例提供的数字货币钱包的更新方法进行进一步说明。其中，终端中包括钱包app和数字货币钱包应用，钱包app是运行在终端上的应用程序，数字货币钱包是运行在安全芯片上的程序，终端上的钱包app用于与可信平台通信，而运行于安全芯片上的数字货币钱包不与可信平台直接通信，以保证安全性。如图4所示，该方法可以包括以下步骤：
步骤S401：终端根据用户触发，向可信平台发送关于数字货币钱包是否需要更新的查询请求。
在终端用户通过终端上的钱包app进入硬件钱包操作页面时，即发起了对硬件钱包的触发，此时终端通过钱包app向可信平台发送关于该终端的安全芯片上的硬件钱包是否需要更新的查询请求。
步骤S402：可信平台根据数字货币钱包对应的配置信息，确定数字货币钱包是否需要更新，并向终端返回相应的查询结果。
步骤S403：钱包app在确定出查询结果指示了数字货币钱包需要更新的情况下，引导用户针对数字货币钱包中的数字货币进行提现，以及同步数字货币钱包的离线交易数据。
在此步骤中，若查询结果指示数字货币钱包无需更新，则数字货币钱包的更新流程即可结束，在此情况下，可以引导用户进行数字货币提现以及离线交易数据的同步，也可以维持数字货币钱包现有的工作状态，即不引导用户进行数字货币提现以及离线交易数据的同步。
步骤404：完成钱包app向可信平台发送更新请求。
步骤S405：可信平台设置数字货币钱包的状态，并根据数字货币钱包的状态，向钱包app下发更新初始化指令，由钱包app将更新初始 化指令发送给数字货币钱包。
步骤S406：数字货币钱包根据更新初始化指令，确定数字货币钱包中是否存在数字货币余额，如果是，执行步骤S407，否则执行步骤S408。
步骤S407：通过钱包app向可信平台发送第二状态码，以使所述可信平台根据所述第二状态码终止响应所述更新请求。
第二状态码表征数字货币钱包处于错误状态，无法进行更新。可信平台可以根据该第二状态码终止响应更新请求，则数字货币钱包的更新流程即可结束。在此情况下，可信平台可向钱包app返回错误码，由钱包app提示用户不能进行更新。用户也可根据提示再次发起更新请求，可信平台可以根据首次发起更新请求时的更新申请信息继续完成更新操作。
步骤S408：限制数字货币的离线交易操作，通过钱包app向可信平台发送第一状态码；并执行步骤S409。
该第一状态码表征数字货币钱包处于正常状态，可以更新。数字货币钱包在确定不存在数字货币余额等未同步的数据之后，可以根据更新初始化指令中的状态(更新中)，设置数字货币钱包的当前状态(待更新)，以限制数字货币钱包的离线交易操作。
步骤S409：可信平台向数字货币钱包对应的管理平台发送个人化数据请求报文，以通知管理平台数字货币钱包需要进行更新操作，并从管理平台获取与数字货币钱包对应的个人化数据。
可以理解的是，个人化数据即为数字货币钱包对应的一部分账户数据，其可包括账户ID、密钥和关联码等。
步骤S410：可信平台向钱包app下发目标更新指令，由钱包app将目标更新指令转发给数字货币钱包所在的安全芯片，使得安全芯片 执行目标更新指令。
该目标更新指令包括删除指令、下载指令、安装指令和个人化指令流，可信平台可分批次下发这些指令，使得安全芯片执行这些指令，以删除原有的数字货币钱包应用，以及下载安装新的数字货币钱包应用。
步骤S411：数字货币钱包通过钱包app向可信平台发送证书申请数据。
步骤S412：可信平台根据证书申请数据，通知管理平台进行更新开立操作，并获取更新开立应答数据。
其中，更新开立应答数据中包括钱包开立指令。该更新开立应答数据也为数字货币钱包对应的部分账户数据，其可以包括数字货币钱包对应的证书、昵称和历史交易记录等。可以理解的是，钱包开立指令也属于目标更新指令，通过钱包开立指令以及证书、昵称和历史交易记录等账户数据，实现了新版本的数字货币钱包的开立，开立后的新版数字货币钱包处于可用状态。
步骤S413：可信平台将更新开立应答数据发送给钱包app，由钱包app将开立应答数据转发给数字货币钱包，使得数字货币钱包根据开立应答数据完成开立过程。
步骤S414：数字货币钱包通过钱包app向可信平台返回开立结果，并由可信平台将开立结果转发给管理平台。
完成开立后，新版本的数字货币钱包即处于可用状态，由于其是根据旧版本的账户数据进行更新的，因此更新后的数字货币钱包的钱包ID、昵称和历史交易记录等均不变，使得历史交易记录可查询。
根据本公开实施例提供的数字货币钱包的更新系统可以看出，设 置有数字货币钱包的终端可以向可信平台查询数字货币钱包是否需要更新，在需要更新的情况下，根据可信平台发送的目标更新指令中的账户数据，对数字货币钱包进行更新，从而使得更新后的数字货币钱包对应的账户数据不变，仍可实现历史交易记录等数据的查询，从而提高用户体验。进一步地，在需要更新的情况下，设置有数字货币钱包的终端先对数字货币钱包中的数字货币进行提现，并同步数字货币钱包的离线交易数据，一方面避免在更新过程中造成数字货币的损失，另一方面也可以保证目标更新指令中的账户数据是包含离线交易数据的完整数据，从而提高账户安全性和可用性。
