Description

一种数字货币钱包管理方法及远程控制方法、装置和系统
本申请要求于2021年10月22日提交的题为“一种数字货币钱包管理方法、装置和系统”的中国专利申请No.202111234552.5、以及于2021年10月28日提交的题为“一种数字货币钱包的远程控制方法、装置和系统”的中国专利申请No.202111264208.0的优先权,在此全文引用上述中国专利申请公开的内容以作为本申请的一部分或全部。
技术领域
本公开涉及计算机技术领域,尤其涉及一种数字货币钱包管理方法、装置和系统。
背景技术
基于安全单元(SE,Secure Element)实现的数字货币钱包因具有高安全性和近距通信能力(如蓝牙/NFC(Near Field Communication,近距离无线通信技术)等),可支持离线交易,交易双方钱包客户端无需与平台通信便可近距交互完成交易。
一方面,如果数字货币钱包离线时间过长,可能导致数字货币钱包的时钟失准,进而导致交易信息失真,影响到业务安全。另一方面,相关技术难以实现对离线状态(特别是在紧急情况下,处于离线状态下的数字货币钱包终端如遭受网络攻击、无法及时更新黑名单等风险钱包编号信息时)下的数字货币钱包进行远程控制,导致数字货币钱包的安全系数较低,且在移动蜂窝通信信号较差的情况下,由于向数字货币钱包终端发送的远程控制信息容易被干扰,导致远程控制效果较差。

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管理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管理方法,应用于数字货币钱包终端,主要包括以下步骤:
步骤S101:检测与数字货币平台之间的连接状态。
在本公开实施例中,可以发送至少一次与数字货币平台的连接请求;检测连接请求的连接结果,并根据连接结果,确定与数字货币平台之间的连接状态。
具体地,可以由数字货币钱包定时向数字货币平台发送心跳信号,以检测与数字货币平台之间的连接状态是否为离线状态;也可以在数字货币钱包每接收到一个交易请求时,向数字货币平台发送至少一次连接请求,以检测与数字货币平台之间的连接状态是否为离线状态;还可以在数字货币钱包每处理完一个交易请求时,向数字货币平台发送至少一次连接请求,以检测与数字货币平台之间的连接状态是否为离线状态;还可以在数字货币钱包递增接收到的交易请求的数量,当该数量大于预设数量阈值时,由数字货币钱包发送至少一次与数字货币平台的连接请求,以检测与数字货币平台之间的连接状态是否为离线状态。
步骤S102:在与数字货币平台之间的连接状态指示为离线状态的情况下,通过通信卫星获取当前时刻。
在本公开实施例中,在与数字货币平台之间的连接状态指示为离线状态的情况下,可以通过卫星授时模块,从卫星获取当前时刻。
具体地,该卫星授时模块可以是仅支持与北斗卫星通信的单模模式,此时卫星授时模块直接向北斗卫星发送最新时刻获取请求,并将北斗卫星返回的第一最新时刻作为当前时刻。
该卫星授时模块也可以是支持与北斗卫星以及GPS卫星进行通信的北斗/GPS双模方式,此时卫星授时模块分别向北斗卫星以及GPS卫星发送最新时刻获取请求。卫星授时模块可以将最先返回的时间值直接作为当前时刻。卫星授时模块也可以在接收到北斗卫星返回的第一最新时刻、GPS卫星返回的第二最新时刻,并记录北斗卫星的第一返回时长以及GPS卫星的第二返回时长之后,进一步确定第一返回时长是否小于第二返回时长,如果是,将第一最新时刻作为当前时刻,如果否,将第二最新时刻作为当前时刻。卫星授时模块还可以将第一最新时刻和第二最新时刻都发送给数字货币钱包,由数字货币钱包根据预设的业务策略从中选择当前时刻。
步骤S103:根据当前时刻以及自身保存的上一次同步时刻,计算离线时长。
在本公开实施例中,数字货币钱包内保存有与数字货币平台上一次进行同步的同步时刻。因此,数字货币钱包可以根据当前时刻以及上一次同步时刻,计算出自身的离线时长。
在本公开实施例中,在计算出自身的离线时长之后,可以将数字货币钱包内保存的同步时刻更新为当前时刻。
步骤S104:确定离线时长是否大于预设离线时长。
在本公开实施例中,数字货币钱包对应有预设离线时长,该预设离线时长可以由开发人员根据业务需求进行调整。举例来说,对于交易时间敏感的业务中所使用的数字货币钱包,可以将该数字货币钱包的预设离线时长设置得短一些,以使该数字货币钱包与数字交易平台尽快同步交易数据;而对于交易时间不敏感的业务中所使用的数字货币钱包,则可以将该数字货币钱包的预设离线时长设置得长一些,以减轻该数字货币钱包与数字交易平台之间同步交易数据的网络压力。
步骤S105:在确定出离线时长大于预设离线时长的情况下,生成钱包关键信息集,并将钱包关键信息集发送至数字货币平台,以使数字货币平台同步并处理钱包关键信息集。
在本公开实施例中,在确定出数字货币钱包离线时长大于预设离线时长的情况下,进一步包括:锁定数字货币钱包,并根据数字货币钱包内保存的钱包关键信息,执行生成钱包关键信息集的步骤。其中,钱包关键信息包括但不限于以下任意一个或多个:时间信息、定位信息、离线时长、数字货币信息、交易信息。
在本公开实施例中,根据数字货币钱包内保存的钱包关键信息,生成钱包关键信息集的过程,包括:对钱包关键信息进行加密,得到加密后的钱包关键信息;对加密后的钱包关键信息进行签名,得到签名标识,并将加密后的钱包关键信息以及签名标识作为钱包关键信息集,从而保证传输过程中钱包关键信息不被泄露、并且也避免了传输过程中钱包关键信息被假冒。
在本公开实施例中,将钱包关键信息集发送至数字货币平台的过程,包括:将钱包关键信息集上传至北斗卫星和/或GPS卫星,以使北斗卫星和/或GPS卫星将钱包关键信息集发送至数字货币平台,以使数字货币平台同步并处理钱包关键信息集。
在本公开实施例中,将钱包关键信息集上传至北斗卫星和/或GPS卫星,包括:将钱包关键信息集写入待发送的报文中;确定报文的长度是否大于自身的报文通信能力;在确定出报文的长度大于自身的报文通信能力的情况下,根据报文通信能力,对报文进行拆分;将拆分后的报文发送至北斗卫星和/或GPS卫星。
在本公开一个优选的实施例中,由北斗模块将钱包关键信息集上传至北斗卫星。其中,钱包关键信息集还可以包含报文标识area,报文标识area指示了待发送的报文的种类,该种类包括全球短报文以及区域短报文两种。北斗模块可以根据报文标识area确定采用何种短报文通信能力,具体地,如果待发送的报文为全球短报文,则北斗模块采用560比特通信能力,如果待发送的报文是区域短报文,则北斗模块采用14000比特通信能力。
北斗模块将钱包关键信息集写入待发送的报文中之后,需要确定报文的长度是否大于自身的报文通信能力,即确定待发送的报文的长度是否超过单条报文的负荷:如果是全球短报文,单条报文的负荷为560比特;如果是区域短报文,单条报文的负荷为14000比特。如果待发送的报文的长度超过单条报文的负荷,则由北斗模块负责将待发送的报文拆分为多条短报文再进行发送。
在本公开实施例中,在确定出报文的长度不大于自身的报文通信能力的情况下,北斗模块直接将报文发送至北斗卫星。在本公开一个优选的实施例中,北斗模块采用RDSS协议对待发送的报文或拆分后的报文进行封装和发送。
在本公开实施例中,北斗模块将待发送的报文或拆分后的报文发送至北斗卫星,并由北斗卫星采用RDSS协议中转下发至接收方北斗模块,其中,接收方北斗模块可以是第三方北斗运营商服务模块,也 可以是自建北斗服务模块。
接收方北斗模块接收北斗卫星发来的RDSS信号,解码获得报文或拆分后的报文。如果是未被拆分的报文,则接收方北斗模块直接将其提交给北斗网关;如果是拆分后的报文,则接收方北斗模块负责组装,得到完整的报文,再将完整的报文提交给北斗网关。
北斗网关从报文中解析出钱包关键信息集,并将钱包关键信息集提交数字货币平台,由数字货币平台对钱包关键信息集进行验签、解密、同步以及处理等操作。
在本公开实施例中,在将钱包关键信息集发送至数字货币平台之后,还包括:监听是否接收到数字货币平台返回的同步成功信息;在预设时间内未接收到同步成功信息的情况下,向数字货币平台重新发送钱包关键信息集,并返回执行监听是否接收到数字货币平台返回的同步成功信息的步骤,从而确保数字货币平台接收到钱包关键信息集,提高数字货币平台同步的准确率。
根据本公开实施例的一种数字货币钱包管理方法可以看出,该方法能够在与数字货币平台之间的连接状态指示为离线状态的情况下,通过通信卫星获取当前时刻并计算离线时长,在确定出离线时长大于预设离线时长的情况下,生成钱包关键信息集,并将钱包关键信息集发送至数字货币平台,以使数字货币平台同步并处理钱包关键信息集,从而保证了数字货币钱包在离线期间的时钟准确度,进而保证了交易信息的准确性。

通过上述设置,使得在满足远程控制触发条件下,生成远程控制指令,通过后续经由北斗卫星系统将远程控制指令以报文的形式发送至相应的数字货币钱包终端(即目标数字货币钱包终端),使得,即使数字货币钱包终端处于离线状态下,或者当前移动蜂窝通信的通信信号较差的情况下(此时信号容易被干扰),实现对数字货币钱包终端的远程控制,且能够保障远程控制效果。
可选地,根据本公开实施例,在生成远程控制指令的步骤之后,上述方法还包括:
对远程控制指令进行加密处理;
对加密处理后的远程控制指令进行签名处理。
根据本公开实施例的一具体实施方式,对远程控制指令S(其中包括但不限于指令编码code、指令序列号seqID、指令下发时间time、指 令发送的报文区域area(区域短报文/全球短报文,可据此确定需要进行远程控制,即接收远程控制指令的目标数字货币钱包终端的钱包编号,以及北斗通信模块编号)采取约定密钥进行加密得到S’;进一步地,还可根据实际需要,对加密后的远程控制指令S’的哈希值hash进行签名得到sign值。
根据本公开实施例,可根据预设的密钥(仅为示例,也可采取任何现有的其他加密方式)对生成的远程控制指令进行加密处理,以避免远程控制指令被篡改等;同时,对远程控制指令进行签名处理可根据实际情况决定是否执行,容易理解的是,对远程控制指令进行签名,有助于后续接收到该远程控制指令的数字货币钱包终端通过验证签名确保远程控制指令合法可信,进一步保障远程控制效果。
步骤S502,将远程控制指令发送至北斗卫星系统,以使得:北斗卫星系统根据钱包编号,以报文形式将远程控制指令转发至处于离线状态的目标数字货币钱包终端,以实现目标数字货币钱包终端在离线状态下的远程控制。
可选地,根据本公开实施例,上述远程控制指令包括限制交易指令,以使接收到限制交易指令的目标数字货币钱包终端停止离线交易。
可选地,当所满足的远程控制触发条件包括“数字货币平台和/或任一数字货币钱包终端对应的风险等级超过风险等级阈值”时,通过向相应的数字货币钱包终端(即目标数字货币钱包终端)发送限制交易指令,有助于目标数字货币钱包终端在接收到该限制交易指令后,对钱包终端进行锁定,暂时停止交易。
可选地,根据本公开实施例,远程控制指令还可以包括更新的风险钱包编号列表。当所满足的远程控制触发条件包括“任一数字货币钱包终端内存储的风险钱包编号列表与数字货币平台内存储的风险钱 包编号列表不一致”时,目标数字货币钱包终端接收到远程数字指令后,判断交易对方的钱包编号是否属于更新后的风险钱包编号列表,若属于,即交易方的数字货币钱包属于存在风险的数字货币钱包,则暂停交易;若不属于,即交易方的数字货币钱包并不属于存在风险的数字货币钱包,可继续进行交易。通过上述设置,可根据实际情况、所满足的远程控制触发条件来生成不同的远程控制指令,使得在移动蜂窝通信信号较差的情况下,尤其是离线情况下,对用户的数字货币钱包终端进行远程控制,保障了用户的数字货币钱包的资产安全。
可选地,根据本公开实施例,上述方法还包括:

通过上述设置,可以根据所传输的远程控制指令对应的目标数字货币钱包终端的数量、所属区域,以及所传输的远程控制指令的类型,灵活选择不同的发送方式,进而提升远程控制指令的发送效率。
根据本公开实施例的技术方案,因为采用根据业务安全需求设置远程控制触发条件,在满足远程控制触发条件下,生成远程控制指令;其中,远程控制指令指示了目标数字货币钱包终端对应的钱包编号以及操作方式;将远程控制指令发送至北斗卫星系统,以使得:北斗卫星系统根据钱包编号,以报文形式将远程控制指令转发至处于离线状态的目标数字货币钱包终端,以实现目标数字货币钱包终端在离线状态下的远程控制的技术手段,所以克服了现有方法中对离线状态下的数字货币钱包难以进行有效的远程控制,导致数字货币钱包的安全系数较低、远程控制效果较差的技术问题,进而在离线模式下,通过北斗卫星系统将数字货币平台生成的远程控制指令发送至数字货币钱包终端,以实现对处于离线状态的数字货币钱包的远程控制,达到了显著提高数字货币钱包终端的安全系数,提升远程控制效果,提升所转发的信息的抗干扰能力的技术效果。
图6是根据本公开实施例提供的另一种数字货币钱包的远程控制方法的主要流程的示意图;如图6所示,本公开实施例提供的数字货币钱包的远程控制方法,应用于北斗卫星系统,主要包括:
步骤S601,接收数字货币平台发送的远程控制指令,其中,远程控制指令指示了目标数字货币钱包终端对应的钱包编号和操作方式。
具体地,根据本公开实施例,北斗卫星系统接收数字货币平台通过北斗网关发送的远程控制指令,根据本公开实施例的一具体实施方式,数字货币平台以透传方式(即透明传送,是指只负责将需要传送的业务传送到目的节点,同时保证传输的质量即可,而不对传输的业务进行处理,仅为示例,也可采用现有的能够保障传输质量的传输方式)将远程控制指令发送至北斗卫星系统;北斗卫星系统利用与数字货币平台对应的北斗模块,接收数字货币平台经由北斗网关发送的远程控制指令。其中,北斗网关主要作为连接数字货币平台与北斗卫星系统(主要连接北斗卫星系统下的北斗通信模块,简称北斗模块)的媒介。
根据本公开实施例,由于数字货币平台常常需要大批量发送远程控制指令(如针对更新的风险钱包编号列表的情形,常常需要向区域内的多个数字货币钱包终端发送远程控制指令(主要针对区域内处于信号较差、或者离线状态下的数字货币钱包终端),此时,利用北斗网关可以将远程控制指令发送至合适的北斗模块,进而经由北斗卫星系统分别转发至多个数字货币钱包终端。
步骤S602,根据北斗报文协议对远程控制指令进行编码,得到目标报文。
通过上述设置,根据北斗报文协议将远程控制指令编码为报文,使得远程控制指令能够利用北斗卫星系统特有的短报文通信能力进行 离线转发。此外,由于现有移动蜂窝通信如2G/3G/4G/5G、NB-IOT、WIFI通信等存在覆盖范围有限、紧急情况容易被干扰等问题,因此,在移动蜂窝通信的通信信号较为薄弱时,也可利用北斗卫星系统的通信能力进行远程控制指令的转发。
具体地,根据本公开实施例,上述根据北斗报文协议对远程控制指令进行编码,得到目标报文的步骤之后,包括:
根据北斗报文协议对远程控制指令进行编码,得到报文;
根据北斗卫星系统对应的报文传输能力对报文进行拆分,得到目标报文。
根据本公开实施例的一具体实施方式,北斗通信模块根据发送信号范围area确定所采用的短报文通信能力,如全球短报文采用560比特传输能力,区域短报文采用14000比特能力;如果待发送的远程控制指令编码后的报文长度(S’+sign)超过单条报文的负荷,则由北斗模块负责将长报文拆分为多条短报文进行发送。
根据本公开实施例,根据所传输/发送的信息辐射范围的不同,北斗卫星系统的单次通信能力(即单次传输报文的负荷、以及对应的时间间隔)存在一定的差异。若针对远程控制指令编码后确定的报文的长度超过北斗卫星系统的单词报文传输能力,可以对报文进行拆分,得到多个短报文(即目标报文)。
步骤S603,根据钱包编号将目标报文转发至目标数字货币钱包终端,以使得:目标数字货币钱包终端对目标报文进行解码得到远程控制指令,根据远程控制指令中指示的操作方式实现离线状态下的远程控制。
根据本公开实施例的一具体实施方式,目标报文通过北斗短报文天线发出,由北斗卫星接收到信号并将其中转下发,如果多条短报文, 则分别发送。
可选地,根据本公开实施例,远程控制指令还指示了目标数字货币钱包终端对应的北斗通信模块编号;根据钱包编号将目标报文转发至目标数字货币钱包终端,包括:
根据北斗通信模块编号和钱包编号,将目标报文转发至目标数字货币钱包终端;其中,目标数字货币钱包终端对应的数量为一个或多个。
可选地,根据本公开实施例,根据北斗通信模块编号、钱包编号,将报文形式的远程控制指令发送至目标数字货币钱包的北斗通信模块,以使得该北斗通信模块对该报文形式的远程控制指令进行解码,进而使得目标数字货币钱包能够对解码后的对应的远程控制指令进行解密、验证签名等操作后,根据远程控制指令中的操作方式实现离线状态、或信号薄弱情况下的远程控制。
通过上述设置,使得即使数字货币钱包终端处于离线状态下,或者当前移动蜂窝通信的通信信号较差的情况下(此时信号容易被干扰),实现对数字货币钱包终端的远程控制,且能够保障远程控制效果。

步骤S702,对目标报文进行解码,得到远程控制指令;其中,远程控制指令指示了目标数字货币钱包终端对应的操作方式。

步骤S703,根据操作方式进行相应操作,以实现离线状态下的远程控制。
具体地,根据本公开实施例,上述远程控制指令包括限制交易指令,以使接收到限制交易指令的目标数字货币钱包终端停止离线交易。即,当所满足的远程控制触发条件包括“数字货币平台和/或任一数字货币钱包终端对应的风险等级超过风险等级阈值”时,目标数字货币钱包终端在接收到该限制交易指令后,对钱包终端进行锁定,可暂时停止交易。
可选地,根据本公开实施例,远程控制指令还可以包括更新的风险钱包编号列表。当所满足的远程控制触发条件包括“任一数字货币钱包终端内存储的风险钱包编号列表与数字货币平台内存储的风险钱包编号列表不一致”时,目标数字货币钱包终端接收到远程数字指令后,判断交易对方的钱包编号是否属于更新后的风险钱包编号列表,若属于,即交易方的数字货币钱包属于存在风险的数字货币钱包,则暂停交易;若不属于,即交易方的数字货币钱包并不属于存在风险的数字货币钱包,可继续进行交易。通过上述设置,使得在移动蜂窝通信信号较差的情况下,尤其是离线情况下,对用户的数字货币钱包终端进行远程控制,保障了用户的数字货币钱包的资产安全。
