为了更清楚地说明本发明实施例的技术方案, 下面将对实施例描述中所需要使用的附 图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一些实施例, 对于本领 域的普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他附 图。
图 1为本发明提供的动态口令的输出方法的流程示意图;
图 2为本发明提供的移动终端实施例的结构示意图;
图 3为本发明提供的智能密钥设备实施例的结构示意图。 具体实施方式 下面结合本发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描 述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发 明的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例, 都属于本发明的保护范围。
下面将结合附图对本发明实施例作进一步地详细描述。
图 1为本发明提供的动态口令的输出方法的流程示意图。 图 1所示方法实施例, 包括: 步骤 101、 移动终端通过第一接口与智能密钥设备相连;
其中, 移动终端可以为手机、 平板电脑等便携式终端;
所述第一接口可以短距离通信接口, 也可以是以耦合方式相连的硬件接口, 如音频接 口或 OTG (On-The-Go) 接口。
优选的, 采用硬件接口方式相连, 能够防止黑客的监听, 从而保证信息传输的安全性。 步骤 102、 所述移动终端输出提示用户输入挑战码的信息;
具体的, 移动终端可以通过一个交互界面请求用户输入信息, 该交互界面的内容, 可 以根据实际需要进行自定义。
步骤 103、 所述移动终端对所述移动终端接收的按键信息进行检测, 得到检测结果; 具体的, 所述移动终端通过在交互页面上用户针对该提示信息输入内容进行检测; 其 中用户可以通过手机的硬件键盘或触摸屏上的键盘等实现对上述提示信息的反馈。
步骤 104、 所述移动终端对所述检测结果进行解析, 得到挑战码;
由步骤 102至 104可以看出, 挑战码的输入由原来在动态口令牌上操作, 转移到移动 终端上, 满足了用户手动输入挑战码的基本要求, 且由于借用了移动终端上的按键功能, 无需在动态口令牌上部署按键信息, 达到了缩小动态口令牌体积的目的。
步骤 105、 所述移动终端对所述挑战码进行编码得到编码数据;
具体的, 在实际应用中, 移动终端与智能密钥设备相连时使用的接口不同, 对应的编 码方式也存在不同, 例如, 如果使用音频接口传输挑战码, 则将挑战码编码成音频接口能 够支持的编码码字。
步骤 106、 所述移动终端将所述编码数据通过所述第一接口发送至所述智能密钥设备; 具体的, 发送方式可以按照该接口对应的传输协议或传输标准进行, 此处不再赘述。 步骤 107、 所述智能密钥设备在通过所述第一接口接收到所述编码数据后, 对所述编 码数据进行解码, 以得到所述挑战码;
具体的, 智能密钥设备获取该编码方式对应的解码方式, 利用该解密方式对该编码数 据进行解码, 得到挑战码。 步骤 108、 所述智能密钥设备在得到所述挑战码后, 输出所述挑战码;
其中, 输出方式包括智能密钥设备通过音频播输出接口播放该挑战码, 通过显示屏显 示该挑战码, 当然, 还可以是方便用户获知智能密钥设备接收到的挑战码的其他方式。
步骤 109、 所述智能密钥设备接收对所述挑战码的确认信息;
其中, 所述智能密钥设备通过检测用户是否按下确认键等方式来获取确认信息。
需要说明的是, 步骤 108和步骤 109通过输出挑战码, 并接收用户对挑战码的确认信 息, 方便用户确认挑战码在传输过程中是否被修改, 从而保证数据的安全性, 以保证信息 的安全。
步骤 110、 所述智能密钥设备接收到所述挑战码的确认信息后, 发起根据所述挑战码 生成动态口令的流程;
具体的, 在接收到挑战码的确认信息后, 可以直接进行动态口令的生成操作, 也可以 在生成动态口令前执行如下操作:
所述智能密钥设备对所述挑战码进行解析, 得到所述挑战码对应的交易信息, 输出所 述交易信息; 在接收到对所述交易信息确认的指令后, 再根据所述挑战码生成动态口令; 在接收到对所述交易信息取消的指令后, 则结束生成动态口令的流程。
由于将挑战码区分为若干部分,可以提示用户知晓待输入挑战码实际含义的提示信息, 用户根据提示信息依次输入挑战码的每个部分, 从而可以根据提示用户知晓待输入挑战码 实际含义的提示信息以及待输入的挑战码来确认此次交易是否是用户需要的真正交易, 从 一定程度上防止了黑客进行钓鱼的行为, 保证了用户财产的安全。
举例来说, 输入挑战码的规则为目标帐号后 6位和交易金额, 利用挑战码业务规则解 析用户输入挑战码意义, 并进行提示。 如挑战码为 1234569999, 业务规则为目标帐号后 6 为和交易金额, 那么令牌在解析后将对用户提示: "转账交易, 目标帐号为 123456, 转账金 额为 9999, 您确认进行转账吗? 如果确认请按确认键, 否则按取消键取消交易"; 用户进行 确认或取消。 根据用户选择进行: 如果用户确认交易, 就计算并显示动态密码, 然后退出; 如果用户取消交易, 那么不计算动态密码, 直接退出。
其防止欺诈交易的过程如下: 用户受到诱骗, 访问黑客开设的钓鱼网站。 钓鱼网站将 要求用户输入伪造的挑战码到令牌, 如输入信息" 3749599999"。 按照业务规则对该挑战码 解析后, 令牌对用户提示: "转账交易, 目标帐号为 37495, 转账金额为 99999, 您确认进 行转账吗? 如果确认请按确认键, 否则按取消键取消交易"; 用户通过阅读, 可以看出这 个挑战码对应的交易并非自身发起的交易, 因此按取消键取消本次动态口令的生成操作, 从而保证了自身账号安全。 步骤 111、 输出所述动态口令。
其中, 输出方式包括智能密钥设备通过音频播输出接口播放该挑战码, 通过显示屏显 示该挑战码等。
本发明提供的方法实施例, 通过将挑战码的输入由原来在动态口令牌上操作, 转移到 移动终端上, 满足了用户手动输入挑战码的基本要求; 借用了移动终端上的按键功能, 无 需在动态口令牌上部署按键, 大幅减少了按键个数, 降低了成本, 达到了缩小动态口令牌 体积的目的; 移动终端在对按键信息进行检测后, 通过解析操作, 获取到挑战码, 再对挑 战码进行编码, 通过移动终端和动态口令牌之间的传输接口完成挑战码的传输, 再由动态 口令牌对编码数据进行解码, 实现动态口令牌获取挑战码的操作, 无需增加硬件成本的情 况下, 实现了挑战码从移动终端到动态口令牌的传输, 实现简单; 另外, 在执行动态口令 生成之前, 动态口令牌会输出该挑战码, 以方便用户确认动态口令牌接收到的挑战码是否 为用户实际输入的账号, 以防止移动终端上存在非法软件, 对移动终端解析后的挑战码进 行修改等问题的出现, 防止钓鱼网站的攻击, 保证账号安全。
需要说明的是, 所述智能密钥设备在接收到交易信息后, 对交易信息进行签名, 得到 签名数据。 因此, 上述智能密钥设备不但能够进行口令生成, 也可以在接收到交易信息生 成签名数据, 从而集成于动态口令和数字签名两个功能的设备, 降低了生产成本。
其中, 所述智能密钥设备还可以获取所述交易信息中的关键信息, 并输出所述关键信 息, 接收对所述关键信息的确认信息, 并触发签名模块执行签名操作。
需要说明的是, 所述交易信息中的关键信息可以为账号信息、 金额信息等, 通过将关 键信息显示给用户, 防止黑客对交易信息的修改, 降低被黑客攻击的风险, 提高账户安全 性。
由上可以看出, 本发明提供的方法实施例中的智能密钥设备还具有签名功能, 即在一 个设备上集成了数字签名功能和动态口令牌功能, 且针对二代 USBkey而言, 不需要增加 USB key的体积, 也不改变产品结构, 只需增加一个口令生成芯片, 就实现了动态口令功 能; 由于动态口令的生成芯片的价格便宜, 合理控制了集成了动态口令牌的二代 USB key 的硬件成本, 且数字签名功能和动态口令牌功能的设备能够共用显示装置, 结构设计简单 精巧。
