具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅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，都属于本申请保护的范围。
以下结合附图，详细说明本申请实施例提供的技术方案。
在移动终端中包含有执行环境(Execution Environment)，是存在于移动设备中的软硬件集合，能够为应用程序在移动设备中的运行提供必要的能力支持，一般包括硬件处理单元、易失性存储单元、非易失性存储单元、操作系统、调用接口等组件。执行环境可以为富执行环境(Rich Execution Environment)或者可信执行环境(Trusted Execution Environment)。富执行环境是运行在移动设备中的开放执行环境，为运行其中的应用程序提供开放、丰富的运行能力支持，但安全保护能力相对较弱。可信执行环境是运行在移动设备中的隔离执行环境，相对于富执行环境，具备较强的安全能力，以确保运行其中的应用程序、敏感数据等在相对可信的环境中得到存储、处理和保护。
执行环境中可以运行或安装有移动应用，例如可以至少包含移动应用A和移动应用B。在安装有安全芯片的移动终端，通过在安全芯片中安装安全应用，提高移动终端设备的安全性。
在现有技术中，对于提供安全芯片的移动终端，各个移动应用的开发者，需要在 安全芯片中安装独立的安全应用，例如在华为手机中，淘宝、苏宁、京东为了提高其移动应用的安全性，需要分别在安全芯片中安装针对自身的安全应用，从而导致不必要的研发支出，也不利于后期的维护。尤其是对于同一个开发方或者关联的开发方开发多个移动应用的情况，例如淘宝、咸鱼、支付宝等移动应用，在安全需求统一的情况下，完全没有单独开发若干个独立的安全应用。
为了解决该技术问题，可以通过在手机中共享安全应用的方式来实现，该安全应用可以预置或者后期下载到用户的手机中，使用该安全应用管理各个移动应用的密钥，并实现对业务数据的处理，从而实现了使用一个安全应用为多个移动应用提供安全服务，从而实现了安全应用的共享。
为了便于描述，本申请以两个移动应用为例进行说明，例如移动应用A为淘宝移动应用，移动应用B为苏宁移动应用。需要说明的是，安全应用对于各个移动应用可以按照相同的方式进行管理，各个移动应用的通信安全保护密钥和业务密钥在安全应用中被安全隔离，每个移动应用在向安全应用请求服务时，只能访问该移动应用对应的通信安全保护密钥和业务密钥。
第一实施例
本申请实施例提供的共享安全应用的方法如图1所示，包括以下步骤：
步骤105，移动应用接收移动应用的通信安全保护密钥；安全通信保护密钥可以由移动应用的管理服务器生成，也可以由安全应用的管理服务器生成，然后同步给移动应用的管理服务器；移动应用(例如移动应用A和移动应用B)可以分别从对应的移动应用服务器(例如移动应用A的服务器和移动应用B的服务器)接收各自的通信安全保护密钥(例如移动应用A的通信安全保护密钥和移动应用B的通信安全保护密钥)；通信安全保护密钥可以是对称密钥，也可以是非对称密钥；通信安全保护密钥是对称密钥的情况下，通信安全保护密钥主要用于待传输的业务数据进行加密或者解密；通信安全保护密钥是非对称密钥的情况下，通信安全保护密钥中的公钥主要用于待传输的业务数据进行加密和对返回的签名进行验证，通信安全保护密钥中的私钥主要对接收到的加密后的业务数据进行解密，并利用业务密钥处理后，对处理后的业务数据进行签名；一般而言，通信安全保护密钥的公钥可以保存在移动应用中，通信安全保护密钥的私钥保存在安全应用中；
步骤110，安全应用接收移动应用的通信安全保护密钥和业务密钥；如上所述，安 全通信保护密钥可以由移动应用的管理服务器生成，也可以由安全应用的管理服务器生成，然后同步给移动应用的管理服务器；在移动应用的通信安全保护密钥由移动应用的管理服务器生成的情况，可以在安全应用的管理服务器接收到移动应用的通信安全保护密钥后发送给安全应用；移动应用(例如移动应用A和移动应用B)的业务密钥由移动应用的管理服务器生成，然后移动应用的管理服务器将移动应用的业务密钥(例如移动应用A的业务密钥和移动应用B的业务密钥)发送至安全应用的管理服务器；安全应用可以从安全应用的管理服务器接收移动应用的通信安全保护密钥和业务密钥(例如移动应用A的通信安全保护密钥和业务密钥，以及移动应用B的通信安全保护密钥和业务密钥)；安全应用可以将接收的各个移动应用的通信安全保护密钥和/或业务密钥进行安全隔离，例如将移动应用A的通信安全保护密钥和业务密钥和移动应用B的通信安全保护密钥和业务密钥进行安全隔离，可以通过将通信安全保护密钥和业务密钥分别存储在不同的文件中，可以每个文件只存储一个密钥，或者每个文件存储一个移动应用对应的通信安全保护密钥和业务密钥，通过设置各个移动应用的访问权限，从而实现了密钥的安全隔离。需要说明的是，通信安全保护密钥采用非对称密钥时，各个移动应用可以采用相同的公钥作为，而安全应用可以采用对应的私钥作为通信安全保护密钥；移动应用的业务密钥可以有多个，例如既有对称密钥作为业务密钥，又有非对称密钥作为业务密钥，可以针对不同的业务使用不同的业务密钥，例如视频业务使用对称密钥来处理，语音业务使用非对称密钥来处理。
步骤115，移动应用使用移动应用的通信安全保护密钥将业务数据加密后发送至安全应用；移动应用本身有业务数据需要解密的情况下，由于移动应用本身不具有业务密钥，所以移动应用需要请求安全应用来对业务数据进行解密。为了提高安全性，在移动应用请求安全应用对业务数据进行解密时，可以使用移动应用的通信安全保护密钥对业务数据进行加密；一般而言，移动应用的通信安全保护密钥采用非对称密钥，例如移动应用所保存的密钥为公钥，安全应用所保存的密钥为私钥。移动应用(例如移动应用A和移动应用B)使用自身的公钥(例如移动应用A的通信安全保护公钥和移动应用B的通信安全保护公钥)对业务数据进行加密，并发送至安全应用；非对称密钥的算法可以包括RSA、Elgamal、背包算法、Rabin、D-H、ECC中的任一种；
步骤120，安全应用使用移动应用的通信安全保护密钥解密以得到业务数据；安全应用从安全应用的管理服务器接收移动应用的移动通信安全保护密钥(例如移动应用A的通信安全保护私钥和移动应用B的通信安全保护私钥)，从而可以使用移动应用的移动通信安全保护密钥来对接收的数据进行解密，得到业务数据；
步骤125，安全应用使用移动应用的业务密钥处理业务数据；安全应用可以使用自身存储的业务密钥(例如移动应用A的业务密钥和移动应用B的业务密钥)对业务数据进行处理；业务密钥可以为对称密钥或者非对称密钥，对称密钥的算法可以包括DES、AES、以及MD5中的任一种，非对称密钥的算法可以包括RSA、Elgamal、背包算法、Rabin、D-H、ECC中的任一种。在使用非对称密钥作为业务密钥时，业务数据的处理方式可以根据具体的需求来确定，例如业务数据需要加密，则可以使用业务密钥的公钥进行加密，业务数据本身是加密数据，则可以使用业务密钥的私钥进行解密；此外，处理方式还可以包括对业务数据进行签名或者验证业务数据的签名；例如业务数据本身是包含签名的数据，则可以使用业务密钥的公钥来验证该签名，如果业务数据需要进行签名，则可以使用业务密钥的私钥来进行签名。在使用对称密钥时，业如果业务数据需要加密，则可以使用业务密钥进行加密，业务数据本身是加密数据，则可以使用业务密钥进行解密。可以理解的是，业务密钥可以有多组，例如多组非对称密钥而言，安全应用可以保存有不同密钥对中的公钥或者私钥，并根据具体的业务需求使用相应的密钥。
步骤130，安全应用将处理后的业务数据发送至移动应用。安全应用在将业务数据处理后，可以将处理后的业务数据发送至对应移动应用，例如将处理后的移动应用A的业务数据发送至移动应用A，将处理后的移动应用B的业务数据发送至移动应用B；随后移动应用A和移动应用B可以根据处理后的业务数据进行后续的业务流程。
可选地，安全应用在向移动应用发送处理后的业务数据时，还可以使用移动应用的通信安全保护密钥(例如移动应用A的通信安全保护私钥和移动应用B的通信安全保护私钥)来对处理后的业务数据签名，进一步提高安全性。
上述的实施例，能够实现由安全应用对若干移动应用的通信安全保护密钥和业务密钥的统一管理，从而实现安全应用的共享，避免针对每个移动应用在安全芯片中安装各自的安全应用。
需要说明的是，如果通信安全保护密钥和业务密钥均由移动应用的管理服务器，则移动应用的管理服务器生成通信安全保护密钥和业务密钥并无先后次序的限制，可以先生成通信安全保护密钥，也可以先生成业务密钥，也可以同时生成通信安全保护密钥和业务密钥；同样地，向安全应用管理服务器发送通信安全保护密钥和业务密钥时，业务先后次序的限制，可以先发送通信安全保护密钥，也可以先发送业务密钥，也可以同时发送信安全保护密钥和业务密钥。
进一步地需要说明的是，可以不由移动应用的管理服务器或安全应用的管理服务 器生成通信安全保护密钥，因而本实施例中与安全通信保护密钥相关的步骤可以省略。
第二实施例
本申请实施例提供的共享安全应用的方法如图2所示，包括以下步骤：
步骤205，安全应用接收移动应用的通信安全保护密钥和业务密钥；安全通信保护密钥可以由移动应用的管理服务器生成，也可以由安全应用的管理服务器生成，然后同步给移动应用的管理服务器；在移动应用的通信安全保护密钥由移动应用的管理服务器生成的情况，可以在安全应用的管理服务器接收到移动应用的通信安全保护密钥后发送给安全应用；移动应用(例如移动应用A和移动应用B)的业务密钥由移动应用的管理服务器生成，然后移动应用的管理服务器将移动应用的业务密钥(例如移动应用A的业务密钥和移动应用B的业务密钥)发送至安全应用的管理服务器；安全应用可以从安全应用的管理服务器接收移动应用的通信安全保护密钥和业务密钥(例如移动应用A的通信安全保护密钥和业务密钥，以及移动应用B的通信安全保护密钥和业务密钥)；通信安全保护密钥可以是对称密钥，也可以是非对称密钥；通信安全保护密钥是对称密钥的情况下，通信安全保护密钥主要用于待传输的业务数据进行加密或者解密；通信安全保护密钥是非对称密钥的情况下，通信安全保护密钥中的公钥主要用于待传输的业务数据进行加密和对返回的签名进行验证，通信安全保护密钥中的私钥主要对接收到的加密后的业务数据进行解密，并利用业务密钥处理后，对处理后的业务数据进行签名；一般而言，通信安全保护密钥的公钥可以保存在移动应用中，通信安全保护密钥的私钥保存在安全应用中；
步骤210，移动应用接收移动应用的通信安全保护密钥；如上所述，安全通信保护密钥可以由移动应用的管理服务器生成，也可以由安全应用的管理服务器生成，然后同步给移动应用的管理服务器；移动应用(例如移动应用A和移动应用B)可以分别从对应的移动应用服务器(例如移动应用A的服务器和移动应用B的服务器)接收各自的通信安全保护密钥(例如移动应用A的通信安全保护密钥和移动应用B的通信安全保护密钥)；需要说明的是，通信安全保护密钥采用非对称密钥时，各个移动应用可以采用相同的公钥作为，而安全应用可以采用对应的私钥作为通信安全保护密钥；移动应用的业务密钥可以有多个，例如既有对称密钥作为业务密钥，又有非对称密钥作为业务密钥，可以针对不同的业务使用不同的业务密钥，例如视频业务使用对称密钥来处理，语音业务使用非对称密钥来处理。
步骤215，移动应用使用移动应用的通信安全保护密钥将业务数据加密后发送至安 全应用；移动应用本身有业务数据需要解密的情况下，由于移动应用本身不具有业务密钥，所以移动应用需要请求安全应用来对业务数据进行解密。为了提高安全性，在移动应用请求安全应用对业务数据进行解密时，可以使用移动应用的通信安全保护密钥对业务数据进行加密；一般而言，移动应用的通信安全保护密钥采用非对称密钥，例如移动应用所保存的密钥为公钥，安全应用所保存的密钥为私钥。移动应用(例如移动应用A和移动应用B)使用自身的公钥(例如移动应用A的通信安全保护公钥和移动应用B的通信安全保护公钥)对业务数据进行加密，并发送至安全应用；非对称密钥的算法可以包括RSA、Elgamal、背包算法、Rabin、D-H、ECC中的任一种；
步骤220，安全应用使用移动应用的通信安全保护密钥解密以得到业务数据；安全应用从安全应用的管理服务器接收移动应用的移动通信安全保护密钥(例如移动应用A的通信安全保护私钥和移动应用B的通信安全保护私钥)，从而可以使用移动应用的移动通信安全保护密钥来对接收的数据进行解密，得到业务数据；
步骤225，安全应用使用移动应用的业务密钥处理业务数据；安全应用可以使用自身存储的业务密钥(例如移动应用A的业务密钥和移动应用B的业务密钥)对业务数据进行解密；业务密钥可以为对称密钥或者非对称密钥，对称密钥的算法可以包括DES、AES、以及MD5中的任一种，非对称密钥的算法可以包括RSA、Elgamal、背包算法、Rabin、D-H、ECC中的任一种；在使用非对称密钥作为业务密钥时，业务数据的处理方式可以根据具体的需求来确定，例如业务数据需要加密，则可以使用业务密钥的公钥进行加密，业务数据本身是加密数据，则可以使用业务密钥的私钥进行解密；此外，处理方式还可以包括对业务数据进行签名或者验证业务数据的签名；例如业务数据本身是包含签名的数据，则可以使用业务密钥的公钥来验证该签名，如果业务数据需要进行签名，则可以使用业务密钥的私钥来进行签名。在使用对称密钥时，业如果业务数据需要加密，则可以使用业务密钥进行加密，业务数据本身是加密数据，则可以使用业务密钥进行解密。
步骤230，安全应用将处理后的业务数据发送至移动应用。安全应用在将业务数据处理后，可以将处理后的业务数据发送至对应移动应用，例如将处理后的移动应用A的业务数据发送至移动应用A，将处理后的移动应用B的业务数据发送至移动应用B；随后移动应用A和移动应用B可以根据处理后的业务数据进行后续的业务流程。
需要说明的是，如果通信安全保护密钥和业务密钥均由移动应用的管理服务器，则移动应用的管理服务器生成通信安全保护密钥和业务密钥并无先后次序的限制，可以 先生成通信安全保护密钥，也可以先生成业务密钥，也可以同时生成通信安全保护密钥和业务密钥；同样地，向安全应用管理服务器发送通信安全保护密钥和业务密钥时，业务先后次序的限制，可以先发送通信安全保护密钥，也可以先发送业务密钥，也可以同时发送信安全保护密钥和业务密钥。
进一步地需要说明的是，可以不由移动应用的管理服务器或安全应用的管理服务器生成通信安全保护密钥，因而本实施例中与安全通信保护密钥相关的步骤可以省略。
此外，安全应用可以包括第一安全应用和第二安全应用，一部分移动应用于第一安全应用通信，另一部分移动应用与第二安全应用通信。优选地，移动应用还可以通过安全代理与安全应用通信。
可选地，安全应用在向移动应用发送处理后的业务数据时，还可以使用移动应用的通信安全保护密钥(例如移动应用A的通信安全保护私钥和移动应用B的通信安全保护私钥)来对处理后的业务数据签名，进一步提高安全性。

上述系统，可以完成通信安全保护密钥和业务密钥的分发，从而使得可信执行环境中的若干移动应用共享一个管理应用得以实现。
第十一实施例
如图11所示，本申请实施例提供的共享安全应用的系统包括移动终端、移动应用的管理服务器和安全应用的管理服务器。移动终端包括富执行环境、可信执行环境和安全芯片。富执行环境为运行在移动设备中的开放执行环境，为运行其中的应用程序提供开放、丰富的运行能力支持，但安全保护能力相对较弱。可信执行环境为运行在移动设备中的隔离执行环境，相对于富执行环境，具备较强的安全能力，以确保运行其中的应用程序、敏感数据等在相对可信的环境中得到存储、处理和保护。
移动应用的管理服务器可以生成移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥和业务密钥，移动应用的管理服务器 可以将移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥和业务密钥发送至安全应用的管理服务器，并将移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥发送至相应的移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)。安全应用的管理服务器可以将移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥和业务密钥发送至安全应用，安全应用在收到移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥和业务密钥以后，会将移动应用的通信安全保护密钥和业务密钥进行安全隔离，例如将移动应用A的通信安全保护密钥和业务密钥与移动应用B的通信安全保护密钥和业务密钥进行隔离。需要说明的是，如果通信安全保护密钥由安全应用的管理服务器提供，则各个移动应用可以保存相同的公钥，而安全应用保存对应的私钥；如果通信安全保护密钥由移动应用的管理服务器提供，则各个移动应用的公钥不同，并且安全应用存储与多个对应的公钥对应的私钥；或者如果通信安全保护密钥由移动应用的管理服务器提供，在使用对称密钥的情况下，各个移动应用保存的自身的密钥，并且安全应用保存对应的密钥。安全应用中需要对各个通信安全保护密钥进行安全隔离。各个移动应用对应的业务密钥一般不同，各个业务密钥之间也需要隔离。
可选地，移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥也可由安全应用的管理服务器生成。安全应用的管理服务器可以将其生成的移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥发送至移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的管理服务器。在这种情况下，移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的管理服务器可以仅生成移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的业务密钥，并将生成的移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的业务密钥发送至安全应用的管理服务器。安全应用的管理服务器可以将移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥和业务密钥发送至安全密钥，移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的管理服务器可以将移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护密钥发送至相应的移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)。
一般而言，移动应用的通信安全保护密钥采用非对称密钥，例如移动应用所保存 的密钥为公钥，安全应用所保存的密钥为私钥。非对称密钥的算法可以包括RSA、Elgamal、背包算法、Rabin、D-H、ECC中的任一种。
在移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)发起业务操作请求时，例如解密操作请求，可以使用移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)所保存的通信安全保护公钥对业务数据进行加密，并将加密后的业务数据发送到安全应用。可选地，移动应用还可以发起加密的操作请求，请求安全应用对业务数据加密。在使用非对称密钥作为业务密钥的情况下，还可以发起请求签名或者验证签名的操作请求。
安全应用在收到移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)使用移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护公钥加密的业务数据以后，可以使用移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护私钥解密，得到业务数据。随后，安全应用可以使用移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的业务密钥对业务数据进行解密，并可以将解密后的业务数据发送至移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)，移动应用可以随后使用解密后的业务数据完成后续的业务流程。业务密钥可以为对称密钥或者非对称密钥，对称密钥的算法可以包括DES、AES、以及MD5中的任一种，非对称密钥的算法可以包括RSA、Elgamal、背包算法、Rabin、D-H、ECC中的任一种。
可选地，安全应用在使用移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的业务密钥对业务数据进行解密后，还可以使用移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)的通信安全保护私钥对解密后的业务数据进行签名，并发送给移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)，移动应用(例如富执行环境中的移动应用A和可信执行环境中的移动应用B)可以使用对应的通信安全保护公钥进行验证签名，得到解密后的业务数据。
上述系统，可以完成通信安全保护密钥和业务密钥的分发，从而使得可信执行环境中的若干移动应用共享一个管理应用得以实现。
