本发明实施例提供一种语音加密的测试方法及测试设备，可以准确检测终端是否具备语音加密功能。以下分别进行详细说明。
为了更好的理解本发明实施例，下面先对本发明实施例适用的一种系统架构进行描述。请参阅图1，图1是本发明实施例公开的一种系统架构示意图。如图1所示，包括测试设备和终端，其中，测试设备与终端可以通过有线连接（例如，通过终端上的耳机接口、USB接口与测试设备连接），也可以通过无线连接（例如，通过蓝牙连接、WiFi连接等），测试设备可以包括语音编解码模块、语音加解密模块、音频处理模块、数据收发模块等，语音编解码模块设置为对音频数据进行编码和解码，语音加解密模块设置为对音频数据进行加密和解密，音频处理模块可以进行录音，数据收发模块可以进行数据的发送和接收。终端可以包括手机、电脑、平板电脑等可以进行语音处理的设备。实施图1所示的系统架构，可以通过测试设备准确检测终端是否具备语音加密功能。
请参阅图2，图2是本发明实施例公开的一种语音加密的测试方法的流程示意图。如图2所示，本实施例中所描述的语音加密的测试方法，包括如下步骤。
201，测试设备将源语音数据包发送至终端，源语音数据包用于终端利用语音加密算法对源语音数据包进行加密并得到第一加密语音数据包，语音加密算法为测试设备与终端预先协商的。
本发明实施例中，源语音数据包可以是从测试设备实时获取的音频中提取的，例如，测试设备通过录音设备实时获取的一段录音，测试设备在网络上下载的一段语音等，将上述一段录音、一段语音经过模数转换，转换为数字信号，即可得到源语音数据包；源语音数据包也可以是测试设备预先存储的，例如，可以在测试设备的非易失性存储器中预先存储多个语音数据（例如，一段歌曲、一段手机铃声等），当测试设备需要发送源语音数据包时，从上述多个语音数据中随机抽取一个语音数据，将上述一个语音数据经过模数转换，得到数字信号，即可以得到源语音数据包。测试设备将源语音数据包发送至终端之后，终端利用语音加密算法对源语音数据包进行加密并得到第一加密语音数据包，其中，终端利用语音加密算法对源语音数据包（二进制数据流）进行处理，得到第一加密语音数据包（经过语音加密算法处理之后的二进制数据流）。上述语音加密算法为测试设备与终端共同支持的算法，即测试设备和终端必须有共同支持的同一种语音加密算法。其中，语音加密算法为测试设备与终端预先协商的。在执行步骤201之前，测试设备与终端预先协商可以预先协商一种测试设备和终端共同支持的语音加密算法，终端和测试设备以上述共同支持的语音加密算法分别进行语音加密。显然的，在执行步骤201之前，测试设备与终端需要建立连接，测试设备与终端可以通过有线连接（例如，通过终端上的耳机接口、USB接口与测试设备连接），也可以通过无线连接（例如，通过蓝牙连接、WiFi连接等）。
可选的，在执行步骤201之前，可以执行如下步骤：
获取源语音数据包，源语音数据包是从测试设备中的录音设备获取的语音数据中提取的，或者源语音数据包是从测试设备中预先存储的语音数据中提取的。
其中，源语音数据包可以是从测试设备中的录音设备获取的语音数据中提取的，例如，测试设备通过录音设备实时获取的一段录音，测试设备从上述一段录音中提取部分录音数据，将上述部分录音数据转换为数字信号，即可得到源语音数据包；源语音数据包也可以是从测试设备中预先存储的语音数据中提取的，例如，可以在测试设备的非易失性存储器中预先存储多个语音数据（例如，一段歌曲、一段手机铃声等），当测试设备需要发送源语音数据包时，从上述多个语音数据中随机抽取一个语音数据，从随机抽取的一个语音数据中提取部分语音数据，将上述部分语音数据转换为数字信号，即可得到源语音数据包。

204，测试设备验证第一加密语音数据包与第二加密语音数据包是否匹配。若是，执行步骤205，若否，执行步骤206。
本发明实施例中，当测试设备得到第一加密语音数据包与第二加密语音数据包之后，测试设备验证第一加密语音数据包与第二加密语音数据包是否匹配。其中，源语音数据包为二进制数据流，测试设备利用语音加密算法对源语音数据包（二进制数据流）进行处理，得到第二加密语音数据包（经过语音加密算法处理之后的二进制数据流）。测试设备验证第一加密语音数据包与第二加密语音数据包是否匹配，可以通过对比第一加密语音数据包（二进制数据流）与第二加密语音数据包（二进制数据流）中每个二进制数是否相同，当第一加密语音数据包（二进制数据流）与第二加密语音数据包（二进制数据流）中二进制数的相同比例达到预设阈值时，则判定第一加密语音数据包与第二加密语音数据包匹配，预设阈值可以为80%、85%、90%、95%等，由于数据包在终端和测试设备之间传输时，会出现丢包等情况，很多时候第一加密语音数据包与第二加密语音数据包不可能完全匹配，只需达到预设阈值即可认为通过语音加密测试。
205，测试设备确定终端通过语音加密测试。
206，测试设备确定终端没有通过语音加密测试。
本发明实施例中，测试设备发送源语音数据包给终端，终端和测试设备用协商的语音加密算法分别对源语音数据包进行加密，分别得到第一加密语音数据包和第二加密语音数据包，当测试设备验证第一加密语音数据包与第二加密语音数据包匹配时，则确定终端通过语音加密测试。实施图2所示的实施例，由测试设备提供源语音数据包进行测试，可以防止由于终端提供源语音数据包导致终端骗过测试设备，从而可以准确检测终端是否具备语音加密功能，提高测试结果的准确度。
请参阅图3，图3是本发明实施例公开的另一种语音加密的测试方法的流程示意图。如图3所示，本实施例中所描述的语音加密的测试方法，包括如下步骤。

306，测试设备接收第三方测试设备发送的第三加密语音数据包。
307，测试设备判断第三加密语音数据包与第一加密语音数据包或第二加密语音数据包是否匹配；若是，则执行步骤307，若否，则执行步骤308。
本发明实施例中，当测试设备得到第三加密语音数据包之后，测试设备判断第三加密语音数据包与第一加密语音数据包或第二加密语音数据包是否匹配。其中，源语音数据包为二进制数据流，测试设备利用语音加密算法对源语音数据包（二进制数据流）进行处理，得到第二加密语音数据包（经过语音加密算法处理之后的二进制数据流）。测试设备判断第三加密语音数据包与第一加密语音数据包或第二加密语音数据包是否匹配，可以通过对比第三加密语音数据包（二进制数据流）与第一加密语音数据包（二进制数据流）或第二加密语音数据包（二进制数据流）中每个二进制数是否相同，当第三加密语音数据包（二进制数据流）与第一加密语音数据包（二进制数据流）中二进制数的相同比例达到预设阈值，或者第三加密语音数据包（二进制数据流）与第二加密语音数据包（二进制数据流）中二进制数的相同比例达到预设阈值时，则判定第一加密语音数据包与第二加密语音数据包匹配，预设阈值可以为80%、85%、90%、95%等，由于数据包在终端和测试设备，测试设备与第三方测试设备之间传输时，会出现丢包等情况，很多时候第三加密语音数据包与第一加密语音数据包或第二加密语音数据包不可能完全匹配，只需达到预设阈值即可认为通过语音加密测试。实施本发明实施例，通过引进第三方测试设备，可以通过两个测试设备进行测试，当两个测试设备都通过测试时，才判定终端通过语音加密测试，可以进一步提高测试结果的准确性，从而可以更加准确检测终端是否具备语音加密功能。
