实现技术：

JSSE（Java Security Socket Extension ）

是Sun为了解决在Internet上的实现安全信息传输的解决方案。它实现了SSL和TSL（传输层安全）协议。在JSSE中包含了数据加密，服务器验证，消息完整性和客户端验证等技术。通过使用JSSE，可以在Client和Server之间通过TCP/IP协议安全地传输数据。

为了实现消息认证。

Server需要：

1）KeyStore: 其中保存服务端的私钥

2）Trust KeyStore:其中保存客户端的授权证书

Client需要：

1）KeyStore：其中保存客户端的私钥

2）Trust KeyStore：其中保存服务端的授权证书

使用Java自带的keytool命令，去生成这样信息文件：

1）生成服务端私钥，并且导入到服务端KeyStore文件中

2）根据私钥，导出服务端证书

3）将服务端证书，导入到客户端的Trust KeyStore中

采用同样的方法，生成客户端的私钥，客户端的证书，并且导入到服务端的Trust KeyStore中

1）keytool -genkey -alias clientkey -keystore kclient.keystore

2）keytool -export -alias clientkey -keystore kclient.keystore -file client.crt

3）keytool -import -alias clientkey -file client.crt -keystore tserver.keystore

启动Server

启动Client，发送信息。

Server接收如下：正确解密

返回Client信息，如下：

如此，就完成了服务端和客户端之间的基于身份认证的交互。

client采用kclient.keystore中的clientkey私钥进行数据加密，发送给server。

server采用tserver.keystore中的client.crt证书（包含了clientkey的公钥）对数据解密，如果解密成功，证明消息来自client，进行逻辑处理。

server采用kserver.keystore中的serverkey私钥进行数据加密，发送给client。

client采用tclient.keystore中的server.crt证书（包含了serverkey的公钥）对数据解密，如果解密成功，证明消息来自server，进行逻辑处理。

如果过程中，解密失败，那么证明消息来源错误。不进行逻辑处理。这样就完成了双向的身份认证。
