在我的游戏的Java服务器上，我运行'sudo yum update'，现在我在尝试通过我的游戏客户端连接时出现以下错误：

5天前，这是我从客户端连接到我的游戏服务器时所看到的：

我认为我的keystore.jks文件的证书已过期，但我甚至尝试使用startssl更新的证书进行更新，但无济于事。任何帮助都会非常感激。
理想情况下我想解决这个问题（所以我可以继续更新我的EC2服务器）。
修改
我使用以下命令在上次更新列表中找到了以下java更新： rpm -qa --last

答案 0 :(得分：7)
最初（即在您通过rpm更新系统之前），您使用了密码套件TLS_DH_anon_WITH_AES_128_CBC_SHA256，该套件没有适当的Diffie-Hellman密钥交换验证。 （注意：一种容易受到中间人攻击的协议）
根据Red Hat Customer Portal和Amazon Linux AMI Security Center）最近发布了关键 java-1.7.0-openjdk安全更新。由于这个问题，你肯定会遇到上述问题，如下所述：
在TLS协议组成Diffie-Hellman的方式中发现了一个缺陷 （DH）密钥交换。一个中间人攻击者可以使用这个漏洞 在密钥交换期间强制使用弱512位导出级密钥， 允许他们解密所有流量。 （CVE-2015-4000）
注意：此更新会强制OpenJDK中的TLS / SSL客户端实现 拒绝低于768位的DH密钥大小，这会阻止会话 降级为出口级密钥。请参阅Red Hat Bugzilla bug 1223211， 链接到“参考”部分，有关此内容的其他详细信息 变化
这解释了 - 至少在某种程度上 - 为什么您现在获得Cipher suite = SSL_NULL_WITH_NULL_NULL，因为您的系统上似乎不再提供原始密码套件（或者现在已经被禁用）。在您提供的输出中也支持Protocol = NONE。
＆＃39; Java Cryptography Architecture Oracle Providers Documentation for Java Platform Standard Edition 7＆＃39;概述文档的原始密码套件也位于默认禁用密码套件列表中。所以我认为OpenJDK实现确实解决了这个安全问题（见上面的URL引用）。
通常，Java的这个安全修复程序与所谓的Logjam attack相关，建议是：
确保您使用的任何TLS库都是最新的，您维护的服务器使用2048位或更大的素数，并且您维护的客户端拒绝小于1024位的Diffie-Hellman素数
作为解决方案的想法，也许您只需更改游戏应用程序（客户端和/或服务器）的SSL /加密设置即可使用非 - { {1}}密码套件？
在Oracle提供的文档中查看默认启用的密码套件，或者查看一个简单而有效的工具来检测@dolmen提供的Enabled ciphers on Ubuntu OpenJDK 7。
修改1：
看看这个StackOverflow post和answer by @EJP它看起来与你的StackTrace非常相似（*万岁！）。看来你好多了......
请勿使用启用的密码套件。取出代码并重新测试。您已经启用了匿名套件，通过它们无论如何都无法进行身份验证。
因此，您可能会将代码更改为不显式使用DH-anon，因为它会启用默认情况下未启用的密码套件（＆＃34; DH-anon＆＃34; ...）。如上所述，如果您取出这些代码行，请尝试检查结果是什么。
也许选择setEnabledCipherSuites(..)作为密码套件（这里没有经典的DH参数）。但是，因此您应该在服务器端更新为OpenJDK 8或Oracle JRE / JDK 8，因为这在OpenJDK 7中不可用（请参阅服务器调试日志输出）。
希望，这有帮助。
