Counter mode is slightly better suited than CBC for encrypting UDP traffic.One advantage of counter mode over OFB and other modes that simulate stream ciphers is that it can inherently survive data loss—the current state of the counter can be passed in the clear each time a packet is sent.Another major advantage of counter mode is that it allows for parallelization,which is not supported by any of the default modes,except for ECB (a CBC-based approach could parallelize at the packet level,but could not parallelize the processing of data within a single packet).Another feature unique to OFB is that most of the work can be done offline.That is,you can generate a key stream before there is even data available to encrypt,while you have spare CPU cycles.Additionally,because counter mode essentially supports arbitrarily jumping around a data stream,it can enable file encryption where random access to the data is still possible.Moreover,in theory,counter mode should be able to handle the UDP encryption problem without a rekey for every packet.However,current limitations of the Open SSL library make that goal difficult to achieve,although the forthcoming 0.9.7 release will fix the problem.

计数器模式可能更适合稍微比CBC模式用于加密的UDP流量.对自主知识产权名牌之一,而其他模式模拟流密码计数器模式的优点是它可以生存本质的计数器数据丢失当前的状态可以在清澈的每一个数据包被发送的时间过去了.另一个反模式的主要优点是它的并行化,这是不以任何方式,除了默认的欧洲央行(一央行的方法可以在数据包级并行,支持允许,但不能在一个并行的数据处理单包).另一种功能独特的自主知识产权名牌的是,大部分的工作可以做离线.也就是说,你可以生成一个密钥流之前,甚至有数据可以加密,当你有多余的CPU周期.此外,由于计数器模式基本上支持任意跳来跳去一个数据流,它可以启用文件加密在随机访问的数据仍然是可能的.此外,在理论上,计数器模式应该能够处理没有为每个数据包的UDP加密密钥更新问题.然而,目前的限制SSL库开放使这一目标难以实现,尽管即将举行的0.9.7版本将解决这个问题.
