Britain’s Digital Surveillance: Hiding from Her Majesty’s “Black Boxes”英国的数字监控:隐藏从陛下的“黑盒子” Saturday, November 8th, 2008 星期六, 2008年11月八日 By Christopher Parsons |由克里斯托弗帕森斯| http://www.christopher-parsons.com There are plans to deploy ‘black boxes’ in UK ISPs’ networking hubs so that the government can capture and record every website that UK citizens visit.有计划部署'黑匣子'在英国互联网服务提供商的网络中心,以便政府能够捕捉和记录每一个网站,英国公民的访问。 A similar operation is in full swing in the United States, where the NSA has hooked up their own ‘black boxes’ to American Internet Service Providers’ (ISPs) networks to capture ‘questionable content’ passing through these networks.类似的行动是在全速在美国,那里的国家安全局已经上瘾了自己的'黑匣子'的美国因特网服务提供商'商( ISP )的网络捕获'问题的内容,通过这些网络。 Unlike the Americans, who only examine questionable content, the UK government is planning to develop a database to hold the contents of all messages passing along their nations’ telecommunications networks.不同的是美国人,谁只审查有问题的内容,英国政府正计划建立一个数据库进行内容的所有邮件传递自己的国家'的电信网络。 While this issue has recently been sensationalized in the media, I have yet to find a source addressing the actual technologies that will (likely) drive these ‘black boxes’.虽然这个问题最近被耸人听闻的媒体,我还没有找到一个来源解决实际技术,将(可能)驱动这些'黑盒子' 。 I want to address that deficiency, calling attention to the Deep Packet Inspection (DPI) technologies that will presumably be responsible for examining, categorizing, and heuristically evaluating the data flowing across British ISPs’ networks.我想解决这一不足,要求注意深度包检测(新闻部)技术,大概是负责审查,分类,评价和启发式的数据流在英国互联网服务供应商网络。 In this piece, I want to briefly explain how DPI technology works, its technical limitations, and modes of actively evading its surveillance powers.在这一块,我想简略地解释如何部技术工程,其技术的局限性,并积极方式逃避监督的权力。 Evading DPI-enabled surveillance is essential to participate in free, unsurveyed discourse in the contemporary digital environments that Western citizens find themselves within.规避部启用监视是必不可少的参与自由, unsurveyed话语在当代数字化环境下,西方公民发现自己内。 DPI Technologies 新闻部的技术 ISPs are uniquely situated to survey all of the data traffic that their customers are involved in. ISPs, unlike Google, Yahoo!, or Microsoft, act as gateways that individuals must pass through to access the Internet-at-large.互联网服务供应商的独特位于来调查的所有数据流量,他们的客户都参与进来的ISP不同,谷歌,雅虎,或微软,作为网关,个人必须通过接入互联网,在逃。 Thus, any attempt to comprehensively survey an individual’s online activities must occur at the ISP-level.因此,任何企图全面调查个人的网上活动必须在ISP的水平。 While simultaneously monitoring millions of customers might seem a Herculean task, or one firmly situated in the realm of science fiction, networking hardware vendors such as Cisco, L-1, Ellacoya Networks, and Procera Networks have risen to the challenge, producing devices that can survey, filter, alter, and censor content in real time, as it passes through ISPs’ networks.同时监测数以百万计的用户可能似乎是一项艰巨的任务,或一个坚定地坐落在境界科幻小说,网络硬件制造商如思科公司, L - 1时,提供商Ellacoya网络和叶兰网络已经上升到挑战,生产设备,可调查显示,过滤器,改变和内容进行检查实时,因为它通过互联网服务供应商网络。 Packets of data traversing the Internet are composed of two parts: a header and a payload.数据包穿越因特网两部分组成:标头和有效载荷。 The header holds the general addressing information – where the packet is going, what order it should arrive at its destination in, and so on.标题持有的一般处理信息-在分组会,什么顺序应该到达目的地的,等等。 The payload holds information about the application that sent the packet, as well as the particular contents of the packet itself – in the case of email, each packet holds the address that it should be delivered to, a bit of information that notes that an email application sent the packet, and some of the email’s text.持有有效载荷有关的应用程序发送数据包,以及特别是内容的数据包本身-的情况的电子邮件,每包拥有的地址,应当交付给一个位的资料指出,电子邮件应用程序发送数据包,以及一些电子邮件的文字。 Metaphorically, a packet can be thought of in the terms of postal mail: the header corresponds with the address on the outside of the envelope, and the payload the letter itself.比喻,一包可以被认为是条件的邮政邮箱:标题对应的地址以外的信封,和有效载荷的信本身。 DPI equipment lets ISPs examine the header information as well as the payload.新闻部的设备让互联网服务供应商审查标题信息以及有效载荷。 This means that ISPs can examine the text of email, instant messages, cellular phone text messages, and unencrypted Voice over Internet Protocol (VoIP) communications, in real time, as these messages are transmitted.这意味着,互联网服务供应商可以检查的文本电子邮件,即时信息,手机短信,并加密互联网语音协议( VoIP )通讯,实时,因为这些邮件的传播。 Given the present state of available networking equipment that the world’s networking vendors have made available to the market, I strongly expect that the UK government’s ‘Black Boxes’ are, in essence, DPI devices that capture data as it moves across UK ISPs’ networks, and will transmit the contents of those packets to government databases while analyzing packets’ contents to identify if they are carrying ‘questionable’ payloads.鉴于目前的状况提供网络设备,世界上的网络供应商提供了市场,我强烈希望英国政府的'黑匣子'是在本质上,新闻部设备,收集数据,因为它在英国的举动互联网服务供应商网络,并会转交的内容,这些数据包,而政府的数据库,分析数据包的内容确定,如果他们携带'可疑'的有效载荷。 The Effectiveness of DPI 的有效性新闻部 The Internet Evolution actually tested DPI equipment provided by Ellacoya and Ipoque earlier this year.互联网进化实际测试新闻部提供的设备提供商Ellacoya和Ipoque今年早些时候。 In their tests, they found that these vendors’ devices could not filter ‘unwanted’ content 100% of the time – the applications targeted by the devices continued to function, although at reduced speeds, in spite of the censoring and filtering heuristics that the devices employ.在他们的试验,他们发现,这些厂商的设备无法过滤器'不想要'的内容100 %的时间-应用目标的设备继续发挥作用,但减少的速度,尽管审查和过滤启发式的装置雇用。 This suggests that attempting to capture unencrypted Voice over Internet Protocol conversations, as an example, will never be fully successful because some packets associated with a conversation will not be correctly identified, captured, and saved in meaningful ways by the UK government’s ‘black boxes’.这表明,试图捕获未加密的互联网协议语音交谈,作为一个例子,将永远不会完全成功,因为一些相关的数据包的谈话不会被正确识别,捕获和储存在有意义的方式由英国政府的'黑色盒子' 。 Moreover, and pertaining to the following section, the tests that the Internet Evolution performed suggest that data-encryption strategies can prevent the capture and filtering of data traffic.此外,有关下面一节,测试,互联网演进表现表明,数据加密战略,可以防止捕获和过滤的数据流量。 Evading DPI Surveillance 规避部监视 It seems that every day we hear about a new data scandal in the UK; some new database is accidentally leaked, putting the information of hundreds, thousands, or millions of UK citizens at risk of being used for nefarious purposes.看来,我们每天都听到一个新的数据丑闻在英国,一些新的数据库是意外泄露,使信息的几百人,几千,或数以百万计的英国公民有可能被用于邪恶目的。 The suggestion that all citizens’ digitized conversations and online actions be captured and stored by the UK government only heightens worries: what will happen when (not if) this proposed database is breached?有人建议,所有公民的数字化和网络会话的行动被抓获,并储存在英国政府不仅加剧的担忧:会发生什么事时, (如果不是)这一提议的数据库是违背? How much information will be accessible to criminals?多少信息将被犯罪分子利用? Fortunately, UK citizens can prevent their government’s DPI equipment from ever capturing conversations or online actions, and thus simultaneously limit exposure to the risks of identity theft and ubiquitous government surveillance.幸运的是,英国公民可以防止其政府新闻部设备从以往任何时候都捕捉对话或者在线行动,因此,同时限制暴露于风险的身份盗窃和无处不在政府的监视。 A core weakness of DPI equipment is that it cannot read the contents of fully encrypted communications.一个核心的弱点新闻部的设备,它不能阅读的内容完全加密通讯。 This means that when you send or receive encrypted data packets that the government’s devices will be unable to capture the contents of your email, your VoIP sessions, or your instant messages.这意味着,当你发送或接收加密的数据包,政府的设备将无法获取您的电子邮件内容,您的VoIP会议,或您的即时消息。 Encryption isn’t something that is terribly hard to set up; Voltage Security has a product that will let Windows users encrypt their sent email at a low annual cost.加密是不是一件可怕的是难以成立;电压安全的产品,让Windows用户加密他们发送电子邮件低年度费用。 By default, Skype encrypts its data traffic to prevent surreptitious snooping of your private conversations, actually providing more privacy than talking on the phone.默认情况下, Skype的加密的数据流量,以防止秘密窥探你的私人谈话,实际上提供了更多的隐私比讲电话。 When it turns to instant messaging, there are several open source clients such as Trillian (for Windows) and Adium (for OS X and Linux) that have built-in encryption and compatibility with all major messaging services.当它转向即时消息,有几个开源的客户如Trillian (适用于Windows )和Adium (对OS X和Linux )具有内置的加密和兼容性与所有主要的信息服务。 Finally, when browsing websites, access the ‘https’ versions of the sites whenever possible to encrypt data traffic to and from the websites.最后,当浏览网站,进入' HTTPS的'版本的网站只要有可能对数据进行加密的流量和网站。 Why Hide from Her Majesty? 为什么要隐藏从陛下? You may be asking: why should I bother with this encryption nonsense?您可能会问:我为什么要费心与此加密胡说? I don’t have anything to hide – as a law-abiding citizen I find it offensive, but not necessary ‘dangerous’, that my government is snooping on me.我没有隐藏任何东西-作为一个守法的公民我觉得进攻,但没有必要'危险' ,我国政府正在对探听我。 Only criminals have something to hide!只有罪犯隐藏的东西! The collection and centralization of large amounts of personal data gives criminals a single point that they can attack to access to vast swathes of information about law-abiding citizens.收集和集中大量的个人资料给犯罪分子一个单点,他们可以攻击获得大片资讯守法的公民。 As the UK government persistently demonstrates, it cannot be trusted to secure the citizen data that it holds.由于英国政府坚持表明,它不能信任,以确保公民的数据,它拥有。 By continuing to predominantly send unencrypted messages, you greatly enhance the chances that your personal information could be used to open lines of credit, create phony identification documents, and generally cause mischief in your good name.继续发送未加密的主要信息,大大提高您的机会,你的个人信息可能被用来打开信贷额度,建立假证件,一般事业恶作剧在您的好名声。 Encrypting your data, hiding your personal thoughts and communications from the proposed UK ‘black boxes’, is essential to prevent your identity being stolen, and ensures that you can continue to engage in free speech without worrying feeling the chilling effects of persistent government surveillance.加密您的数据,隐藏您的个人想法和通信由英国提出的'黑匣子' ,是至关重要的,以防止您的身份被盗,并确保您可以继续从事自由言论,而不用担心冷的感觉持续影响政府的监视。 Protecting your communications isn’t about hiding because you’re a criminal: it’s about limiting criminals from taking advantage of your good name while protecting your enshrined right of free speech.保护您的通信是不是隐藏,因为你是一个刑事:它是限制犯罪分子利用你的好名声,同时保护您的体现言论自由的权利。 Have Your Say: Britain’s Digital Surveillance: Hiding from Her Majesty’s “Black Boxes” 你说:英国的数字监控:隐藏从陛下的“黑盒子” Please read our请仔细阅读我们的 posting guidelines before posting张贴在发布前的指导方针 . 。 Alternatively或者 you can discuss this report here你可以讨论这份报告在这里 . 。 2 Responses to “Britain’s Digital Surveillance: Hiding from Her Majesty’s “Black Boxes””第2响应“英国的数字监控:隐藏从陛下的”黑盒子“ ”

Its not just Governments that are abusing private communication data.它不只是政府滥用私人通信的数据。
The other good reason for encrypting and obfuscating your communications is the emerging threat of systems like Phorm / BT Webwise to monitor your communications for marketing.其他很好的理由加密和混淆你的通讯是新出现的威胁的系统,如Phorm /电信Webwise监控您的通信市场。
Currently, as a web site operator or user of a web site, you cannot trust BT to respect the privacy/confidentiality of your communications (and the UK Government/regulators/police have done nothing to enforce communication privacy law).目前,作为一个网站运营商或用户的一个网站,你可以不相信英国电信,尊重隐私/机密性的通信(和英国政府/监管/警察没有采取任何强制执行通信隐私法) 。
BT have trialled this system twice already, profiling tens if not hundreds of thousands of people in 2006/7.英国电信已经试行这一制度已经两次,貌相如果不是几万几十万人在2006年/ 7 。
The visitors to this site, for example, could be profiled and targeted with ‘relevant’ advertising by BT.游客到本网站,例如,可异形和有针对性的相关广告由BT 。
Because its not encrypted BT consider that they have your consent to have your communication intercepted, your creative work copied and sold, and your visitors stripped.因为它没有加密英国电信公司认为,他们有您的同意,让您的通讯拦截,您的创造性劳动复制和销售,以及访问者取消。
The use of communication data for marketing is a gross privacy intrusion, its mass industrial espionage, and systematic copyright violation.使用通信数据的营销是一个严重的隐私入侵,其大规模工业间谍活动,并有系统地侵犯版权。
