IE已经fix了.
用最新版firefox V38.01的可以很简单的fix.
Chrome和其他的不知道. 因为我基本不用.

发帖数: 3962 | 6 我也是局外人。让我来片面地描述一下。
Diffie和Hellman在1976年发表了他们的奠基性文章。Bob和Alice在Eve在场
的情况下，可以建立一个Bob和Alice共享的钥匙。他们还提出了认证的框架和
部分解。
在这个工作的启发下，Rivest，Shamir，和Adleman在1978年发表了RSA。
RSA很有用。但是理论基础不是很强。在1982年姚提出并解决了百万富翁问题。
加上他和Dolev在1981年的文章，姚建立了一个很严谨的密码学理论基础。当然
他在其它方面也有许多杰出贡献。
姚的图灵奖是在2000年，一人获奖。
Rivest，Shamir和Adleman的图灵奖是在2002年，三人分享。
Diffie和Hellman的图灵奖是在2015年，两人分享。 |

国际密码学领域的一场顶级智力较量
——西安电子科技大学胡予濮教授攻破GGH密码方案
■ 记者 秦明
一个原本有望成为国际密码学研究新技术的GGH密码映射方案，最近被西安电子科技大
学综合业务网理论及关键技术国家重点实验室的胡予濮教授攻破。胡予濮教授与他的博
士研究生贾惠文，对GGH映射本身以及基于GGH映射的各类高级密码应用进行了颠覆性的
否定。该研究成果——《GGH映射的密码分析》（Cryptanalysis of GGH Map），日前
经过同行专家的严格评审，已经被2016年欧洲密码年会（Eurocrypt 2016，简称欧密）
正式接收。这一会议和美洲密码年会（简称美密），被公认为密码学界最著名的两大国
际会议。2016年5月8日，胡予濮将赴奥地利维也纳，在欧密会上，正式向全世界的密码
同行报告这一突破性成果。

发帖数: 479 | 12 借你这个帖子冒个泡问个问题。
基于计算复杂度的密码算法是唯一的密码学的解决方案吗？ 现有的公开密钥的加密算
法或Diffie-Hellman, ElGamal算法，都是基于复杂问题来构建的，像是大素数乘积的
分解，离散对数，共轭问题，等等。正是由于解决这些问题的代数时间算法还没有公开
发表，所以这些算法还在使用。但是，因为没人能证明代数时间的解法不存在，这些算
法的安全性无法被直接证明，只能用复杂度来讨论。复杂度是建立在代数算法不存在的
基础上。如果代数算法被发现了，那复杂度就不存在了。因为这个原因，大家对传统密
码算法的忧虑一直存在，怕被破解。量子密钥才被用来替代传统密钥。
我想问一下，是不是存在一些不是基于复杂度的密钥交换方法？ECC应该算一个吧，基
于解的不确定性。我觉得ECC还是太烦了，可以更简单。如果简单的基于解的不确定的
算法还能被构造出来，量子密钥就没有必要了。我说的有理吗？

发帖数: 3794 | 21 目的：
破解只有80／443端口开放的网络的限制，使得其他的端口的程序能够正常使用，比如
ssh的22端口，ftp端口，mitbbs的web radio：8000端口。
硬件要求：
1。能够刷tomato firmware的路由器
2。路由器用了dyndns注册了域名
3。路由器启动了openvpn server功能。
4。一个跑linux的笔记本
基本原理：
在路由器上启动vpn server服务，端口设在443上。
笔记本通过openvpn client，与路由器之间建立一个vpn安全连接，
所有的网络包都先转发到路由器上openvpn server。然后再上internet
因此，笔记本上能够用到的带宽，基本就是dsl路由器上传的带宽了。
一般dsl上传带宽就300－600kbps，不做大量下载，还够用。
vpn的认证方式有两种：static key和TLS，以下步骤是TLS用的，static key应该更简
单的。

发帖数: 35 | 27 看来大伙都很感兴趣，我也助助兴吧
这个算法本身的idea实际上很简单，向microbe等牛牛们
看两眼也就知道大体意思了，不过话又说会来了，很多东西
本来就是很简单的，比如RSA，简直就是费马定律的翻版
当年Ron Rivest从法国回来后看到diffie-Hellman的文章
灵机一动就和Shamir等发明了这一不可一世的算法
(据说英国情报系统早在71年左右就发明了这一算法，不过没有发表而已)
口一开就停不住了，咱们先从one-time-pad说起。 One-time-pad就是
接收双方首先互相确定一密码本，当然骇客不能知道。然后把数据和
密码本XOR后传过去。先农50年代证明这一算法是无法破译的。当然既然叫
one-time-pad就是说同一密码只能用一次，反复使用就很危险。Ron Rivest
的网络安全课上就有个作业是要你破译反复使用的one-time-pad，当然这是
题外话
先农证明的这个定律是没有任何assumption的，就是说不管你有无穷大的计算
能力和无穷大的存储空间都没法破译。就是所谓的information security。
