卫报:维基解密创始人称强奸指控是诽谤
http://www.sina.com.cn 2010年08月23日 14:56 新浪尚品
“维基解密”创始人朱利安-阿桑奇的支持者已指责美国情报部门是阿桑奇遭强奸
指控事件的幕后黑手。他们表示,在阿桑奇在网上公布驻阿美军77000件战争文件后,
他们就预计美国情报部门会对阿桑奇采取诽谤行动。
朱利安-阿桑奇8月21日晚成为阴谋论的主角。检察官在此之前撤消了以阿桑奇涉嫌
强奸和猥亵为由发出的逮捕令。斯德哥尔摩检察官办公室的一位发言人20日证实,已签
发了对阿桑奇的逮捕令,呼吁阿桑奇“联络警方以便就涉嫌的罪行进行对质。”瑞典《
快报》称,39岁的阿桑奇涉嫌两起罪行,一名斯德哥尔摩女子指控阿桑奇对其实施了猥
亵。另一名来自斯德哥尔摩以西恩雪平的妇女则指控阿桑奇强奸了她。
阿桑奇声称,他是一场诽谤运动的受害者,他在“维基解密”网站的推特网页上否
认了强奸指控,称这些指控是毫无根据的,在此刻提出这些指控“令人深感不安”。
据信阿桑奇很熟悉那两名妇女。瑞典的消息人士称,她们一直不太愿意向警方报案
。但瑞典警察调查这一事件的消息被泄露给了《快报》,从而引发了外... 阅读全帖

In the wake of revelations around the extent of the NSA surveillance
programs it’s worth asking how such a program would operate, from a
technical standpoint. The feds have been collecting cell phone, Internet and
credit card data and to detect — and ostensibly stop — crimes.

In that way, Prism helps justify specific, potentially personal searches.

Prism to work backward.

这一段最精彩
Deep in the oceans, hundreds of cables carry much of the world's phone and
Internet traffic. Since at least the early 1970s, the NSA has been tapping
foreign cables. It doesn't need permission. That's its job.
But Internet data doesn't care about borders. Send an email from Pakistan to
Afghanistan and it might pass through a mail server in the United States,
the same computer that handles messages to and from Americans. The NSA is

Not a security expert but here's my thought.
Signing guarantees the integrity of the source data. If encryption is done
after signing, then you have to always perform decryption before knowing
whether the data is reliable or not. In such case if the encryption
algorithm is not strong enough it will be more susceptible to brute force
attack.

Let me try it one more time.
Both schemes have their pros and cons.
In the real word Signing is usually implemented with asymmetric key and
encryption (of large data) usually uses symmetric key.
The reason is that signing is usually performed on the hash of the message
only thus it can afford the low efficiency of asymmetric algorithm, while
encryption is performed on the entire message and symmetric algorithm is
much faster.

I don't think in the real world it will be a problem as long as both schemes
are implemented properly.
But there could be chance in the bad implementation that the encryption key
is connection based thus the receiver still decrypts the message but is made
believe that the message is from B instead of A.
