安全通信

Such unknowns make it possible for seemingly long-gone data to turn up in a court under the order of a subpoena, or worse, in the hands of a hacker. On August 13th, though, a team of computer scientists led by Roxana Geambasu of the University of Washington, Seattle will unveil to the 18th USENIX Security Symposium in Montreal an e-communications system that destroys messages soon after they have been sent.

这种未知性，使得很久以前的数据似乎很有可能随时被传上法庭，更糟糕的是落入黑客之手。8月13日，在蒙特利尔召开的第18届USENIX安全专题讨论会上，西雅图华盛顿大学以Roxana Geambasu为首的计算机科学小组将推出一套全新的电子通信系统，该系统能够在信息发送完后不久将其销毁。
