U.S. researchers found ways to break the computer encryption is no longer effective
2009-01-20 at 10:34 pm hugegeU.S. researchers said today, people used to protect confidential information, computer encryption program is no longer useful, because they have found ways to crack.
“Electronic Frontier Foundation” (EFF) pointed out that the computer if falling into the hands of clever thieves, a number of popular encryption software “significant security error”, will be protected information glance.
EFF Shane scientific and technological personnel, said: “When the computer is not in hand, people trust encryption program to protect confidential information.” Shane is a member of the research team.
However, he said: “Regardless of the computer was stolen, or for airport security to leave the line of sight a few minutes, clever thief can read internal information.”
The researchers claimed that they had cracked several commonly used encryption programs, including Microsoft’s BitLocker, Apple’s FileVault, TrueCrypt and dm-crypt.
In this report published in the network, the researchers pointed out that after the computer shuts down, encryption programs and password security lock is still a temporary memory, making the information very much jeopardized.
Eban researchers said: “We found that most of the computer off after a few seconds, once again open the power supply, random access memory where the information seems to be still.
“We write a program, in the boot after the gathering inside the contents of memory.”
The results showed that laptop safety lock in the open, sleep or hibernation mode, the most vulnerable to invasion.
The researchers said that many computer disk encryption systems are very similar to the structure, it may crack.
The report states that the computer completely shut down will help to prevent the invasion, but not entirely effective.
