Research found that computer encryption is no longer effective in the way of cracking

American researchers said today that people are used to protect the encryption of confidential computer dataProgramThey no longer work, because they have discovered a way to crack.

 
The electronic Forward Foundation (EFF) pointed out that if a computer falls into the hands of smart thieves, the "major security loss" of several popular encryption software will give a clear view of the protected information.
"People trust encryption programs to protect confidential information when computers are not at hand," said Shang en, an eff technician ." Sean is a member of the research team.

However, he said: "whether the computer is stolen or the airport security check leaves sight for a few minutes, smart thieves can read internal information ."

Researchers claim they have cracked several common encryption programs, including Microsoft's bitlocker, Apple's filevault, truecrypt, and DM-crypt.

In a report published on the Internet, the researchers pointed out that after the computer is shut down, the security lock and password of the encryption program still have temporary memory, allowing the information to be hacked.

"We found that the random access to data in the memory seems to be still there once the power is turned on again after most computers are powered off for a few seconds," said Abbott, a researcher.

"We write a program to collect memory content after the boot ."

The results show that the laptop is most vulnerable to intrusion when security lock, sleep status, or sleep mode is enabled.

The researchers said that many computer disk encryption systems have very similar structures and therefore may be cracked.

The report pointed out that shutting down the computer completely helps prevent intrusion, but it is not completely effective.
