Attack on computer memory reveals vulnerability of widely used security systems
Attack on computer memory reveals vulnerability of widely used security systems .
An interesting news about breaking into laptops, which are "secured" by encrypting disks. TrueCrypt is also vulnerable (due to generic design of the encryption suite).
"Disk encryption technologies rely on the use of secret keys -- essentially large random numbers -- to encode and protect information. Computers need these keys to access files stored on their own hard disks or other storage systems. Once an authorized user has typed in a password, computers typically store the keys in the temporary RAM so that protected information can be accessed regularly. The keys are meant to disappear as soon as the RAM chips lose power."
