encryption

Manned Air Force jets and drones could soon send high quality video and audio by using ultra-high bandwidth lasers, transmitting critical battlefield data faster than ever. The Air Force Office of Scientific Research has conducted experiments that transmit data without interference across almost 22 miles, both in the air and on the ground.

Researchers at Princeton have discovered that with a can of duster and a laptop, it takes only matter of minutes to crack most encryption software, including BitLocker, FileVault, dm-crypt and TrueCrypt. The weak link that makes this ridiculously simple hack possible is the DRAM chip. Heres why: Any time your computer is on, that chip contains the key used to access encrypted data on your hard drive. Once that chip loses power, the bits stored on it are supposed to disappear immediately. But thats not really what happens.
