...keys are personalized and only one is needed for a person to gain access to all the data that should be available to them. In addition to simplifying the key process, this idea allows userswith proper access rightsto search encrypted volumes for specific information The key used here is a personal key which contains attributes of a person...

BlackBerry Giving Encryption Keys to Indian Government

2008-05-21 14:09:54 by schneier in Schneier on Security
 
RIM encrypts e-mail between BlackBerry devices and the server the server with 236-bit AES encryption. The Indian government doesn't like this at all; they want to snoop on the data. RIM's response was basically: that's not possible. The Indian government's counter was: Then we'll ban BlackBerries. After months of threats, it looks like RIM is...

The Keys to RFID Privacy

2008-07-25 00:00:00 by Dr. Ari Juels in Speaking of Security, the RSA Blog and Podcast
 
Data-security vendors sometimes get tall orders from customers. Not unheard of are: "I'd like a good digital signature system... with 20-bit keys" and "I want to use one-time pads for encryption... and I need to compress them." But one of the most challenging I've heard was recently offered up by colleagues in the RFID (Radio-Frequency...

Cold Boot Attacks Against Disk Encryption

...keys in DRAM. This was thought to be safe because the operating system would keep any malicious programs from accessing the keys in memory, and there was no way to get rid of the operating system without cutting power to the machine, which everybody knew would cause the keys to be erased Our results show that an attacker can cut power to the...
