DARPA initiates technology to prevent cyber attack
Category : General 27 Dec 2010 10:53 AM | Industry News
Two of DARPA’s cybersecurity programs are Clean-slate Design of Resilient, Adaptive, Secure Hosts (CRASH) and Programming Computation on Encrypted Data (PROCEED). The CRASH cybersecurity program is aimed at developing a Department of Defense computer network resistant to cyberattacks. After initial attacks, the system would learn and adapt ways to fight future attacks.
CRASH aims to develop new computer systems that resist cyber attacks the same way organisms fight bacteria and viruses. Gabriel says the researchers are developing computer hardware that gives systems a kind of genetic diversity that would make them more resistant to cyber infections by learning from attacks and repairing themselves. He notes that over the last two decades, the lines of code in security software has increased from approximately 10,000 to about 10 million lines, but the number of lines of code in malware has remained constant at about 125 lines. This analysis and others "led us to understand that many of the things we're doing are useful, but they're not convergent with the problem," Gabriel says.
The PROCEED program is working to improve the efficiency of working on encrypted data that has not been decrypted. "If we were able to do relevant sorts of operations without ever having to decrypt, that would be a tremendous gain because . . . whenever you decrypt into the open, you create vulnerability," Gabriel says.
