US computer scientists are preparing to unveil details of a technique that sends secret messages over public fibre-optic networks by hiding the transmission in background interference.
Bernard Wu and Evgenii Narimanov of Princeton University will detail their technique for "inexpensive, widespread and secure" transmission of confidential and sensitive data at this week's annual meeting of the Optical Society of America.
A team of researchers from Northwestern University in the US and BBN Technologies have demonstrated the world's first working quantum cryptography network. Northwestern University's Dr Gregory Kanter, who coordinated the demonstration, talks to Liz Tay about the basics of quantum cryptography and its potential for use in security systems of the future.
What is quantum cryptography?
The term snake oil is often used to describe cryptography that does not actually provide the level of security that its proponents claim. The origin of the term is somewhat unclear, but one story is that it can be traced back to one of the traditional remedies for joint pain and inflammation that was brought to the US in the nineteenth century by Chinese immigrants.
One thing became glaringly clear to organizations in 2005?storage security must be improved in order to avoid the public relations and logistical nightmares that have surprised both consumers and corporate chief information officers. Recent events are enough to keep storage and backup professionals up at night.
Mobile security specialist, Safeboot, has launched one of the first products that can transparently encrypt and decrypt data held on Windows mobile PDAs and smartphones.
Data Encryption and Secure Access Control for Windows Mobile is unusual in that it integrates with the device, and requires no user intervention other than a passphrase.
