Pulses of light to encrypt data and protect security of cryptocurrencies
(PHYSorg.com Physics)

Data travels through thousands of miles of fiber optic cables underneath the world`s oceans-via pulses of light. And according to experts, the data in these cables is at great risk of being intercepted. However, a newly designed frequency comb-recently developed by researchers at the USC Viterbi School of Engineering might be an effective tool for data encryption.
