Researchers have taken a significant step toward making quantum cryptography more cost-effective. The National Security Agency has intercepted encryption keys to stealthily decrypt and eavesdrop on secure communications on the Internet, according to a news report. More research is needed before organizations can secure their communications using this advanced technology for exchanging encryption keys, experts say. The mathematics of cryptography is still the strongest link of security, while the rest of security is so weak, says Bruce Schneier, chief technology officer at the technology firm BT.”]
