Los Alamos Lab Uses Quantum Physics for Mobile Security

Through quantum cryptography, researchers at Los Alamos National Laboratory researchers have invented a new system to secure large transfers of information between mobile devices. LANL recently released information about the QKarD, a miniature transmitter which generates random cryptographic keys to encode and decode information. LANL says the QKarD uses the …

Hackers Blind Quantum Cryptographers with 'Invisible' Attack

Quantum hackers have performed the first ‘”invisible” attack on two commercial quantum cryptographic systems by using lasers on the systems, Nature News reports. By using lasers—which employ quantum states of light to encrypt information for transmission—the hackers were able to crack the encryption keys on the commercial quantum systems, without …

Researchers Claim Unbreakable Cryptography

A group of researchers claim to have developed a way to encrypt messages so a user must be in a specific geolocation to unlock the message. The position-based quantum cryptography is currently scheduled to be presented at the 2010 IEEE Symposium on Foundations of Computer Science, which takes place in …

Quantum Cryptography Hacked

Quantum cryptography is widely considered to be one of the most secure methods of communication, as the cryptography is alleged to be unbreakable. Researchers at the University of Toronto appear to have contradicted that myth, however. Feihu Xu, Bing Qi and Hoi-Kwong Lo claim to have successfully broken a commercial …
