It is supposed to be absolutely secure – a means to transmit secret information between two parties with no possibility of someone eavesdropping. Yet quantum cryptography, according to some engineers, ...

As quantum computing advances, discussions around the future of cryptography are becoming increasingly common. In many conversations, one message is often heard: in the future, only quantum-safe ...

Researchers at Penn Engineering have created a chip that outstrips the security and robustness of existing quantum communications hardware. Their technology communicates in "qudits," doubling the ...

Andreas Poppe at the University of Vienna and colleagues at ARC Seibersdorf Research in Austria and Ludwig-Maximillians University in Germany used an entangled-state quantum cryptography system that ...

NEC has delayed the introduction of its first quantum cryptography system by three to four years due to performance and cost issues, the company said Tuesday. NEC had originally planned to start ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...
