Security Proofs in Quantum Cryptography
A security proof in cryptography is a formal demonstration that a cryptographic protocol is secure under certain assumptions. In classical cryptography, these assumptions are often based on the hardness of….
Device-Independent QKD
Device-Independent Quantum Key Distribution (DI-QKD) is an advanced form of quantum key distribution that provides the highest level of security, even if the devices used in the protocol are untrusted….
E91 Protocol
The E91 Protocol is a Quantum Key Distribution (QKD) method proposed by physicist Artur Ekert in 1991. It was a significant development in quantum cryptography because it uses quantum entanglement….
BB84 Protocol
The BB84 Protocol, proposed by Charles Bennett and Gilles Brassard in 1984, is the first and most widely known Quantum Key Distribution (QKD) method. It allows two parties—commonly called Alice….
Quantum Key Distribution (QKD)
Quantum Key Distribution (QKD) is a method of securely sharing secret keys between two parties using the principles of quantum mechanics. It allows two people—commonly called Alice and Bob—to communicate….
Photonic Quantum Computing
Photonic quantum computing uses particles of light, known as photons, to carry and process quantum information. Instead of using physical matter like electrons or ions, it harnesses the unique quantum….
Quantum Computing and Cryptography
Quantum computing is transforming the field of cryptography by introducing both threats and opportunities. While quantum computers promise unparalleled computational power, they also pose a major risk to traditional encryption….
Quantum cryptography: The future of cybersecurity
In the digital age, cybersecurity is one of the most critical concerns for individuals, businesses, and governments. Traditional encryption methods rely on mathematical complexity, but advances in quantum computing threaten….
Quantum communication: The next step in secure data transfer
In an era of increasing cyber threats and data breaches, traditional encryption methods face growing vulnerabilities, especially with the rise of quantum computing. Future quantum computers could potentially break current….
