One of the principal challenges of resource sharing on data communication network is its security. This is premised on the fact that once there is connectivity between computers sharing some resources ...

DEF CON 33, the world's largest security event held in Las Vegas in August 2025, Konstantinos Karagiannis, a leading expert in quantum computing and cybersecurity, gave a presentation titled ' ...

Recent developments in Wireless Sensor Network (WSN) technology have made it possible to create optimal cost and power efficient power efficient design of sensor nodes with multiple functions. In ...

Classical public-key cryptography derives its security from integer factorisation. Diagram by Venus Kolhi. Quantum computers bring exponential computing power, ultrafast calculations, advanced ...

Secure image transmission requires robust algorithms to ensure authentication, integrity, non-repudiation, and confidentiality. Addressing emerging security challenges necessitates continuous ...

A researcher from the Google Quantum AI research team has estimated that a quantum computer with less than a million noisy qubits could undermine the security of RSA-2048 encryption that secures ...

Public key cryptography is an encryption method that uses different keys for encryption and decryption. For example, when Bob and Alice interact, Alice creates a private key and a public key, and ...

Modern encryption relies on mathematical assumptions that quantum computers may soon render obsolete. This technological shift creates new ...

Delaying the transition to post-quantum cryptography (PQC) risks irreversible data breaches, regulatory penalties, and massive financial disruption. Cybercriminals aren't waiting for a quantum ...
