IBM researchers entangled 120 qubits, setting a new benchmark for quantum computing. The GHZ “cat state” achieved fidelity of 0.56, proving full multi-qubit entanglement. Direct Fidelity Estimation ...

The 35-year-old saga of Kryptos, an enigmatic sculpture containing four encrypted messages outside the CIA headquarters, just took a bizarre twist. Though cryptographers broke the first three passages ...

Abstract: In the era of cloud storage and computing, Attribute-Based Encryption (ABE) has emerged as a promising technology for fine-grained access control of data. However, it faces significant ...

Abstract: The research work investigates the application of classical cryptography through the combined implementation of Playfair, Rail Fence, and Caesar ciphers in a layered encryption framework.

This is a simple web application that implements the Vigenère cipher. It allows users to encrypt a message using a specific keyword. The project was created to demonstrate fundamental concepts of ...
